[Update: There are no codes left.]
Gamers who want to check out the Xbox 360 version of the Mass Effect 3 demo a few days early can do so via a new Facebook app.
In the app, players get three attempts to decode a sequence by clicking on a series of four icons. A failed attempt will lock the player out of the game for 120 minutes, but a successful attempt will earn them a code redeemable for an Xbox 360 Avatar item or the demo.
For those gamers who are patient or simply don’t want to deal with Facebook, the Mass Effect 3 demo will be available on all platforms on the 14th February.
