Killing Floor - still worth getting?

[LiNuX]

The only thing L4D and KF have in common is that you get to shoot and Melee zombies to death. In KF however, you can't become an infected. There are perks here that basically act like a pokemon type...don't have a better way of putting it. You know, like water type with the water attacks and fire type with the fire. This has sharpshooter and firebug etc. Sharpshooters do a lot more damage when you hit the head, you can one shot one of the high level infecteds with a Bow. Firebug gets a huge discount on the flame thrower (L4D2 needs a flame thrower)

Both games have their own set of advantage over the other. SO I wouldn't call KF the poor man's L4D. Although the price suggests it.
