Quite an impressive deal comes to us via Amazon.com today. After just over a month in release, Guitar Hero 5 is on sale for 50% off. The deal unfortunately only applies to the Xbox 360 version (sorry Wii and PS3 rockers). We found the game impressive and gave it a very good review. Don't forget that the Guitar Hero World Tour DLC that's on sale this week is compatible with Guitar Hero 5 as well. If you're a music game fan, and haven't picked this title up yet, now's the time to nab it!
