Epic stated that the contract will involve multiple games and that Epic Games Japan will be equipping Square Enix with the best development tools they have available. Taka Kawasaki, territory manager of Epic Games Japan continued to speak of the strong bond between the two companies and that Epic would continue to service Square Enix for many years to come.
Unreal Engine 3, however, is still being used for development. Currently, Epic is creating Gears of War: Judgment, and mobile games for handheld devices are beginning to make use of the engine as well.
