Over the last few days, players have been reporting connectivity issues in Borderlands: Game of the Year Edition . The issue prevents players from being able to join their friends in co-op games, something that's a major part of the game's functionality. To thank players for their patience while they investigate the issues, Gearbox is offering five Gold Keys for players to redeem in the game in the meantime.Players who have tried redeeming the codes via the game's website have been encountering error messages, so make sure you redeem them in the game itself, where there have been no issues. As soon as Gearbox updates players on the connectivity issues, we'll be sure to let you know.We've got the full list of Borderlands: Game of the Year Edition achievements - check the list for guides to unlocking them.
