It's like Magicka in space, and everyone's invited
Helldivers is a game that admittedly went under my radar literally until the moment we showed it off on Dtoid.TV. Then I found out it's being developed by the same folks who brought us Magicka. Then I found out, when it comes out for PS3, PS4, and the PS Vita this summer, Helldivers will allow you to play with friends locally, online, and across all three platforms in any combination. I am super down for this title. It seems our cooperative options are narrowing these days, and that's really the only kind of multiplayer I care about.
