Blend Games is in a giving mood once again. This time, we've got one free copy of Guitar Hero 5 for the Xbox 360 to send out to a lucky reader.

The giveaway is sponsored by Coca-Cola, who's giving away 50 video game prizes a day on the My Coke Rewards website between now and December 31st. Their prizes include Guitar Hero 5, DJ Hero, and Xbox 360 consoles.

You'll need a My Coke Rewards account for a chance to win their giveaways. For our free copy of Guitar Hero 5, though, you'll just need Twitter. Full rules are below.

Contest Rules
Log in to your twitter account, follow @cinemablend and then tweet this: "@cinemablend Enter me to win Guitar Hero 5 for the Xbox 360!" The two winners will be selected at random. Entries will be accepted until 5 PM on Thursday, December 17th. The winners will then be contacted and the game will be mailed to the addresses they provide.
