haha yeah, trying to manually aim while boosting or falling is a nightmare though. it's pretty fun, but I've only really been playing multiplayer because single player is far too MMMURRRICAA
I've picked up a few amusing things:
spray an enemy with bullets, then run inside and shoot a semtex ball at the inside of the door frame - if they chase you, it'll be too late by the time they see it
when trying for a stomp, hold the crouch button and you'll land prone - I've done it a few times and seen people aiming up and spinning around in circles wondering where the fuck I went
also, is it just me or do threat grenades fucking suck in multiplayer? compared to single player at least.
