I just finished Crysis Warhead. I didn't realize that it was a different game from Crysis (should have known but wasn't paying attention). Crysis Warhead is really not that different from the other Crytek games that I've played, which would have been fine, but from all the hype, I was expecting something ... I don't know ... original. But mainly I was disappointed because it was so short. Wen you spend $40 for a game, you expect more than fifteen hours of game play. Frankly, I feel a little ripped-off.
The graphics were tremendous. At the highest settings it was almost like watching a movie, but my computer couldn't quite keep up at those settings so I had to tune it down a bit.
The hovercraft is kind of neat, but I don't think it handles like a real hovercraft. There is not enough momentum in the original direction when you make sharp turn. The physics were also sloppily done on the train. If you were on the train and jumped, it seemed to move you immediately into the reference frame of the ground. That is, if you jumped straight up, you would stop moving forward relative to the ground, and the train would run away under you. It was almost impossible to jump forward.
Although the instructions contained diagrams of the controls for flying helicopters and VTOLs, there was no opportunity to do so in the game.
There is a cloaking technology to turn yourself invisible sort of like the alien in Predator. It's fun to use, but the way the game was set up wasn't very good for it. Although the game supposedly allows a stealth approach, they made it almost impossible to get through any of the scenes without setting off an alarm and bringing down the entire enemy on you --even with the cloak. You can only move a couple of dozen yards with cloak on, and the enemy soldiers are always positioned in such a way that there is always some spot with no way to get from hide to hide within the limits of the cloak. And forget taking out the problem soldier with a silenced gun. That always sets off an alarm and brings more soldiers.
My advice: wait till the game comes down to $20 or buy it in a package with Crysis. It's not worth what they are charging for it now.
