Sniper: Ghost Warrior has sold two million copies, Polish game company City Interactive has announced.

The first-person shooter went on sale in June 2010 on PC and Xbox 360. A PlayStation 3 version launched a year later.

"We are all very happy that we have reached the two million units milestone," City Interactive boss Marek Tymiński said.

"This builds a strong belief we can do even better with the sequel and other upcoming releases."

Sniper: Ghost Warrior 2, built using Crytek's game engine CryEngine 3, is due out in 2012.

City Interactive announced Sniper had sold one million copies in February 2011 - seven months after it launched.

Crazy stuff :)
The game is so bad but it keeps selling.
It's like HD version of Deca Sports.

But the crazy amount of money they made with it should allow them to establish huge development studio hopefully rising to at least Techland level (Call of Juarez/Dead Island guys)
