I have been authorized by TWI to post this information here, so here it is:
Level 6 Perk Information
Field Medic
Requirements: Attempt to heal other players but in doing so miss and waste time 'reloading' your unused syringe, resulting in sub-par supporting of other players and general failure of the team (perform for 10,000HP missed).
Bonus: Spawn with a dart gun that must be fired some distance to the right of a player in order to be effective. Temporarily blinds and slows down target player allowing you to run ahead and steal their kills. Heals specimens.
Support Specialist
Requirements: Blow up 1000 doors with grenades in the same match.
Bonus: Spawn with a support bra. Offers limited protection from breast-grabbing attacks.
Sharpshooter
Requirements: Headshot a Scarke.
Bonus: Ability to fire a helicopter out of the 9mm. This helicopter can be entered and piloted, however in order to not make this overpowered it must be fired towards the ground within a 10 metre radius, and it explodes on contact with the map, or another player. If it hits a specimen they board it and gain access to the redeemer.
Commando
Requirements: Kill 5,000,000 stalkers feeding off the corpse of a fallen team mate.
Bonus: Spawn with laser goggles, allowing you to see in the dark. However, when wearing them you are permanently blinded and have your health reduced by 10 points for every second that you wear them.
Berserker
Requirements: Successfully kill 10 scrakes with the katana without making them glitch (freeze).
Bonus: Spawn with a chainsaw. However, this is no ordinary chainsaw. This chainsaw is of the petrol (gas) type yet it has an electric switch, and will run forever on an empty tank of fuel. It can also never overheat and doesn't require chain oil, or chain tightening. You can use this to crouch in doorways, tape your left mouse button down, and go make yourself some food or fap furiously to a review that favours Killing Floor over Left 4 Dead.
Firebug
Requirements: Cause 1,000,000HP damage to team mates with your flamethrower. Damage is discounted if you get kicked from the game, and completely reset if you get banned.
Bonus: You can no longer set yourself on fire, only to balance this out the recoil is 500% more powerful and firing more than 10ml of ammunition causes the flamethrower to overheat and explode, killing you.
