Gun Game for me 18 or 3X6, so long as i don't get stuck on a gun, if i do then i just run around like an asshat knifing people and pissing them off.
I enjoy the one in the chamber, I only wish they would increase the death count, I usually don't hit my stride till the 2nd or 3rd death. Don't forget when you are eliminated to select a player you think will get kills. You get 300XP for every kill they get.
All or nothing, if you like being an infected you will enjoy this one. Knife and throwing knife only to start, Specialist perks get you scavenger on your 1st kill enabling you to load your pistol and replenish you throwing knife.
