It looks like we may never be able to trust the legitimacy of an impressive Game Center account ever again, thanks to this new jailbreak tweak from Ingmar Stein.

Aptly named Overachiever, Stein’s new tweak allows users to earn Game Center achievements without actually playing the required games or levels…

There’s really not much to the package. Once installed, simply pop into your Settings app and select the games that you want to acquire achievements on. It’s worth noting that earned achievements aren’t reversible. So make sure you choose your games wisely.

After you’ve selected the titles, launch the Game Center application and sign in. This is where Overachiever does its magic. It fills in all of the missing achievements of the games you chose in the Settings app, turning you into the king of Angry Birds (or whatever games you selected).

Overachiever isn’t for everyone, and it certainly isn’t a must-have tweak. But if you have some empty spots in your Game Center profile that you want filled, it might be worth trying. You can grab Overachiever from the BigBoss repo in Cydia, for free.

What do you think of Overachiever?
