A new trailer from Call of Duty: Black Ops III shows off multiplayer action from the Eclipse expansion coming to the PlayStation 4 edition of the shooter sequel tomorrow, and to Windows and Xbox One next month. Here's word: "Battle through four new MP environments that take full advantage of the Black Ops III movement system, including a martial arts tournament arena, a post-apocalyptic tribal compound, a future civilian sub-orbital airport, and a military rail system suspended high above an active volcano."
