XCOM: Enemy Unknown is bloody brilliant, but if you don't want to take my word for it in our 9/10 review, why not try it out for yourself? A demo is now available on Xbox Live if you're a Gold subscriber, giving you the chance to sample its rock-hard action, strategic choice and controller-friendly interface.

As far as I know, a similar demo is slated to hit PSN tomorrow.

We've also got a survival guide going live later today, packed with handy hints and strategies.
