When it's a heavy "pea souper" fog, I like to go for a walk, take in the silence... in a grave yard, during a zombie apocalypse. What are you nuts?

Zaph takes the kill shot with the Barrett M95; say good-bye to the Tall-Boy and to Craig's hearing.
Don't bother reading this. Read Penny Arcade instead, they know what they're doing, unlike me!
Complete the level with all "Cleaners" (that's what they call the characters here), alive. Shouldn't be too hard - with the difficulty level set to novice ;)
Craig has wisely chosen the gun that can deliver 280 points of damage with one shot, with about 5 rounds in the mag. I'll take the 30 rounds in a clip thanks, 12 points of well placed damage is all you need!
