THQ has requested a little 'patience' from Metro 2033 players who have encountered a problem with the the recent Ranger Pack DLC.
The DLC interferes with the games Achievement tracking and prevents players from unlocking achievements, while some have reported this only affects the DLC, others have said the bug affects all the Achievements in the game.
THQ has responded and said they are fully aware of the issue and are attempting to pinpoint the problem, all they ask for is a little patience.
"We understand some people are still experiencing issues with achievements unlocking in the Metro 2033 Ranger Pack DLC. We are currently working with Microsoft to ascertain whether this is due to a code related issue with the DLC itself, or an error in the Marketplace process whereby the DLC was added to Xbox LIVE Marketplace before the new achievement data was added - this exact issue has happened to other games in the past, but we need to be sure that this is what's happening here. We realize this is frustrating for those of you who have been waiting to enjoy the Ranger Pack DLC, and we ask for your patience as we try to pinpoint the exact issue and solution."
