As of 12 PM EST, the Unlock the Achievement contest will begin! Once you are registered at the Unlock the Achievement site, you can start searching for those achievements. 5 of them have been hidden here at Co-Optimus.com, and among 41 other sites participating is our partner, Evil Avatar. In addition to earning cool prizes, such as 360 games, the contest benefits the St. Jude Children's Research Hospital. Good luck with your search, and have fun!
