Spot on.
I found the game excellent before the aliens showed up. I hated the "alien spaceship" or whatever level. I also wasnt too fond of trying to dogfight in a flying bus, sorry, VTOL towards the end.
Cant say I had any technical probs at the end or anywhere really, other than my high spec Alienware being reduced to a crying baby.
I cant see much hope for a Crysis 2 if your main aim is that your off into the alien inhabited sphere to rescue your nutty squad leader. If the sequeal boasts more of the early stages of the game however then id be very happy
