Two of Warner Bros. Interactive Entertainment's biggest titles this year--Batman: Arkham City and Mortal Kombat--are built on Epic Games' Unreal Engine 3 technology. The publisher is apparently pleased with the results, as today it announced a license agreement with Epic that will see the tech made available for any or all of the publisher's PC, console, and mobile games through 2014.
Under the terms of the deal, Batman developer Rocksteady Studios and Mortal Kombat maker NetherRealm Studios will use Unreal Engine 3 exclusively through 2014. Both studios should be well familiar with Epic's engine by now. Unreal Engine 3 was used by Rocksteady for the Arkham City predecessor Arkham Asylum, while the previous incarnation of NetherRealm Studios used the tech to make Midway's swan song, Mortal Kombat vs. DC Universe.
Although the pace of high-profile Unreal licensee announcements has slowed in recent years, Epic continues to push the engine. Last year, the company announced it would be bringing Unreal to iPhones and Palm Pre handhelds, and it also added support for Nvidia 3D Vision and Valve's Steamworks to the package.
