Much of the same fun Crysis offered, but with a little more polish.
Linear games can bore you to tears but Warhead offers a great blend of action and atmosphere with enough potential to replay. However, one can't help but feel the story has been told and so when Crytek try another sub-story within the original...well it just doesn't work.
The cut scenes are quite often long-winded and 'cheesy' but I'll forgive that because the environments looked better than the original and the Aliens were a little more fun to actually play against. Crytek successfully polished the details but I would have preferred something different. We already know how the good guys got along so maybe Warhead should have focused on you playing as one of the scientists or perhaps the bad General?
Graphics:
Probably the best overall graphics around (Farcry 2 still takes the foliage crown)
Sound:
Very good - great work on the surround and stereo headphones work well
Gameplay
Fun game. Cool environments and some new weapons. The story is a little sad compared to the first Crysis. Much too short for a fully priced game which offers much of the same.
