Some of the developers that worked on BioShock revealed their new game today. Slated for release on PC (via Steam) in 2017 and on consoles in 2018, this is City of Brass.

City of Brass is a first-person roguelite where you play as a "cunning thief" that is trying to reach a big ol' treasure at the heart of a city. You have a blade, a whip, and plenty of traps to overcome on your adventure.
City of Brass has eternal replayability, designed to encourage combinative gameplay within an ever-changing, carefully optimized cityscape. Gamers must learn to manipulate every system if they are to survive, moving swiftly and deftly through each level, balancing the need for loot with the absolute requirement to escape within the time limit.
