Early access game Sub Rosa [official site] is both a blocky, physics-based FPS and a corrupt corporate simulator. You jump into its online multiplayer world, enrol with a company and start doing dirty deeds, like carrying out heists on office buildings or hunting down a limousine containing one of the game’s valuable discs.
What I’ve seen looks promising, and it’s just got even more promising, because Brendon Chung has announced he’s helping developer Cryptic Sea make the game. Chung is the chap behind Thirty Flights of Loving and Quadrilateral Cowboy. Those are good games.
