Need to slide under a trap or obstacle in Resident Evil 6?
All you need to do to slide is hold forward, press and hold the action button (A on 360, X on PS3) or click and hold the left analog stick to start running, and then  finally to slide just press the aim button (LT on 360, L2 on PS3).
Nothing to it right? Aren’t you glad the game came with that nice book? Oh wait..
