First some info. I'm old and don't know what I'm doing most of the time. I bought COD Black Ops collection. so my wife and I could play as "couch Coop". So far out of three games we've only manged to access the zombie fight in version 2. But it gets worse, when logged in as a single player, I've tried all three games and I never encounter any enemies to shoot at or who are shooting at me. I just walk around and nothing happens. I can't help but think this is something stupid I just did but I'd really appreciate some help. Thanks in advance to anyone who would be willing to give me some info.
