Great expansion for fans of the original Crysis.
Warhead is SP only, the MP part is in Crysis Wars which is a separate game to install but uses the same key as Crysis Warhead. The story is helter skelter and can be hard to follow. I still don't know what incident the tape examination intermissions are referring to. Some of the events that happen conflict with those of the first game. Psycho popped in and out of the first game to help Nomad but doesn't do so in this game. If you look past the plot loopholes, you will find a game that is as fun to play as the original. Xbox 360 controller support is available on all Crysis games. A bit more variety than the original when it comes to standing around shooting the same people over and over. If you enjoyed Crysis, you will enjoy this game. I got this as part of Crysis Maximum Edition for $10 and it was money well spent.
