SEGA have released a free demo for their sci-fi shooter Vanquish on Xbox Live and PSN.

The demo features a tutorial and several combat encounters designed to give prospective purchasers a good handle on the finished product.

We've been playing a fair bit of early code in the office this week - you can read more about our experiences in our hands-on article.

Xbox gamers can start their demo download from this Xbox Live page, PS3 users will need to log into PSN to get the ball rolling.

Vanquish is due for release 22 October this year.
