Had it for 2 days now and haven't been able to get into a single multiplayer match. Keep getting "The connection to your session has been lost" every time I try to join a match. Wicked annoying. And apparently a problem for a large number of people based on what I found on multiple other forums.
The single player is pretty good so far but the game in my opinion is NOT Crysis, doesn't play at all like what you're used to from Crysis and Crysis Wars/Warhead. Among other changes, you can no longer go prone, only crouch which was annoying in the MP demo. It's very CoD now (not that that's a bad thing, just not a Crysis thing), leveling up in order to get better weapons, suit mods, etc. I don't think its bad, just not at all the amazing game play of Crysis/Wars that we've come to appreciate. Kind of sad really that Crytek seems to have bowed to the man on this one instead of sticking to their roots and what set them so far apart from the competition.
If I can get into a MP session some day I'll post some screen shots/vids.
Any discussion of an >XI< server for it?
