Trusted Reviews writes: "If games were sold like detergents, Crysis Warhead would have been called Crysis Concentrated. This is fundamentally a heavily focussed, super-strength version of its predecessor that proves that a little Crysis can actually go further than a lot.
It's a Crysis without all the dull bits. There is less time racing around vast environments, not being 100% sure how to get to the next objectives, while half the North Korean army (not to mention several irritating helicopters) hound you without mercy. There is less time where you feel like you're suddenly stuck in a lesser alien-blasting FPS while dull extra-terrestrial entities bob around. This is still a spectacular Crysis, still a bombastic and hugely macho Crysis, but it's also a more refined and exhilarating Crysis this time round."
