I finally tried to start playing Mothership Zeta, but it "freezes" (I use quotes because one of the aliens moves a little bit) on the opening screen after getting beamed up. I can't save or load from the pause screen, and only the x button (ps3) gets any response (just a jumping sound). I've downloaded it twice. I've re-loaded from different saves. I've dropped all my weapons from other DLC- If anyone has any advice on how to get this to work I'd really appreciate it.
The same happened to me (I'm PS3 too) All I did was make a save before beaming up. When it froze again just reload to the save you just made and try again. It worked first time after doing that :goodjob:
