Killing Floor

Clot- basic zombie, grabs you.
Crawler- little bug thing. Small, weak, and goes after the person closest to death.
Gorefast- has a one arm with a blade in it, runs fast and does good damage.
Bloated- a fat slow zombie, spits poison at you and explodes into poison if you shoot it too much.
Siren- slow, but screams as a radial attack, it's scream destroys explosives.
Stalker- semi invisible, fast, does good damage, but dies easily.
Scrakes- has a chainsaw for an arm, strong, and rushes you when they get close.
Husks- long range fireball attack, strong.
Fleshbounders- biggest enemy other than boss, if you do a lot of damage to it at one time or ignore it for too long, they get mad and run really fast. Does massive damage and chases after one player at random.
Patriarch- the boss, has rocket launcher and chaingun for an arm, can go invisible, can heal himself, and has powerful melee attacks.

Sirens, clots, crawlers, stalkers, scrakes, and fleshbounders. All this talk makes me want to play. Oh boy.
Gotta start practicing on my shooting skills!! :O
