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
