Developer and publisher City Interactive is workin on a stealth-based first-person shooter, Sniper: Ghost Warrior. 

When the democratic government of Isla Trueno is overthrown, an aggressive and hostile military command rises to power.  A highly trained covert ops unit is sent in to help the rebels accomplish objectives that only the skills of a sniper can handle.

Sniper: Ghost Warrior will be available for Xbox 360 and the PC in late Spring 2010.  

Our guess is it’s a sequel to Art of Victory.
