• Wolf is the action skill of Wilhelm. You need to reach level 3 in order to unlock it and you can start to use it immediately to kill your enemies. You can shoot enemies until they have but a small amount of health left, then use the action skill for an easy kill.

• Aspis is the action skill of Athena. You need to reach level 3 in order to unlock it and you can start to use it immediately to kill your enemies. You can shoot enemies until they have but a small amount of health left, then use the action skill for an easy kill.

• Showdown is the action skill of Nisha and you will need to reach level 3 in order to unlock it. You will need to invest in the skill called "Ruthless" which is in the "Fan the Hammer" skill tree. For each point invested into this you will get 0.1 seconds added to the time of Showdown for each kill you get while it is active. You will want at least 3 skill points added to it to have enough time to kill 10 enemies, meaning that a level 6 Nisha will be necessary for this achievement.

• Vault Hunter.EXE is the Claptraps action skill. You unlock this as with all characters at level 3 and can immediately begin using it. How it works is that when you activate it, the game will evaluate the current battlefield conditions and assign an appropriate temporary battlefield "care package", although this is mostly a random outcome. You will need to be level 25 with the Claptrap to have enough skill points to unlock the .EXE modes through the skill trees. After getting to level 25 you can unlock and trigger the modes in one of the skill trees, then re-spec your character and do the next skill tree, then again for your third and final time.

• There are 9 default modes that are available from the beginning, 4 modes that need to be unlocked with skill points and 2 of which require that you are playing in Co-Op and are marked as such below:

• Med Bot - Shoot laser at teammates to heal them (co-op);
  

• Nonsensical Sacrifice - Revives teammates that are currently down at the cost of your own life (co-op);
  

• Torgue Fiesta - Claptrap will emit a series of live grenades in random directions;
  

• Laser Inferno - A disco ball floats above Claptrap's Head, constantly shooting lasers;
  

• One Shot Wonder - One pull of the trigger unloads all ammo left in the magazine at once;
  

• Pirate Ship Mode - Claptrap dons a pirate hat atop a mast and four cannons, which automatically fire;
  

• Gun Wizard - Provides a +100% bonus to rate of fire, reload speed, and magazine size
  

• Clap-In-The-Box - Claptrap digistructs a large bomb, which will explode after a short delay;
  

• See "Moon Mission Meister" achievement section.

You get side missions from various characters that you meet along the journey, as well as from mission boards. Whenever you notice a yellow exclamation mark on your map you should investigate it immediately as it is a side mission. You do not have to do them right away but if you pick them up as soon as you notice them you'll have them in your journal ready to complete. Some of the side missions will appear in your journal as "Undiscovered" so you know that you need to go and pick it up from whichever area it is in, but not all of them do this. You should check back through all of the areas every so often to be sure there aren't any that have become available without you knowing.

Note that some side missions take you to certain areas that you otherwise would not go to, so doing them all ensures that you get all of the secret areas for the achievement 'Cosmic Completionist'.

Below is a list of all of the side missions in the order you acquire them and where from. I've noted in the lists the side missions that pertain to their own separate achievements.

To unlock this achievement, you will need to attack a Lost legion Eternal without killing it to force it to evolve during combat. There are 2 ways to do this.

You can get one to change into an Eternal Unstable/Instability (both names do the same thing). After you have them in this state, they will explode after a few seconds. You will need to lure 3 enemies near him and hopefully they are in it's blast radius when it explodes. The form they change into is seemingly random so it may take a few tries to get the right evolution.

The alternative way to do this is to get one to evolve into a Eternal Magus and they will shoot purple energy at you. If you try to position an enemy between you and the Eternal Magus they will be damaged by the splash of the Magus' attack. Try to have 3 such enemies killed this way for the achievement.

You can find the Lost Legion Eternals in the area Vorago Solitude and Tycho's Ribs.

