Play Station 3 Online Coop?

So I play games with this girl pretty much every single night. She lives 2000 miles away so videogames are pretty much all we've got:/ But we're tired of COD, Minecraft, etc. So I was wondering if you guys know any fun online coop games? Expesually online coop campaigns. I think I saw Dead Space 3 has it, but is it good? We like pretty much any games, but are mostly into arcade, action and scary games… Thanks!
