Gamers looking to cash in on playing games on their Xbox 360 can now do so, as the Xbox Reward program has gone live in the United States. Complete the Rewards challenges in the specified period and you could nab yourself some prizes, depending on your level.

Level? Depending on your annual Gamerscore tier, you're eligible for different rewards, including level upgrades for future challenges. The current, Old Spice-sponsored challenge is:

The Old Spice Experience Challenge
Increase your gamerscore by 1,500 before April 12th
Rewards include: Old Spice Experience Level Upgrade, Contra Xbox LIVE Arcade games and Microsoft Points

Other prizes include copies of Fuzion Frenzy 2, t-shirts, and Old Spice branded Xbox Live gamer pictures. That Level 3 Old Spice Gamer Picture just screams hardcore. Michael McWhertor