• There are 8 Moxxtails in her bar in Concordia. They are all lined up on her bar and can be purchased at any time with Moonstones. They are essentially temporary perks and each last a whopping 30 minutes. You will need a total of 80 Moonstones (if you buy them in Normal Mode) or 160 Moonstones (if you buy them in True Vault Hunter Mode or Ultimate Vault Hunter Mode) to purchased them all, so try to keep a note of which ones you have used. It is worth noting that although you can only have 1 active at a time, you can buy them all at once one after another, as when you buy the next it will over-write the previous, so if you have 80 Moonstone you can do them all at once without having to wait 30 minutes between each one.

• Moonstone chests are just loot chests but they require 40 Moonstone to unlock and reveal the goodies within. Loot 10 such Moonstone chests and the achievement is yours. You can usually find these chests after a boss battle.
  
  
• A good chest to boost for this can be found at the end of "Titan Robot Production Plant" where you defeat "Rampant Felicity" during the mission "Let's Build A Robot Army". When you fast travel to the area it will only take you a few minutes to run to the opposite end of the map. At the back of the room where you fight Rampant Felicity there are 2 shutters that open after you defeat her, one has a fast travel behind it, the other has the Moonstone chest. Run to it, open it, save and quit, then repeat until the achievement unlocks.

If you open your Journal in-game and scroll to the right you will find a list of challenges that you can complete. Doing so will give you points to your 'Badass Rank' which will allow you to add permanent upgrades to your character.

You can hover over any of the challenges to see what they entail. The majority of challenges have 5 levels, with some having as few as 1, but you will only need to complete the first level of each challenge to unlock this achievement. The challenges that have only 1 level are not required for this achievement.

There are 2 challenges that only unlock after you have completed all 5 levels of a specific challenge. The first is a Shotgun challenge called 'Over Achiever' and you need to have completed all 5 levels of the Shotgun challenge 'Take It All!' to unlock it. This requires that you kill 750 enemies at point blank range with a Shotgun, so try to be conscious of this while using Shotguns.

The other challenge that needs to be unlocked is the Rocket Launcher challenge, 'Missile Magnet' and you will need to complete all 5 levels of the challenge 'Collateral Damage' to unlock it. This requires that you kill 200 enemies via splash damage with a Rocket Launcher so try to be conscious of this when using one.

Although you need to unlock these 2 challenges, you will accumulate towards them before they are unlocked so that when you do unlock them, you may have already done multiple levels.

• Secret achievement. This side mission is found quite early on in the "Triton Flats" area. You need to find 50 common rarity weapons (you can only deposit guns so don't collect any grenade mods), which are the white weapons and donate them into a mailbox. After every 10 weapons you deposit you will be given another task to do in the mission, but it is usually a short task within the area where you have to deposit the guns. After you have deposited all 50 guns you will need to travel to Concordia and witness the "revolution" that you are now solely responsible for. Turn it in for the achievement and a nice shiny legendary oz kit. This mission is also needed for the "Moon Mission Meister" achievement.

SECRET
This achievement is missable if you choose incorrectly at the end of the mission.

To unlock this achievement yo will need to complete a side mission called 'Guardian Hunter'. You can only get the mission when you have completed the mission 'The Beginning of the End' and thus completed the game. You will find it in 'Vorago Solitude' given to you by 'Sterwin'. Complete the mission being very careful to choose correctly.

You will be tasked with capturing 1 of each type of elemental guardian and after doing this you will need to go to a 'Drop Off' point and deliver the specimens. When you get there however you are given a choice of how to complete the mission. You can Kill the Master Poacher, saving the Guardians and unlocking the achievement, or you can give the Guardians to the Master Poacher. Of course for the achievement you will need to kill the Master poacher. When you attack him he'll be joined by a handful of Scavs, just kill them all and the achievement is yours.

