Codemasters unveils the first gameplay trailer of Colin McRae: Dirt on the 360 Marketplace. The game is several months from its June release but it already looks quite good, if not as spectacular as some of the screenshots. Update: Fixed version with better sound sync (but not perfect) online. A proper 720p version will be online tonight. Update2: 720p versions added. The quality of the original trailer on the Marketplace isn't that good to begin with, so downloading this new version isn't really necessary if you've seen the previous one.
