Sniper: Ghost Warrior tops 2m sales

City Interactive has announced more than 2m copies of Sniper: Ghost Warrior have been sold worldwide to date.

The FPS was a surprise hit when it landed in the UK last year, quickly gunning for a position in the UK All Formats Top Ten.

Sniper passed the 1m sales mark earlier this year. Back in January, City Interactive announced a sequel was on the way.

"We are all very happy that we have reached the two million units milestone," said City Interactive CEO Marek Tyminski. "This builds a strong belief we can do even better with the sequel and other upcoming releases."

Sniper: Ghost Warrior 2 is due for release in 2012.
