Perk loadout:

Tactical Reload: Obviously the best choice to make no matter the situation, it allows you to reload faster. Very reliable to get.

High Capacity Mags happens to be good too, but you need a good amount of skill when using it. Tactical Reload is more of simple and easy to use, very basic. Tactical Reload is also reliable in small room.

Fallback: Unquestionably the best, it increases your 9mm pistol and knife massively, you also get fast weapon switch. Thats more than enough reason to get it.

Impact Rounds helps gives you time to kill large zeds. But in this guide, we are not gonna focus on slaying large zeds so this must be ignored.

Tenacious: Reliable in terms of survival, if you know how to use your bullets wisely then get this because it'll save your life when dealing with large zeds.

Prepared is also useful, gives you more ammo. However, due to certain large zeds you have to deal with most of the time, its usually best to get Tenacious so you wont go down too fast.

Eat Lead: Reliable in terms of ammo, allowing you to kill more zeds before reloading

Hollow Point Rounds is also useful, you can kill zeds quicker that way. Though you have to use ammo more wisely comparing to Eat Lead, which is less pressuring to use.

ZED TIME- Machine Gunner: This works with Eat Lead, you will be able to shoot fast. Allowing you to kill zeds AND extend zed time easier this way.

ZED TIME- Tactician is pretty useful in terms of defense so you can reload or switch, but Machine Gunner can help your team alot with zed time extensions. Believe me, they'll need it. Especially if they are level 25 using their zed time ability, you'll be a big help in this one.

Gun loadout:

Scar-H: Its absolutely a must have due to having high firepower. I dont recommend using full auto on weaker zeds, just use semi auto since it takes about 2-3 shots to kill depending which you face, headshots take 1 shot which strongly recommend doing so since it'll help you get quicker kills and less ammo waste this way. Clots and Cysts for example, including slashers and gorefasts, shouldnt take so much ammo to kill. Sirens and Husks may take a bit of time to kill but possible with semi auto. If must, killing Quarter Pounds, EDARs, Scrakes, and Fleshpounds is a must with full auto due to having large amount of health. I would suggest targeting weaker zeds most of the time and let your team handle the large zeds.

Hmtech-401 Assault rifle: In terms of ammo pool and team survival, best weapon to use. It contains a huge amount of magazine, capable of killing a good amount of trash zeds, which helps when Machine Gunner comes into play during Zed Time. You can also keep your team alive as well.

Fully upgraded 9mm pistol: If you have setback, get this. This deadly pistol will be reliable with machine gunner as a backup weapon if you ever end up in a pickle when reloading or you are out of ammo for your assault rifle during Zed Time, you can quickly switch to 9mm pistol and quickly kill trash zeds. This will give you higher chance to extend zed time this way. Normally I dont talk about this since usually you can always upgrade 9mm on any perks, but this one is more important to get than the rest. As a weapon alone aside from zed time, its pretty reliable to use as well.

Optional:

Hmtech-101 pistol: Reliable if you want to heal your teammates, as a weapon alone it may not be useful. In my own opinion you are probably better off without it if you are gonna use medic assault rifle, that weapon alone is reliable.

Upgrading Scar-H and Medic Assault rifle: This one alone is reliable if you need more firepower, increasing your chance to kill zeds which helps with machine gunner so you can extend zed time easier. Its usually a must if you want to keep things going.

Dual 9mm pistol: Its okay but a single 9mm pistol alone is good enough. Carrying two would be helpful if you need more shots.

Stoner63: Replacing the medic assault rifle with this LMG helps you do more damage to zeds. Having more ammo such as Eat Lead and as well as Machine Gunner makes it more interesting to watch all the bullets fly as you kill lots of trash zeds. Reliable if you prefer more ammo and more focused on fighting than healing teammates.

FN FAL ACOG: Replacing Medic Assault Rifle with this high damage assault rifle. Capable of killing trash zeds easy, and you can knock out Scrake if you aim and shoot his head a good amount of times on full auto. The downside however, is low ammo. Use your shots wisely.

