Level Class Perks – Killing Floor 2

Level Class Perks

Level Class PerksThere are a number of ways in which the leveling system has changed since Killing Floor, and chief among them are Level Class Perks. Here are some of the changes in playstyle you should keep in mind if you want to level up faster!

The leveling system in Killing Floor 2, is interesting at the least. Thanks to its allowance for off-perk leveling - such as being able to level a certain perk while using a specific weapon, even if you aren't currently using that perk. Each class currently has 25 levels while in Early Access. Each time you gain a level, your stats are increased by a small percentage, and after each 5-level increment, you choose between two different level perks (see Basic Class Overview – Killing Floor 2 for a look at the different perk rewards).

To Level Class Perks in a particular class in Killing Floor, you had to use one of the class's corresponding weapons to do a certain amount of cumulative damage against enemy Zeds - and there would also be an additional requirement per class that you would also need to farm (for example door-welding, amount of healing done, etc.). These were mostly an annoyance, silliness done in between waves when you were just waiting for the seconds to tick down and the next wave to start.

In Killing Floor 2, this process has been streamlined so that you receive XP from doing class-related things (like healing), but it is not a requirement in order to level up. This is a huge relief for those of us unimpressed with the necessity of doing stupid things (like weld the door, unweld the door, weld the door, unweld the door) and the scarcity of enemies we needed to kill a certain number of creatures.

The fastest way to level up any perk is to simply focus on using perk weapons to kill Zeds. 

Level Class Perks - XP Required Per Level and Per Zed

Below is a list of XP required for each level, regardless of class. You gain XP in the perk associated with the weapon you are using, not with what class you currently are.

Level Class Perks - XP Per Level


Note: XP is not cumulative, so after you have gained 2640 XP to get to Level 1, you then need to gain 2917 XP to get to level 2, not 277.

When you do perk-specific actions, you gain extra XP. This chart below shows how much XP you get on top of the base XP reward for killing a particular Zed:

Level Class Perks - XP Gains per kill

Each Zed rewards the player with a different amount of XP. Currently, all players who shoot a Zed even once will be rewarded with full XP gain for that Zed. 

Note: The amount of Dosh you receive is dependent on the amount of damage you did to that particular Zed. 

Below is a chart of the amount of XP per Zed, including the Early Access boss, Hans Volter:

As you can see, you are likely to gain more XP by doing a Normal campaign and beating Hans in Normal than you would by playing through a Hard mode and failing partway through.

Level Class Perks - Leveling Tips for Each Class


  • Make sure you're using a Berserker weapon! The Katana is now an off-perk weapon which means you have 0 XP gain while using it. (Each of the main classes will be broken into two distinct paths - the Katana is now one of the weapons for the future melee Dragon class). 
  • It is faster and easier to rack up Berserker kills by running around with melee weapons rather than killing them from a distance with the Nail Gun.
  • I highly suggest getting to Level 10 and choosing the perk that keeps Clots from grabbing onto you, which will make diving into mobs much safer for you. 


  • Shoot everything. Commandos have a large number of bullets at their disposal and they have a faster reload than other classes. Even if you don't take their heads off immediately, you will be able to fire a bullet into the next body probably faster than anybody else. 
  • Single-fire will still get you further than fully auto. Your guns are very accurate and you benefit from a targeting sight where others rely solely on iron sights. Don't waste more bullets than you need to trying to up your XP gain. 


  • The more HP other players have lost, the more XP you gain from healing them. Letting them get closer to death may not make you the best medic, but it will allow you to get the most XP out of doing your job.
  • Try to shoot everything at least once. You are able to carry a number of different weapons, many of them with a huge supply of bullets. You only need one for each.


  • Remember to use your extra penetration with shotguns to full effect and shoot where you have more than one target. This has the double bonus of being exactly what you should do as a good support specialist, and also what will get you the most XP as well. 
  • Even when not a Support, an AA-12 is a beautiful weapon that deals high damage in a very short period of time. You can carry this weapon as any other class to help you get out of a tight spot, and it will level up your Support perk when you do so.

Please note that many of the above strategies are listed because they will get you the highest XP gain the fastest - not what will make you a better player. Some of these should be considered only when you are playing on your own. Don't be a troll, there are enough of those in World of Warcraft.
