7Days is a cancelled fantasy RPG in development around 2001 by Cauldron, a small slovak team mostly known for Soldier of Fortune: Payback, Gene Troopers and the Cabela’s Big Game Hunter series. Gameplay could have been somehow similar to The Elder Scrolls series, with action combat, underground dungeons and a fantasy open world to explore.
Unfortunately we can’t find much more online about this lost game. We know the team also worked on the cancelled Project Revolution and in 2014 Bohemia Interactive acquired Cauldron, changing their name into Bohemia Interactive Slovakia.
Thanks to Chris for the contribution!
