Facebook has built a world-class, murderous, Doom-playing AI

Researchers from Facebook have built a highly efficient piece of artificial intelligence (AI), programmed to slaughter anything in its path. A team from the social network blasted its way to glory this week in a contest to build programs capable of autonomously playing the classic first-person shooter game. Called VizDoom, it's an irreverent test of skill for AI researchers, focused on eight-player deathmatches. Think your software is smart? AI, of wildly varying levels of sophistication, has been in games since the earliest days of the medium.
