Hot on the heels of Crysis comes its capable standalone expansion pack. Warhead is much more linear than its predecessor, but punches the action and set pieces up to ridiculous levels. It's much more OTT, riotous and arguably fun than the original - and somehow manages to both look and run better on a wider range of machines. Plus, we much prefer the hilariously cliched British protagonist. Psycho is a bit of a ledge.
If you don't own either of these games, you can download the double pack for £6.24, which will save you a few pence. It's probably worth doing just so you can answer one simple question about your rig.
Can it run Crysis?
