Former The Witcher 2 senior producer Tomasz Gop has unveiled his latest project - a new multiplatform RPG due for release on PC, PlayStation 3 and Xbox 360 in 2013.

As revealed by DigitalSpy, the game, currently codenamed Project RPG, is set 1000 years after the death of a God, whose enormous corpse forms a mountain that has divided the world in two. Each half has its own distinct philosophy and you'll have to pick a side early on in the game.

The combat system is apparently influenced by the likes of Dark Souls, Kingdoms of Amalur and Batman: Arkham City, with enemies designed so that players recognise them by their behaviour rather than their appearance.

It's being developed at German studio Deck13, with Sniper: Ghost Warrior publisher City Interactive pulling the strings.

That's all we know for now, but the rather handsome piece of concept art below should whet your appetite for more.
