Backspace, a game once in development at Fallout: New Vegas and Project Eternity developer Obsidian Entertainment, was "a mix of Mass Effect, Borderlands, and System Shock 2," according to a design document obtained by Kotaku.
The single player role-playing game was set in space and included a "simple element of time travel," the design document said. "The combat is paced similarly to Skyrim, but slightly faster since there is no concept of blocking. The easiest way to look at it is a mix of Mass Effect, Borderlands, and System Shock 2 for gameplay and setting."
Backspace was apparently planned on being developed with Bethesda and would have used The Elder Scrolls 5: Skyrim's engine. Obsidian CEO Feargus Urquhart said it "neither canceled nor greenlit" Backspace, implying that the project could be resurrected in some form.
"We had some great people work on the idea for Backspace for a bit of time and then moved them off to other projects as opportunities came up," he said. "We've been around for ten years now and have had a bunch of great ideas that we still have sitting around that we may be able to return to in the future."
Obsidian's next confirmed game, South Park: The Stick of Truth, is due out this holiday season. You can learn more about the game and the magic of farts by reading our recent hands-on impressions. You can check out more of the design document and concept art from Backspace at Kotaku.
