Now this is probably gonna sound like a stupid question. I know that because I thought it sounded like a stupid question when a friend of mine asked me.
Okay, so here's the deal. My friend asked me if I could give him the First Strike DLC Pack by letting him log onto my user on his PS3 and then download the DLC. I told him that it wouldn't work because then he would have to be on my user to play the maps. However, he insited that some people he knew had done this and it had worked out.
I really don't think it's possible for two reasons.
1. It's Acitivison, come on!
2. If this was true, everyone would just pirate the pack, leaving poor Activision with no profit.
I can't even begin to think that Activision would make a mistake like this, and as I said, this is a stupid ass question. Still, I would appriciate your input.
