ARRRGGHHH this F****ING game!!
I've just sat over the last two days playing it on realistic all on my own, no co-op whatsoever and no playing as Knight yet either... "just incase". Beat the game..... NOTHING!
I've checked all levels and scenes and all are ticked as realistic. Was hoping I'd be ok as I got the Extreme Hunter achievement no problem.
WTF have they done with this game!? God I wish I lived nearer their offices!
