Set during the 1961 zombie apocalypse--remember that?--Atom Zombie Smasher will have players rescuing civilians from infected cities with a team of mercenaries. And a nuclear-capable orbital battlestation. Campaigns are procedurally-generated, giving a different apocalypse each time, and it'll support co-op for up to three players.
Atom Zombie Smasher is due to be released on PC, Mac and Linux "soon." Blendo has yet to announce the price.
