I'm thinking about buying Road to Hill 30 for starters, then Earned in Blood. But I have two questions. It mentions competitive multiplayer, does anyone even play it online? And can Mac users vs Windows users? But my main question is, does it have co-op? I played a demo of one, maybe Earned in Blood, years ago on the xbox and it had co-op and I loved it. If this version has co-op it'll be an insta-buy, if not I'll consider it.
