A parkouring post-apocalyptic open-world isometric RPG inspired by Thief and made in collaboration with a team including former Witching folks from CD Projekt RED is a confusing pitch (open-world RPG inspired by Thief?), but one with interesting elements. That's the broad idea of Seven [official site], which developers IMGN.PRO (them lot behind iffy Sean Bean horror Kholat) announced this morning.
At the moment they don't have much more than some words and concept art to show, and I can't imagine what the game will actually be like, but it might pique your interest.
Seven is set several centuries after an apocalyptic event, where survivors are slowly rebuilding and lust after forbidden ancient technology. Here's the official description:
"Seven is a Thief-inspired, 3D isometric RPG in which players will get a chance to freely explore the sandbox world of Vetrall Empire. Set in a 'beyond post-apocalyptic' environment the title will redefine the isometric RPG genre. The classic gameplay is totally reinvented by the protagonist's ability of free-traversing obstacles on any height, both horizontally and vertically, thanks to his parkour skills. The story created by the minds behind The Witcher 3: Wild Hunt, will be far from black and white. Lots of branching choices and difficult moral decisions resulting in surprising plot twists, are to be expected from this upcoming PC RPG fueled by Unreal Engine 4."
IMGN are probably overplaying the Witcher angle. New studio Fool's Theory, who are helping IMGN on the game, was indeed founded by a few folks from CD Projekt RED, but "the minds behind The Witcher 3" is stretching it. The only former Witcherer named (and therefore probably the most important) is Fool's Theory founder Jakub Rokosz; he was a senior quest designer on The Witcher 3, but TW3 has sixteen credited quest designers so it wasn't all on him. The project is funded and led by IMGN.
No word yet on when Seven will come out, though as the game only has concept art to show now, it'll probably be a while.