• Secret achievement. To unlock this achievement you will need to complete a side mission called "Don't Shoot the Messenger" that you can find in the "Tycho's Ribs" area. It's a pretty basic mission that will take the best part of about 10 minutes. Complete it for the achievement. This mission is also needed for the "Moon Mission Meister" achievement.

• Secret achievement. To unlock this achievement you will need to complete a side mission called "The Secret Chamber" that you will receive from Davis Pickle in Outlands Canyon. You can only acquire this mission after defeating "Bosun" during the story mission "Inteligences Of The Artificial Persuasion". This mission is also needed for the "Moon Mission Meister" achievement.

SECRET
This achievement is tied with completing a various selection of side missions that all involve launching rockets off the surface of Elpis. The missions you must complete are as follows:

✦"Wiping the Slate" - found in Concordia AFTER completing the story mission "A New Direction"
✦"No Such Thing as Free Launch" - given by Cosmo Wishbone in Triton Flats
✦"Home Delivery" - found in Concordia AFTER completing story mission "Watch Your Step"
✦"It Ain't Rocket Surgery" - Found in Research & Development AFTER completing the story mission ✦"Science and Violence"
After completing the four side missions listed above, the achievement will unlock. Take note that there is no set order that you have to complete the missions, so you can complete the missions in any order you desire.

After you have completed the story you can fast travel back to Concordia and there will be a new side mission available, 'The Bestest Story Ever Told'. You will need to travel back to Eleseer where you defeated the final boss to find this new Invincible version of the boss in it's place that you then need to defeat. Good luck and if you need people to help you with this, consult the Achievement Boosting thread found Here. Note that you need to defeat this boss, completing the side mission to also unlock the "Moon Mission Meister" achievement.

NOTE: The boss will be level 28 on Normal Mode no matter what. So, if you are having trouble with him, try progressing in your second playthrough so you are a higher level with higher level gear and then returning to Normal Mode to defeat the boss with out any trouble.

The achievement will unlock after killing the boss on either playthrough.

• Secret achievement. Excalibastard can be found stuck in a stone in "Stantons Liver" area. You will need a Badass Rank of 2500 or over and you will only get the gun once (per character), so it may be best to wait until you are maximum level so that you get the best possible version of it. As you enter the area from Triton Flats, look on your map and notice at the top of the map there are 2 small areas not connected to the rest of the map. Excalibastard is at the top of the most northerly area.
  

Pretty much as ridiculous as it sounds. It shouldn't be too hard as the lack of gravity in the game means you will have a lot of time in the air. The difficulty lies in hitting the enemies with your sniper after your 360 degree spin.

There is a good place to get this achievement quite early on, but it is a little temperamental. Play through a few missions - mainly Springs sides - until she gives you 'Tales from Elpis'. It shouldn't take you more than 5 minutes to complete and the award is a sniper rifle.

Now head out around the corner from the base and find a Kraggon Pebble. Double jump in the air do a spin a little over a 360, so either a 540/720. The Kraggon Pebble should 99% of the time be directly below you, so look down and shot for a 1-hit kill and the achievement.

Besides this, most simple enemies will count and you can always wait until you're a high level then return to one of the earlier stages of the game for a guaranteed 1 hit kill.

• All of the equipable weapons and items in Borderlands are colour coded. White is the lowest quality, while Orange is the highest (excluding Glitch weapons from the Claptastic Voyage DLC). Purple, which you need for this achievement is the second highest quality gear in the game. For this achievement, you need to have a Purple or rarer piece of gear in each slot. That means a purple or rarer weapon in all 4 weapon slots, class mod, oz kit, shield, and grenade mod. All of these will most likely be found with natural exploration and looting, but you might have to farm a bit for a purple class mod. I suggest buying that as the item of the day at one of the vending machines to speed up this progress. You can also try using the grinder to create the purple items, however this will take a bit of effort. If you're having trouble finding Purple rated gear, consider adding me for help.

SECRET
This achievement is missable. Do not complete this mission without 4 other people if you want this achievement.

