A number of Call of Duty 2 (Xbox 360) players have
complained that their save files become corrupted about midway through the game (after the Ridge 88 level), forcing
them to restart from the beginning. Activision claims that it's working on an update to fix the problem, but in the
meantime has suggested two makeshift solutions.
First, players should sign into their profiles prior to starting the game—IGN reports that this method works irregularly. Since that's the case, Activision recommends inputting a cheat code (posted here) that will unlock all levels. The cheat will not affect your achievements, but may make you feel less hardcore.
