They praised improved visuals that run better and better AI and adding the team deathmatch mode. Also like how the action was intense and focused. But they thought that the game was to linear at times and also the AI still has a few remaining problems.
The review mostly mentioned great things about the game such as improved vehicle controls and better AI, it's a nice read and I really can't wait to get this game.
And to anyone who wants to get Crysis: Warhead I would suggest getting the original Crysis as well especially if you are interested in the single player campaigns of the games.
Oh and for those that don't know the original Crysis got a 9.5/10 at Gamespot.
