Those of you who enjoyed Metro 2033 and downloaded the Ranger Pack DLC have probably run into achievement bugs and glitches that create problems while trying to unlock achievements. Sadly a patch that was included in the Ranger Pack DLC has caused tons of problems to the original game and has hindered many achievement hunters in their quest for all the achievements in the game. THQ has known about the problem for over 3 weeks and are still working on a fix. Don’t worry guys, you just need to be patient.
THQ recently released this statement regarding the work on the problem.
“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 realise 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.”
Remember, the game itself is still working perfectly fine; it is just that ranger pack that is causing all the problems. If you are thinking about buying the game, I would suggest to simply avoid buying that DLC until a later date when the problem is fixed.
