I'm bad at FPS games. Ask Stigg, he has played Left 4 Dead with me. Once. I think I may have shot the wall and the floor more than any monsters and while everybody else is graceful like a gazelle jumping between obstacles I tend to faceplant and slide down. This, however, may make me try at least. I've occasionally been following this (And Titanfall) and both are starting to look very, very tasty.
