Survive 10 Multiplayer Survival Matches
Survival of the Fittest

These are pretty straightforward, all you have to do is play the game and beat the boss in a multiplayer game. You'll get these over time.






Give 500 Dosh
While in game, you'll be able to throw money to another player. Check your settings to find which key it is but by default it is B. Press and hold this to chuck money on the ground and have another player pick it up. You'll likely get this naturally anyway.

At the time of writing, the trigger for this to appear seems to be misplaced. Try executing a Scrake or Fleshpound (whichever of those two achievements you don't have) and see if it procs. Following this logic, I would also assume it appears alongside the end of match/boss achievements too.

Revive a Downed Teammate
Occasionally, or frequently on higher difficulties, you'll see a player fall over. Run up to them and interact to get them back up. Voila, you are Medic main now.

Heal Teammates for 500 HP
As Medic, you'll get a heal dart equipped to your weapon. Shoot this at teammates who've lost health and eventually you'll get the achievement pop up.

Execute a Fleshpound

Scrake, Rattle and Roll
Execute a Scrake

Towards the end of the lives of these enemies, they will get on their knees. This happens when enough bodily damage is done, if lethal critical damage is done, they will not be available for execution. Run up to them and interact to initiate the cutscene. Be quick though, they only stay there for roughly 5 seconds.






Defeat a Queen Crawler on Normal

Royal Flush
Defeat a Queen Crawler on Hard
Reign Supreme
Defeat a Queen Crawler on Hell on Earth

These all relate to the Queen Crawler, as you might have guessed. All straightforward and simple. However, I would like to outline some tips and advice for her.

Keep in mind that all bosses can use their phase one attacks during phase two. They will also beeline for a downed player to execute them, so if no one can revive them beforehand, take advantage by restocking or laying into the boss while they're trying to execute.

• Mire Balls - At any point of the match, the Queen Crawler can shoot out mire balls that stick to the ground and cause an explosion when run over. You can either shoot these during flight or destroy them after they've hit the ground. Just don't run over them.
  
  
• Tail Whip - With her tail/abdomen thingy, she can whip it on the ground or side to side. Ninjas beware, this is a very damaging attack so be wary or block if you see it happen. If you're someone else, just don't get too close if you can help it and dash slide out to dodge as the range is quite large.

• Portal Crawl - Upon entering the second phase, she will burrow and open up more portals that spawn mini crawlers. Best way to counter this is to use a crowd control ability or weapon, such as the flamethrower or grenade launcher, to easily dispatch them. Then when the boss comes back up, you'll know as the portal will be bigger than the others, she will initiate a charge. Move out of the way or gain enough distance.
  
  
• Portal Spam - I find this happens more toward the death of the boss. The Queen will portal down and charge after coming back up, leaving mini crawlers as she does so. She will do this attack very quickly and often until she either hits a player or is interrupted. Obviously, to counter, interrupt her as she is charging or coming back up.

Defeat the Chimera on Normal

Defeat the Chimera on Hard
Chimerical Cure
Defeat the Chimera on Hell on Earth

Yet again, relating to the Chimera. More advice below.

Keep in mind that all bosses can use their phase one attacks during phase two. They will also beeline for a downed player to execute them, so if no one can revive them beforehand, take advantage by restocking or laying into the boss while they're trying to execute.

A new enemy type will spawn called 'Mires' and they are effectively mini Chimeras. Easy enough to kill however.

• Symbiote Strike - Extends many tendrils from it's body that can damage in all directions. All I can say here is keep your distance, the attack is fast. It is telegraphed by it standing still and 'charging up' its stomach.
  
  
• Leaping Strike - It will charge up and jump at you from a fair distance away. Dodge or dash out of the range, fairly simple.
  
  
• Tendril Pillars - The Chimera will slam the ground and produce a wide radial area of tendril pillars which do a serious amount of damage. If possible, just run away. There is no counter to this.
  
  
• Frontal Pillars - Exactly the same as the previous attack but it fires in a straight line instead. Dodging to the side can avoid it.
  
  
• Ranged Balls - It can periodically shoot out slow little orange balls. Either shoot to destroy or dodge away.

The new teleport ability will target the current furthest person away from the boss, and immediately execute an attack.

• Teleport and Melee - Upon teleporting, after it lands, it will do a melee attack. Just stay clear of where it teleports to, it's highlighted by a purple glow shortly before it lands.
  
