Double Fine’s told Kotaku that it’ll bring in a horde mode for Iron Brigade, nee Trenched, through a new DLC pack. Called Rise of the Martian Bear, a new campaign of missions will also be included. No date or price for the DLC as yet, though. Nor is there still a date for the European release of the game, which has been held back due to a trademark dispute. It was due to release in September, as announced at gamescom.
