Microsoft has announced the introduction of a new rewards program for Xbox Live Arcade called Avatar Famestars.

Bling out your Xbox Live avatar.

The program will allow players to earn rewards for their avatars and accumulate “Famestar points” by completing challenges across multiple XBLA titles.

According to Microsoft, the Avatar Famestars program will include weekly and one-time challenges, and provide players with avatar rewards such as new outfits and items. Players will be able to carry these rewards over from one game to the next.

Avatar Famestars will launch this week with the release of Iron Galaxy’s Wreckateer, part of Microsoft’s Summer or Arcade annual promotion.

The avatar rewards program will also be added to Full House Poker and A World of Keflings, as well as upcoming titles including Fire Pro Wrestling, Homerun Stars and Avatar Motocross Madness.
