In development at Necrophone Games, Jazzpunk is described as "a comedy adventure set in an alternate reality Cold War World, plagued with corporate espionage, CyberCrime, and sentient martinis." Its developers claim that the game is largely based on the spoof comedy films of yesteryear and features open-world exploration. There's no mention of the trailer's ill-fated pocket pigeon, but we're sure that will all be explained when the game makes its February 7 Steam debut.
