Just saw the video, and I can confirm without the slightest doubt in my mind, my money is already spent on this game. I'm glad to see they somehow found a way to be innovative and actually upgrade the game is areas other than the graphics. Speaking of which, awesome stuff. I hope they have a survival type mode like in the first one, and of course all the other multiplayer match types from the second.
I wonder if they will keep the humans separate with marines and corporates. I loved using Ichura (However you spell her name) with the sniper rifle. Problem is they did a good job with the 2nd version so to create a lot of new ideas would be difficult. I think if they add elements from 1 and 2, throw in a bunch of maps, I would be happy.
