A very good expansion, and for a great price.

User Rating: 9.5 | Crysis Warhead PC
The game doesn't disappoint. It's basically better than Crysis in any aspect. About the single player adventure, the new protagonist, Psycho has a much deeper/realistic personality than Nomad and the plot is less banal and better written. There is more action and less moments when you get bored from the lack of new situations, the soundtrack is GOOD and not just the same loop and graphics are better, from explosion to lighting to texture, everything looks better. The only flaw is that it is short (but this is an expansion, not a full game), and even though the vehicles are better balanced and more, it is still a pity to not be able to use flying ones through the whole game and finally that it is not true that the single player adventure is been so much optimized so that it runs with the same settings and machine, better than Crysis. It basically runs the same, maybe a bit slower. Also to mention some maybe too frequent game crashes on Vista, surely they'll be fixed with the first patch. Anyway these are all minor flaws.
The GREAT thing about this expansion is the multiplayer DVD, Crysis Wars. A lot of optimization has been done here, everything works nicer and faster, especially the big maps like Beach run much smoother than in Crysis. Bugs have been removed, vehicles handling improved, everything seems faster and better looking.
So, considering the affordable price of $30, Warhead is surely an amazing game to buy, with basically the same system requirements of Crysis and a LOT more fun and things to do. Definitely recommended to anyone with a high end pc.
