SINGLE PLAYER
1. No intro movie, cuts straight to sub.
2. Apparently there are supposed to be something like 8 guys with me when the game starts... I see none.
3. I get to a point down the corridor where I cannot progress, presumably because of lack of said people (mentions something about helping with a valve).
MULTIPLAYER
4. Try to change a class, game crashes to desktop.
5. Try to join a game (ranked and otherwise), and it also crashes.

Long story short, the game is completely unplayable.
I have found no record of any of these bugs on steam forums and/or official forums (apologies if I've missed a relevant thread). I verify the integrity, and apparently it's all good. All my drivers are up to date, etc. etc. etc.

Bought through steam, Specs are: Windows 7 Professional (64), ATI Radeon HD 4800, Intel Core 2 Quad @ 2.4gHz, 4 gig RAM.

Edit: Forgot to mention that I also activated the Crysis 2 Limited Edition Bundle, should that make a difference to the 4th issue.
