It seems you can't scratch your arse without another Crysis trailer hopping onto the internet, and a latest one we've tripped over takes us on a brief tour of what apparently is the alien mothership, with zero-G stuff occurring. It's very dark in the mothership - we're reminded of Alien/Aliens.
Anyway, the trailer's up on YouTube. It's possible you've seen it before, before you start ya moaning.
Crytek boss Cevat Yerli has promised that confrontation with Crysis' alien menace will result in major shocks and scares. "...the first time you see them you'll shit your pants!" he exclaimed, adding, "Imagine the last good horror game you played. This is going to be like that, but every time you'll play it'll be different".