The first of the 2 'Sub-Level 13' mission is obtained from Pickle in the Outlands Canyon after completing the story mission 'Home Sweet Home'. The second Sub-Level 13 mission is obtained upon turning the first mission in. You will need to complete these 2 missions with 3 other players to unlock this achievement. If you need some people to play with, consult the achievement boosting thread found Here.

Note that you can do this with 2 people both using a second controller with guest accounts logged in.

Tip: At the end of the second Sub-Level 13 mission you can choose who to turn the mission in to. If you turn it into the 'Fast Travel' in the area where you finish the mission you can keep the unique 'E-Gun' which is extremely good. If you turn it in to Pickle you get an average Grenade Mod, so I would turn it in to the Fast Travel for the E-Gun.

• You unlock the ability to use the grinder after finishing the side mission "Grinders" which is given to you by Janey Springs after finishing the "A New Direction" story quest. Then you just need to make a weapon combination in the grinder to unlock the achievement.

• To unlock this achievement you will need to either put two Orange guns and one Purple gun into the Grinder as well as Moonstone or use 3 purple weapons until you get a legendary weapon from the grind process.

For this achievement you will need to survive in the oxygen starved outdoors of the moon for 5 whole minutes after your Oz has ran out without replenishing it. The best way for this would first to be a rather high level so that you have a lot of Health, and also that you have a Health Regeneration perk active from a Class Mod or a Co-Op partners Class Mod. As long as your Health Regeneration exceeds your slow oxygen starved death, you will survive forever in this state. Do this for 5 minutes and the achievement is yours.

You can obtain this achievement as you discover Moxxi's bar in Concordia. The drink costs 10 Moonstones, and it is the one called “Squill Syrup”. And it will give you a 0.8% health regeneration for 30 minutes. Go somewhere where there aren’t any enemies after taking the drink and remove your oz kit. The health regeneration will cancel out the damage, so you can stand there for five minutes and survive.

This CANNOT be obtained using ClapTrap as he is a robot and thus does not require oxygen to survive.

• Secret achievement. To unlock this achievement you will need to first complete a precursor side mission called "The Voyage of Captain Chef" that you can find in Triton Flats after the story mission "Let's Build A Robot Army". Then later on in the game when you are able to travel to an area called "Vorago Solitude" you can find the mission "Return of Captain Chef", which is the mission you need to complete for this achievement. This mission is also needed for the "Moon Mission Meister" achievement.
  

The Stingray is a vehicle that you unlock during the story mission 'Intelligences Of The Artificial Persuasion'. The vehicle is a hover bike and you can hover upwards then slam back down as an attack.

To unlock this achievement, you need to do this slam attack on an enemy and kill it in the process. This is easily done on a Kraggon during the earlier stages of the game. This can also be done on a bandit vehicle, just be sure to shoot it first to bring it's health all the way down before slamming it for the kill.

• To unlock this achievement you will need to play in multiplayer. Simply challenge the other player to a duel by hitting them with a melee attack and defeat them to unlock this achievement.

To unlock this achievement you will need to freeze 3 enemies at once. You can do this by having 3 enemies gather near a 'Cryo Vine' which you can find in the frozen areas and when you shoot them they explode and freeze whoever is near-by. When you have the 3 enemies frozen you need to jump up then hold to slam back down, shattering the enemies all at once.

It would be easiest to do this to 3 Kraggon Pebbles or 3 Torks as they both charge you and only melee attack you. You should be able to lure 3 of them near to a Cryo Vine then shoot it and slam them for the achievement. You may need to have leveled up a tad to ensure your slam attack is powerful enough to shatter them, or to have a better Oz kit than you started with.

A good strategy for this achievement using a Laser gun. Later on in the game you can do a side mission called 'In Perfect Hiberbation' and during this mission you are given a gun called 'Lazlo's Freezeasy' which is a very low damage Laser gun but has a huge chance to easily freeze enemies. You can acquire this gun then leave the area and look for a group of Kraggons or Torks, freeze 3 of them with ease then slam attack them. Be aware that after completing this mission, you lose the gun so try to do it while the mission is active.

