Just in case you missed it last night buried in our interview with Epic Games VP Mark Rein, the company showed off a new real-time demo at GDC 2013 this week, titled "Infiltrator." The nearly four-minute clip, showcases a sci-fi shootout created with its Unreal Engine 4, and remarkably powered by a single GeForce GTX 680. Now that we've piqued your curiosity a bit, check out this gorgeous display of futuristic espionage after the break, plus a bonus clip of the "Elemental" UE4 demo running on a PlayStation 4 dev kit in real-time.
