For a free promotional game, I found "Doritos Crash Course" to be surprisingly entertaining, and it looks like Xbox Live is getting sequel. According to a recent tweet via Xbox's Major Nelson, "Doritos Crash Course 2" will be available for free this week.
Much like the first game, "Doritos Crash Course 2" will see Xbox avatars stumbling through a crazy obstacle course in the vein of Wipeout. Leaderboards and "asynchronous game clips" will allow you to compete with friends online, and up to four can partake in local multiplayer.
The game introduces 4 brand new worlds filled with all of the ridiculous obstacles and traps you'd expect. Players will compete for medals and track down stars to unlock new courses, power-ups and vanity items.
If you enjoyed the first "Doritos Crash Course" even a little bit, the sequel is definitely worth a look when it lands in the Xbox Marketplace on May 8th -- It is a completely free download, after all.
