Editing Killing Floor (modification) (section)

==Perks==
Perks of the mod version of Killing Floor differs as players can unlock from feats they perform, like scoring 40 headshots, etc. You can only change perks '''''once''''' per wave, you can change perks up to 9 times per match. These perks do not level. Their descriptions are also not exact. They are as follows:

*'''Medic''': The medic perk can be unlocked by healing teammates for 1500 damage in a match. It grants:
**+100% Recharge rate with med-syringe.
**+50% Potency of medical injections.
**+5% Faster movement speed.
**-50% Damage from bloats' bile.

With those bonuses, medics are great healers and support of their team, but they do not have their own weapon, but a good a medic will use the winchester and shoot crawlers, since crawlers are very weak, and shooting them always helps your team. Another good weapon for medic is the hunting shotgun. Medics are not much used in the mod, as any class can do their job, though not as fast, but still correctly.
*'''Support''': The support perk can be unlocked by welding 2000 door hitpoints and killing 40 specimens with a Power weapon in a match. It grants:
**+10 Max carry weight. (it says +25, but it allow you to wield a hunting shotgun and a L.A.W at the same time.
**+25% Faster welding/unwelding with the welder tool.
**Double frag grenade capacity.
**+100% ammo capacity with LAW, but it actually says +25% to all power weapons, but it does not give any extra ammo to shotguns, hunting shotguns or handcannons

Support is the strongest perk in the game and the most used, after wave 7, still needing a few medic or sharpshooter, they can wield LAW and hunting shotguns, their 100% ammo bonus to LAW, makes them very good to fight off fleshpounds, they are the best class to weaken them or to kill fleshpounds alone, the best way is to fire one rocket directly at the fleshpound, switch to the hunting shotgun and finish the raged zombie. They suffer from slow speed, which is their only flaw.

*'''Sharpshooter''': The sharpshooter perk can be unlocked by scoring 40 head shots in a single match. It grants:
**+25% Increased damage with the Winchester and the Crossbow.
**+50% Greater head shot damage with all weapons.
**-75% Recoil and spread with the Winchester and the Crossbow.
**+25% max ammo capacity with Winchester and Crossbow, it does not say it, but it gives you more ammo with those guns.

Sharpshooter is the most used perk as they can be used from wave 1 to wave 9. Their winchester is very strong, the crossbow allows them to get easier head shots, and they can use hunting shotguns, with an increased efficency, due their headshot bonus, they are the best class, however, a support specialist is needed to weaken fleshpounds with rocket, or else it'll become very hard and very annoying to fight off fleshpound. Combinations of sharpshooter and fleshpound are used all the way in the game, in the first wave, it is not rare that everyone chooses to be sharpshooter.  With this perk, you can kill stalkers and crawlers from one hit with either range weapon, clots also die from one hit with the winchester. Two shots from the winchester will take care of sirens, bloats and gorefasts, with an headshot from crossbow, winchester or hunting shotgun, the sharpshooter will kill all the specimens, except the fleshpound, which is their only flaw.

*'''Commando''': The commando perk can be unlocked by killing 30 stalkers and dealing 10,000 damage with the Bullpup. It grants:
**+25% Damage with the Bullpup weapon.
**-20% Recoil and spread with the Bullpup weapon.
**+10% Faster reloading with all weapons.
**Enemy health conditions appear on the [[HUD]].
**Automatically reveals Stalkers in an AoE (Area of Effect).

The commando is actually of very little use in the game, he can kill bloats, sirens, gorefasts, crawlers, clots and stalkers, but he is best used to kill weak enemies, which is nearly nothing, it is never used against fleshpounds or scrakes, and commandos have a tough time with groups of zombies, though they can kill mobs of clots, stalkers and crawlers with ease, crawlers and stalkers being super-weak.

*'''Berserker''': The Berserker perk can be unlocked by dealing 10,000 damage with melee weapons. It grants:
**+25% damage with all melee weapons.
**+10% refire speed with all melee weapons.
**+15% movement speed adjustment when using a melee weapon.
**+15% Damage resistance to all sorts of damage.

The berserker is not a very good class, it can only be used on stalkers, clots and gorefasts, a good player can use on crawlers and bloats too, but it is not recommended, the crawler attacks rapidly and hits hard, while the bloats will explode on you. Due to the siren glitch, it is not recommended to kill her, unless you want to lose much of your health, since she will cry, even if you kill her. It has the advantage of being resistant and to save ammo, it is more useful than the commando in a way. Berserkers are best used in the first two or three waves.
