Sanctum is said to be a great mix between a Tower Defense and your typical multiplayer FPS. I wouldn't know - I haven't played it. Yet. Maybe I'll hit it now, though, since at 80% off its normal price, it's a pretty good deal! You'llLog In. Notice that other games in the franchise - the first Sanctum, DLCs as well as the isometric Sanctum TD - can also be found 80% on Steam. Just search for them.
