Microsoft has launched a new Xbox LIVE Rewards scheme entitling players who have passed certain Gamerscore milestones to additional discounts on Xbox LIVE Marketplace. If you've unlocked between 3,000-9,999 Gamerscore on your Xbox LIVE profile, you'll be sent a "Special Gift" on your birthday. Don't get too excited, though: according to Microsoft, the gift only holds a value of 15p. However, if you've earned between 10,000-24,999 Gamerscore, you'll receive both the birthday gift and be entitled to a 1% rebate on all purchases from Xbox LIVE Marketplace every month. Players who have unlocked 25,000+ Gamerscore, meanwhile, will earn a 2% rebate on all purchases every month and the birthday gift. To sign up for the offer, you simply need to activate the Xbox LIVE Rewards scheme on your Xbox LIVE Gold account. Most Xbox LIVE Marketplace purchases qualify for the rebate, including Games on Demand, Arcade Games, Game Add-ons and Avatar items, but purchases of Microsoft Points or Xbox LIVE memberships are excluded. Players can also earn free Microsoft Points by taking part in surveys and buying items on Xbox LIVE Marketplace.
