Remember how a big chunk of the game map was frozen and icy in Arkham City? The new DLC for Batman: Arkham Origins, "Cold, Cold Heart" extends that idea a bit, with the ice seemingly extending throughout the city as Penguin and Mr. Freeze terrorize the landscape on PS3, Xbox 360 and PC (but not the Wii) on April 22.
A leaked video reveals the first half hour of the DLC, the first Arkham DLC that actually adds single-player, storyline-driven gameplay instead of challenge packs and multiplayer maps. Much of it takes place in Wayne Manor as Bruce Wayne charges to the Batcave to pick up his batsuit. (Another toyetic iceproof costume shows up later.)
