An exploit related to code in the hardcore mode of Borderlands 2 for Xbox 360 is making the rounds and developer Gearbox Software is warning players about it and how to avoid it altogether. The problem apparently is not related to other versions of the game on PC and PS3. The exploit is supposedly tied to the hardcore game mode known as "Graveyard mode that was left in the game code by Gearbox Software. It apparently wipes the progress of players who come in contact with other players, much like a virus.
Gearbox addressed the issue in a recent forum post:
"Recently a few users have begun violating the Xbox Live Code of Conduct by using an external application to maliciously disrupt the experience and sabotage characters of legitimate Borderlands 2 players on Xbox 360," Gearbox wrote on its forum. "After extensive internal testing, an update to prevent this disruption has been submitted to Microsoft and will be released as soon as possible. Until then, concerned Xbox 360 players of Borderlands 2 should consider playing online with trusted individuals in non-public sessions."
Gearbox also notes in the same thread that there is a way for players to avoid being "infected" and not have their progress destroyed:
"We also advise that before ceasing play, users always select ‘Save and Quit’ from within the pause menu while their character is alive," the post continues."If after the death of their character players find themselves at the main menu of Borderlands 2 instead of respawning in-game, be sure to immediately select "Continue" to resume playing as that character. We ask that players report any suspicious behavior in Borderlands 2 to firstname.lastname@example.org and provide as much details and documentation of their disrupted experience as possible to assist us in our investigation."
