Crysis creator Crytek has officially acquired Black Sea Studios, a Bulgarian company known for its historical PC real-time strategy effort Knights of Honor and the upcoming sci-fi RTS WorldShift.

Under the deal, Black Sea has been renamed Crytek Black Sea. The financial details of the buyout were not disclosed.

"Black Sea Studios already has a very qualified and experienced development team in place and will be continually expanded in capacity to join our tradition of producing highly innovative and creative games which Crytek is known for," explained Crytek managing director Avni Yerli.

It is unknown what effect the acquisition will have on the development of WorldShift, which was announced a PC exclusive. Due to piracy concerns, Crytek has stated that the company will no longer develop PC-only titles following Crysis: Warhead this fall.
