I think I just suffered whiplash from whomever edited that video. Yeesh. If anyone can find out what program that footage was featured on, I'd like to see it as it was originally presented.
Aside from that...this looks promising. It appears to be very much in the spirit of the PC version, but with obvious upgrades.
One of the most interesting things that stood out for me was the fact that the Alien and Predator were actually "grappling" in gameplay. That's something they could never do in the PC version, but I always felt it was needed.
Again...if anyone can find the original program...please post it. But this is looking good.
