The upcoming Kinect-controlled Xbox Live Arcade game, Wreckateer, will be the first game to feature the Avatar Famestars feature, which is a meta-game in which players earn Famestar Points toward earning rewards.
Select games will feature Avatar Famestars, and all of them, like Achievements, contribute to a single score. Rewards will be given out based on total Famestar Points.
It isn't just new games like Wreckateer that will have the feature. Some older games like Full House Poker and A World of Keflings will be retro-fitted with the feature. Upcoming games that will have Avatar Famestars include Fire Pro Wrestling, Homerun Stars and Avatar Motocross Madness.
Wreckateer is an Angry Birds-style casual game that will be debuting on the 24th July.