• The customization items are the skins and unique heads for your character as well as the vehicle skins. You find these as random loot and occasionally as quest rewards. You will have them put into your inventory when you acquire them so you'll have to 'use' each one by selecting it in your inventory. As you "use" your tenth customization item, the achievement will unlock.
  

There are multiple ways to unlock this achievement, but the end result is the same. You need to have all 4 status effects on a single enemy at one time.

You can try to do it the most simplistic way and have 1 of each weapon type equipped and try to ignite/freeze/corrode/electrocute them but you likely won't have enough time especially if you can't get one of the status effects to happen. It is theoretically possible to do it this way, but it's probably the most difficult.

Another way you can do this is to use Athena. In her Ceraunic Storm skill tree there is a skill that you can unlock called 'Smite'. Basically when you're airborne and shoot at an enemy a bolt of fire and lightning shoots down from the sky and this has a chance to ignite/electrocute the enemy. With this you can then equip a freeze weapon and jump then shoot an enemy trying to freeze them and hoping that Smite ignites/electrocutes them and then quickly switch to a corrosive weapon to try and corrode them while they're frozen/ignited/electrocuted.

You can also do it with a team. Have one person use a gun of each element and blast away on a tough enemy. I personally did this with a team using the stalker who eats the guy's key card in the "Science and Violence" story mission in R&D.

You can use Fragtrap's "Rainbow Coolant" skill (bottom of the far right tree). This will ignite, corrode, freeze, and shock an enemy with one button press.

You can also use barrels that do the various elemental effects as well as grenades, slam attacks and shield Nova explosions.

• You will need to play in multiplayer with a friend to unlock this achievement. Just have your buddy go into "Fight for your life" and then revive them with oxygen. This can easily be done in Concordia. Repeat 10 times and this achievement should unlock.

SECRET
The nine game modes are actually game modes as much as they are just circumstances that affect the actual Game Mode which is just a three-wave defence mission. They do spice it up a bit but this achievement is basically to complete the three-wave defence mission nine times with nine different circumstances. The Mutators give you character traits, such as more damage with certain weapons/attacks, etc. They are as follows;

Game Modes:
✦Half Gravity
✦Operation Vacu-Suck
✦Mag Density
✦Hyperspeed
✦Flow
✦Shoes Made of Acid
✦Vampires
✦Bloody Good
✦Glass Turtles
✦Mutators:
✦Butt Slayers
✦Rocket Arena
✦CQB
✦Rangefinder
✦TORGUE APPROVES THIS SH*T
✦Lasershow
✦Spray 'n' Pray
✦Critipistols
✦MOAR DOTS

After completing the first mission for the achievement 'It's Raining Cats and Hotdogs' you will gain free access to choose whichever Game Modes and Mutators you wish. I would suggest just starting from the beginning, choose the first of each, complete the mission, turn it in, then choose the second of each, complete that mission and so on, until you've done them all. You can also select the difficulty so be sure to set it to the easiest for to make this as smooth as possible. You do need to complete the mission, even though the achievement only suggests to 'Experience' them, as failing will not count towards Experiencing it. The first mission that you do for the achievement 'It's Raining Cats and Hotdogs' will count as one of the nine that you need to complete, so be sure to remember which Game Mode and Mutator you chose to avoid having to repeat it.

Complete all nine of each and the achievement is yours.

You will first see the SpyBugs in the location 'The Nexus.' They do not always spawn and hae a pretty low chance to do so, so seeing 10, much less killing 10 without the taking your photograph is unlikely to happen through natural progression. Luckily there is a spot that will spawn them on occasion that you can grind the kills out at.