  
• Teleport and Ranged - Same as the melee except it will shoot a tendril attack or orange balls at you.
  
  
• AoE Burst - It will sprint towards you and initiate a large purple electrical storm and then quickly expel it. Just run away, as with all AoE attacks, they're difficult to dodge.

Defeat an Impaler on Normal

Sharp Instincts
Defeat an Impaler on Hard
A Cut Above
Defeat an Impaler on Hell on Earth

Finally, we reach the Impaler. More advice below.

Keep in mind that all bosses can use their phase one attacks during phase two. They will also beeline for a downed player to execute them, so if no one can revive them beforehand, take advantage by restocking or laying into the boss while they're trying to execute.

• Distance Charge/Leap - It will literally just rhino charge you. Move out of the way, if you can, before it hits you. Dodging/dashing can help with this.
  
  
• Single Arm Rockets - He can quickly fire a single rocket at you after a quick telegraph of him aiming beforehand. Stay clear or try and get behind cover before it lands.
  
  
• Double Arm Rockets - A longer telegraph with both arms outstretched is the double rockets. Same advice as single arm, if you're close enough to cover, move into it and stay clear as best you can. Dashing can move you out of the impact radius and only take splash if necessary. Getting hit by splash damage is better than impact damage.

After losing his armour, he will start to become more aggressive. especially in close range.

• Roll and Swipe - He will start a roll towards a player and then leap onto them causing a decent amount of damage. Again, try dashing out of the way or sprinting towards him during his roll, he will jump behind you instead of onto you.
  
  
• Double Swipe - He will swing his arms twice, right then left arm. Dodge backwards to avoid or sprint away.
  
  
• Smoke Attack - Periodically, The Impaler will throw out a smoke attack, limiting your vision and interfering with Medic healing darts. I can't offer any advice for this, maybe lure the boss outside of the smoke and continue attacking that way if the smoke itself is too detrimental.

Upgrade a Perk Skill

Maximum Potential
Upgrade a Perk Skill to the Max Tier

Both include levelling up a character to gain proficiency points. You now need to spend those proficiency points into any of the skills the character has and raise them to level 3 for Maximum Potential. The amount you need to get them to max tier is 225 points.






Reach Level 5 with Any Perk

Fifteen and Counting
Reach Level 15 with Any Perk
Thirty is Something
Reach Level 30 with Any Perk

All of these include levelling up your perks, obviously. To get them, just play the game and you'll eventually hit each one with a perk anyway. Doesn't take anything special. Pick your favourite character to play and play them. Ninja FTW tho.

Customise a Weapon

In the Armoury, in the Stronghold, select a weapon to customise and either craft a mod to put on the weapon or add a decal/ornament/skin.






Craft a Weapon Mod

Smooth Upgrader
Upgrade a Weapon Mod
Maximalist
Upgrade a Weapon Mod to the Max Tier

As briefly outlined in the previous achievement, select a weapon and hit the 'craft' button after creating a loadout. Then craft any mod, click it and proceed to upgrade it with components found in game. Upgrade the mod 3 times to obtain the 'Maximalist' achievement.

Complete a Story Assignment

Under the Mission Assignments in the Stronghold or Scoreboard menu in game, you can select and see what you have to do for the Story. The first mission will be pinned automatically, go to Army Depot and complete it. Although, make sure it's active just in case beforehand.

Activate a Zipline
Around the maps you play, you'll find 'fast travel' items called ziplines. Interact and use them with the Multitool to unlock them.

Activate a Turret
Same as 'Zip It Up', use a Multitool to activate a turret. These are found in key locations around maps, such as the testing cells in the Lab map.

Unlock an Armour Locker
Again, same as 'Zip It Up' and 'Turret Captain'. Use a Multitool to unlock an Armour Crate located around maps. They are large and glow, hard to miss.

Use Multitool to Unlock an item
Selecting the Engineer or equipping the Multitool mid match, open an Armour Crate, or activate a zipline, turret or locked door.

Survive a Weekly Operation
In the Mission Select menu, you'll see an icon and larger button above the matchmaking and play button. This is the weekly operation, find the map it is based in and complete it.

Since I've had a few websites rip my guide from Steam, know that this is the only place I submit my guides. If you see this anywhere else, it was not from me and I do not condone the practice.