Tips:

As Commando, you want to focus on killing trash zeds. On Zed time, you want to focus on extending zed time by killing any weaker zeds you can find, every kill extends it. It is also VERY important to know that you MUST use semi auto if you dont want to waste too many bullets. Any gun that allows you to change fire mode, PLEASE change it to semi auto. If you cant, dont use up too much shots, and do NOT attack large zeds unless its a MUST, let your team handled them and do your best to ignore. HEADSHOTS ARE IMPORTANT FOR LESSER AMMO WASTE AND QUICKER KILLS. Also to add, you also can end up spending less dosh on ammo if you are strict with your shots.

Update: If you are confident, you can use full auto as long as you know how to control your shots. Problem was I seen people who dont know how to control their shots responsibly which not controlling them would lead to ammo waste and risk wasting all your ammo for that gun quickly if not handling it well. If you cant land headshots with this gun, switch to semi auto and work on it from there until you improve enough to use full auto. All you needed to do is one tap it, if you cant, just switch to semi auto.

In order to get the best weapons, you start off with Varmint Rifle. Keep your weapon for sometime and get Bullpup with it. Then from there, you build up getting ammo and getting more dosh. Repeating this way can lead you getting a Scar and Medic Assault rifle. Remember, the less ammo you waste, the more chance for you to get bigger guns this way. This is why semi auto plays such a important role in Commando. In case you didnt know, press the secondary fire to change fire mode. Some guns can do that, some dont. In this case, do it. ONLY go full auto on zeds with big health pool like Quarter Pounds, EDARs, and any large zeds. As well as bosses.

Its ALSO important as a reminder to NOT kill large zeds unless its a must. Do your best to ignore and target weaker zeds. Your team needs zed time in order to make the best out of it. Kill them ONLY if its a must, you'll waste too much ammo if you prioritize large zeds, making it harder for you to buy newer weapons:.

Stealing your trash zed kills is also NOT necessary, it belongs to Commando as they are the source of zed extensions. Let your team know you need those kills in order to keep it going. If you play with Swat or Firebug, they either consider moving to a different position AWAY from you, or have them target large zeds.

Some guns like Medic Assault Rifle, has no semi auto. Thats okay, just do your best to control your shots.

You have nightvision, press and hold the flashlight button to use it.

grenades can help against horde of zeds, be careful not to rage larges when throwing them. Effective against fleshpounds though, but not recommended unless you really dont need grenades (which at most times, you really dont).

You can see invisible enemies, your team can see them too if they are near you. If you die or go too far, they cant see them.

Go full auto on boss fights, always. You'll always have enough ammo for bosses.

Objective:

As a Commando, you want to target on trash zeds only. Even the weakest serve as an importance for Commando when it comes to Zed Time. Remember, the weaker they are, the easier for you to kill in order to extend zed time. Using the loadout I recommended in the picture, you should be able to get it easily this way. If not, remember to upgrade if possible so you can increase that chance. Do not target large zeds, they waste alot of ammo and this can be a problem later during the wave when you are out of ammo. Same to be said if you intend to kill weaker zeds with full auto. Remember that it doesnt take 10 bullets to kill a crawler, at most just 2-3 shots. You could very well one shot them in the head too:. Semi auto is very important to use, and if you happen to use your shots wisely, you can end the wave with good amount of ammo left. Therefore, purchasing ammo should be cheap.

Perk loadout:
High Capacity Mag: Increases your mag by 50%, you'll have more shots to give which leads to more kills/damages towards zeds. We'll be using it in this guide. The purpose of using this skill is to be more strict on headshots, it will take time but if you know how to land your shots well, you'll realize its usefulness.

Tactical Reload: It is just as good as my previous guide. However, this part of the guide I would recommend High Capacity Mag because it will involve easier large zed takedowns rather than target trash/med zeds comparing my previous guide. You can also use this on any type of zeds, just dont waste too much ammo.

Fallback: Reliable for situations when you run out of ammo, as well as able to switch faster. Its really good in my previous loadout and it can work on this one too.

Impact Rounds is reliable for easier large zed takedowns. However, you have to be even more strict with headshots since if you cant land your shots well, you will be forced to use 9mm/knife which doesnt have much damage comparing to Fallback. If you feel confident and skillful to use it, you may do so. Either will work.

Update: For more easier use, avoid using FAL and use Scar-H instead since it contains more ammo pool, allowing you to kill a good amount of zeds easier that way without pressure on wasting ammo completely. Unless you know how to use FAL very well, use that instead.