In 'The Nexus' if you make your way to the Recycle Bin area that you first visit during the mission 'File Search,' two enemies will spawn every time to re-visit the area. Most of the time it will be AdBugs, but on occasion SpyBugs will also spawn there. Basically, go to The Nexus, make your way to the Recycle Bin and see the two enemies that spawn. If they're SpyBugs kill them quickly as they are materializing in front of you, if they aren't then save and quit, then load your game back up and run back there, it isn't far from where you spawn in. Rinse and repeat until you've killed 10 of them.

They are pesky enemies and if you don't manage to kill them quickly enough they will become invisible and circle you for a few minutes before they reveal themselves to try to snap a photograph so if this happens, you're better just saving and quitting and trying again.

These enemies will also spawn in the 'l33t h4X0rz' arena missions, but again they are few and far between so you're better off grinding them at the Recycle Bin in The Nexus.

Kill 10 before they snap your picture, shown by your screen flashing bright white for a moment and the achievement is yours.

SECRET
You will find the Holographic Projections in the location 'The Nexus.' They are podiums with the Holographic faces of some of the characters from the main game, such as Pickle and Lilith. All you need to do is walk up to them and press . There are five in total so talk to them all and the achievement is yours.

Walkthrough courtesy of Necrophage33;

Roland: From the fast-travel in Nexus, run to the right side of the giant Clap-trap to the Nurse Nina vending machine and he's on the right side of the vending machine if you're facing it.
Brick: Head back to the fast-travel station, and right before it make a right. Head down the stairs to the bottom, then hang a right under the awning. He's on the right near the Russian(?) bot.
Pickle: Head past Brick out the side opposite you entered from and you'll see a big pipe/tube below you. Drop down below this tube to the platform below it and Pickle is inside.
Janey Springs: From Pickle, boost jump to the lowest section of the big tube and then jump up onto the platform it connects to. Run to the other side of the platform and take the jump pad to the platform below where the garbage dump is. When you land, turn around to face the jump pad leading back up and Tannis will be on your right.
Lilith: From Janey Springs, turn back around and run past the garbage dump out onto the catwalk. Run past the jump pad and sign that says "Data Stream" and round the corner. Lilith, the last projection, will be there.

MISSABLE
SECRET

To unlock this achievement you need to acquire a side mission called 'Temple of Boom' and during it outrun a giant wheel that will be chasing you down a short tunnel.

To find the mission you will need to travel to the location 'Subconscious' and head to the area that looks like a child's play area. While here, if you look east you will roughly be looking at the exclamation mark on your map that belongs to this quest. At the edge of the map, looking east in the child's play area, there will be a jump pad to gain access to the area with this mission.

You will first be able to acquire this mission during the story mission 'END OF LINE' at the point were you need to look for Claptraps 'Hope' and 'Self Esteem.' The necessary jump pad will appear at this point and send you to where the 'Temple of Boom' mission is.

This achievement is missable as if you do not outrun the wheel in a sufficient manner then you will not have fulfilled the requirements for doing so and fail the optional objective that unlocks this achievement. As you are at the part where you are told to 'RUN' just run straight through the tunnel and towards the open archway at the end. As you reach the archway jump out of it and land on the platform in front and stand there a moment and the achievement will unlock. The reason this is missable is that there is a wide area at the end of the tunnel before the archway and you can run into it and avoid the wheel, but doing this, even though the wheel doesn't get you, will void the achievement and you will have to do it again on a different character.

• Achievements from this point on are part of The Holodome Onslaught DLC.

• See "I Welcome Your Attack, Fool" achievement section.

• See "I Welcome Your Attack, Fool" achievement section.

• An easy way to get all 3 achievements is to first complete the game twice on both Normal Mode and True Vault Hunter Mode and gear up. Afterwards, make your way back to Normal Mode and complete 5 rounds of the Holodome as well as the Badass Round. Being almost max level will help you take less damage and kill all enemies easily (since they are level capped around 35 ~ ish) making these 3 achievements a walk in the park.
