Tim Sweeney from Epic Games showed up at tonight's PlayStation Meeting
to reveal that Unreal Engine 3 works on the NGP
-- which shouldn't be much of a surprise, given that the device was shown running PS3 games, and UE3 runs on phones
Speaking of phones, the game demonstrated was Dungeon Defenders
, which is currently available for Android and iPhone. Sweeney also showed an updated version of the "Epic Citadel
" tech demo.
