Infinity Blade: Dungeons is being developed by Epic's newly unveiled Impossible Studios.
The iOS title is a touch-based action role-playing game, developed using Unreal Engine 3.
The game was announced earlier this year at GDC.
The game, which is led by studio director Sean Dunn, was conceived at Epic’s Cary branch, and is being developed in collaboration with Epic and Chair at Impossible’s offices in Maryland.
In June, Epic’s co-founder Mark Rein tweeted that Infinity Blade had become its most profitable franchise ever “in terms of man years invested versus revenue”. The franchise has earned over $30m since its first release in December 2010.
Infinity Blade: Dungeons is due to release on the Apple App Store later this year.
