Turborilla promises to release a free beta version of their action motocross racing game "Mad Skills Motocross" when the number of fans on Facebook reaches 1001. The small, independent game developer whishes to increase their presence on social networks and are rewarding their fans accordingly. After the beta has been released Turborilla has another ace up their sleeve and will announce an interesting concept involving a formula and the number of Facebook fans.

Mad Skills Motocross is a sidescrolling motocross game that reminds of the golden days of gaming while also utilizing high-tech features. The game sports neural networks for the AI and precise physical simulations of motocross bikes and riders. It can be played on Windows, Macintosh and Linux.

One of the testers of an early development version had this to say: "I have to really say, I really enjoy it. It's got quite a bit of replay factor even in its current form. The later tracks are really pretty sweet. The arcade mode is just straight fun."

Now Facebook users can also enjoy an early peek at Mad Skills Motocross. All you have to do is go to the fan page, and choose to become a fan. As soon as 1001 users have become fans, Mad Skills Motocross Beta will be released to all of them for free.
