So I popped on to Halo 4 for the first time in about a year, and I suddenly got 25 achievements worth 680 gamerscore. When I went to check I found it had given me all the DLC acheevos. This happen to anyone else?
Old news, buddy. These were glitched and as a fix they decided to give them to everyone who has and played on the DLC maps.
i still need a few of them from the ricochet mode ;(
- some from the campaign
