City Interactive, which recently nabbed Stuart Black, is apparently working on a new shooter using Unreal Engine 3.
At the end of November, it was announced Black would be making a WWII shooter for the studio, and in addition to that, the studio was already working on two other FPS games, using Crytek's CryENGINE3.
So, that makes four FPS games coming from the developer, with Eurogamer being told "it could be that one of them is Sniper 2".
Sniper: Ghost Warrior is out now for PC and Xbox 360, and will see a Q1 2011 release on PS3.
That's a lot of shooters.
