The Sonic & SEGA All-Stars Racing demo is now available for download from Xbox Live Marketplace.
The file's 1GB and can be queued from the Xbox website.
We don't know what's in the sampler - there's no description offered - but assume there are one or two courses and a handful of drivers to race around them.
Sonic & SEGA All-Stars Racing is a cartoon driving game clearly inspired by Mario Kart. Well-known characters have relevant special powers and the word "gloomy" has been expelled from the dictionary.
Split-screen and online multiplayer will feature in the full game, but we're not sure whether they're represented here.
