The controller response, especially when jumping and sprinting, is way off. Considering they've obviously worked quite hard on both of those elements being integral to gameplay, it's inexcusable.
The map isn't that great either. Not terrible, but I'm hoping it's one of the weaker ones in the game, otherwise I may just give multiplayer a miss entirely.
As much as I love the Crysis franchise and will always defend it against it's critics, if the multiplayer in this game isn't as good as Call of Duty or Battlefield, I simply won't be playing it. The impressions from this demo are that it's some way behind, though I'll have to wait for release.
