Click to view Crysis Warhead is coming with a little bundled extra: Crysis Wars, a new take on Crysis' multiplayer aspects. This trailer, made from in-game footage, shows that it's looking both nice and fast, but if they don't fix it so the Koreans don't take 1,736 bullets to kill, it'll all be for naught.
1: I don't believe it is in-game footage. There is no rail-jumping like shown and the explosion at the end is too dynamic. Some of it was in-game, but definitely not all of it.
2: The online community will not pick up until Crytek gets it through their heads that custom maps need to be downloadable in-game on-the-fly and if you don't do the work to support this the online community will never be any good.
