Don't forget that the Unlock the Achievement contest starts today at noon. You'll need to go over and register at their official website
for the contest and then it it's off to the various community sites to dig up the hidden achievements. We've already hidden the icons in different Xbox 360 related articles around the site but it will take a keen eye to find all five as they are scattered through out articles, blog posts, forums, and reviews on the site. Happy hunting.
