Ok, I didn't see this one coming: Arkham Origins will have Multiplayer.
Well, except for the Wii U version.
Warner Bros. Interactive Entertainment has revealed a new wrinkle to Batman: Arkham Origins, its prequel to Arkham Asylum and Arkham City, with the announcement of a 2 vs. 3 vs. 3 online multiplayer mode developed by Splash Damage (Brink, Enemy Territory: Quake Wars). Invisible Predator Online will pit Batman and Robin against two player-controlled teams of gun-toting henchmen, each consisting of three players, led by the competing Bat-villains Joker and Bane.
While Invisible Predator Online is set during the window of Batman: Arkham Originsí fiction, it isnít directly connected to it. Robin, for example, will not play a role in the main story, though heís a prominent figure here, but playing the solo campaign will allow you to unlock as-yet-unspecified items in multiplayer mode.
Make no mistake, this is no after-thought multiplayer mode tacked onto a solo campaign. Invisible Predator Online is shaping up to be a full-fledged, tension-filled multiplayer experience that psychologically scarred whackjobs on either side of the law will appreciate.
I've never played anything even remotely like this before, but it sounds interesting.
