A demo of XCOM, the wonderful turn-based strategy game by Firaxis, is on Xbox Live (1.51 GB) now. You can download it from the Xbox Marketplace if you're a Gold subscriber.
The demo is the same as the one that launched on Steam last month. It contains two levels from the single-player tutorial campaign, with both the strategy and combat layers up for messing about with.
So, you'll spend some time in your XCOM base and out in the field WHERE YOU WILL DIE THIS IS XCOM AFTER ALL.
The demo goes live on the PlayStation Store tomorrow when it updates on these shores.
