Remember Warren Spector? He's quite possibly the inventor of the immersive sim subgenre. If you don't remember him, I'm sure you'll remember his legacy: Ultima VI, Thief, Deus Ex, System Shock, etc. If any of those names fill you with fondness, then I have some good news for you. Warren Spector is back, and at the helm of a brand new game that's cut from the same cloth of all of those gems. Underworld Ascendant has come to put the immersive sim back on the map.