Tenacious: Reliable for survival, so you wont get killed too quickly. Giving you a chance to survive with a medic aiding you. Use this so you wont die so easily.

Prepared is almost as good as Tenacious, if you run into ammo problem you can get this. Note that increasing your ammo also means you have to buy more. Only get this if you are that confident surviving. Otherwise, I would recommend Tenacious.

Hollow Point Rounds: You do more damage with this skill. Keep noted for weaker zeds you can kill them very quickly so dont waste too much ammo on them, you have to be more strict on your shots. It also makes it easier to kill with headshots. Large zeds especially.

Eat Lead gives you more ammo, which means better chance to last Zed Time longer. However, Hollow Point Rounds allows you to kill faster to last Zed Time longer. Eat Lead helps but I would recommend Hollow Point Rounds as of this guide since you can kill larges faster that way, just make sure you are strict with your shots, thats the key of this guide.

ZED TIME: Machine Gunner:: Unquestionably the best to get in terms of extending Zed Time. Just remember you are dealing with less ammo, but the firepower will help you get kills in less shots.

ZED TIME- Tactician will only help you reload and switch weapons normally, it sounds good but thats only for defensive play. You want offensive that helps you get kills, so Machine Gunner I recommended.

Gun loadout:

FN FAL ACOG: High powered assault rifle which is known to be able to knock out large zeds if you shoot them, kills them alot faster too. The quickest way to kill them is consisting on landing headshots with all your shots. You can kill them this way and it doesnt really require all your shots. Its challenging but possible. As for weaker zeds, you may use it on them but you have to be absolutely more strict on your shots. This gun has low ammo so it can deplete VERY quickly, I would strongly recommend controlling your shots.

HMTech-401: Not the strongest assault rifle but still as reliable as the others. You can still do pretty high damage thanks to Hollow Point Rounds, and you can heal teammates. It has more ammo pool than FN FAL, so its less pressuring to use when it comes to ammo. But keep noted its firepower isnt that great comparing to FN FAL, but still reliable in its own way.

Alternate weapon: Scar-H: The Scar-H is reliable as a replacement for any weapons you use.

Want more firepower? Replace HMTech-401 with Scar-H, you can kill zeds quicker that way, especially larges.

Want more ammo? Replace FN-FAL with Scar-H, you'll get more ammo that way. Allowing you to kill more zeds before running out. Keep noted the firepower is still isnt that great comparing to FN-FAL, but at least it gives you less chance of depleting ammo so quickly.

You decide how you want to replace it, both ways help.

Unlike the previous one where you target mainly weaker zeds which would allow you to not waste too much ammo and avoid larges when possible and only attack out of self defense if they chase you. This one is reliable for any zed takedowns, but worth noting its more challenging than the other, but has bigger rewards as well that will help you out of situation. Headshot kills should be easier to land thanks to Hollow Point Rounds, this includes larges if you land all the shots. In which case you wont have some zeds chase you long enough when constantly shooting at the head. Semi auto helps if you are not good at landing shots precisely, although I wouldnt recommend using that on large zeds, always go full auto. If you are confident on your precision shots, you can see about setting it to full auto and one tap it, as it is possible to do so on weaker zeds if you know how to control your shots. Easier so you dont have to switch modes.

This loadout is also effective on boss fights as well. Just remember to focus on their weakpoints for better results.

Fallback helps if you need a extra firearm thats reliable when you are out of ammo. Impact Rounds helps for easier large zed takedowns.

Commando isnt really that hard to understand as it made out to be. When I first use it, I never truly understood the use of Commando until far later realizing that semi auto plays an important role, as well as knowing what to prioritize. I usually just shoot everything I see and kill. Later, after learning the true potential of Commando, I learn to prioritize. This perk happens to be extremely useful when dealing with weaker zeds, and you ONLY need one commando for that. Having more than one is entirely unnecessary because it only takes one to handle the situation.

This perk isnt really complex, just know how to use ammo wisely and you'll end up getting your weapons easier that way. Going full auto on every zed will not help, you have to know when to switch it up. Do this, and your team will appreciate the zed time you have given them.

With that said, I wish you the best of luck!
