A demo for Ruffian's Crackdown 2 is set to hit Xbox Live today.

The Gold members only demo will cost you 1.07GB of disk space and will allow you to start earning Achievements before the game's release.

As we told you last week, the demo will feature ten Achievements worth 10G each but you'll only be able to add them to your Gamerscore when you buy the full game.

We brought descriptions of a few of Crackdown 2's Achievements so that you can start visualising success well in advance.

Have a look at the game's opening cutscene from earlier this month so that you can get up to speed on the premise if you're not already.
