Activision’s Call of Duty Russia account as revealed that Sony Interactive Entertainment Russia is refusing to release Call of Duty: Modern Warfare 2 Campaign Remastered on PS4 at this time.
Presumably, this is because of the No Russian mission in the campaign which portrays Russians mass murdering civilians in an airport.
The Call of Duty Russia tweet has stated however that the campaign remastered will be available on Xbox One (Xbox Store) and PC (Battle.net) starting April 30.
Translated, here’s the statement:
Call of Duty: Modern Warfare 2 Campaign Remastered is a completely fictional 2009 campaign, recreated in HD quality. SIE decided not to sell the game in the Russian PS Store. We look forward to the release of the game in digital form for the PC in http://Battle.net and on Xbox consoles.
Stay tuned for updates.
