At last, the Xbox 360 Gamerscore is no longer just for show. Microsoft’s (MSFT) Xbox Live Rewards program is now giving gamers special perks for having higher Gamerscores. Rewards are split into three tiers: Contender, Champion and Legend. Contender rewards gamers with a Gamerscore of 3,000 to 9,999 with a “special gift” during their birthday month (the prize is only worth $0.25 and is likely an Avatar item). Champion-level Gamerscores between 10,000 and 24,999 will be rewarded the special gift and 1% rebate on Xbox Live Marketplace purchases every month. And lastly, gamers with Gamerscores of 25,000 and higher qualify for Legend status, which includes everything Champion players get, but instead of a 1% rebate, they’ll get a 2% rebate every month. The Xbox Live Rewards program is only available for Gold members, so Silver members are out of luck. Now get out there and start unlocking those game achievements and boosting that Gamerscore! Xbox 360 gamers can sign up for the Xbox Live Rewards program here.
