As in last year's game, expect to encounter dense jungle environments, barren ice fields, Korean soldiers and plenty of flying aliens. There's no denying that this is more of the same, except here it's a more tightly woven experience with a little less freedom to explore.

With a top-end PC (although Warhead has supposedly benefited from an improved game engine, you'll still need a fairly beefy system) rest assured, developer Crytek has enhanced more than just the graphics engine.

Vehicles are more fun to drive, firefights are more intense and focused, and aliens do more than just float around you. More emphasis on the open-ended environments would have been welcome, but a more exciting (though shorter) campaign, a new multiplayer mode, and a whole bunch of new maps make Crysis Warhead an excellent expansion to one of last year's best shooters.

Crysis Warhead has good looks. As mentioned before, the game looks better than Crysis, and it runs better too. Our test machine that struggled a bit to run the original at high settings ran Warhead smoothly with the same settings. Yet as much as you may have heard about Crysis' technical prowess, you'll still be impressed when you feast your eyes on the swaying vegetation, surging water, and expressive animations. Outstanding graphics. Couldn't say more here.

We up the ante a little more by enabling DX10.

• Level Ambush
• Codepath DX10
• Anti-Aliasing 2x MSAA
• In game Quality mode Gamer

Again, similar behavior, but the GTX 295 does seem to behave quite a bit better at the uber resolution of 2560x1600. We ran the test several times to confirm this. Well, a win for Windows 7.

And for the ATI cards, again inter-operating system wise similar results, but ATI... good gawd could you please fix R4870 multi-GPU performance for this title?

Stability wise, no issues here either.
