I honestly hope that the bit where the acid blood is hurting the player is from the campaign, because it looks like it DOES a shitload of damage. I really hope I'm right on this being from single player, because I love it.
Everything else in this trailer is actually ok at best. Different kinds of Xenomorphs doing different types of work? I'll buy that, as long as they actually show me that these xenos are doing work that normal xenomorphs can't afford to do. If that happens, I'll be happy.
Still going to have to explain all the other continuity issues though.
Pulse Rifle just sounds like a joke. Pitchford looks like he is about to have a heart attack every time he wants to f**king geek out. Please Pitchford, you don't need to f**king explain what these bastards are, or anything in the game, the same goes for everyone. Just talk about the game as if you're talking to the fans with no bullshit, because in all honesty these will be the MAJORITY of people that will buy this game.
