I guess I should mention, I bought Ground Zeroes for the PS3 and I’ll be writing about it in a few days once I’m confident that I’ve seen everything I need to. I’ve beaten the main story and the Side Ops, but haven’t unlocked what I assume is the “Deja Vu” mission. I’ve listened to most of the audio logs, too.
I haven’t synchronized the companion app, or tested nearly everything I want to though.
