The latest Call of Duty game has been hit by thousands of negative reviews over its portrayal of Russia.
The 16th major title in the series has largely been praised by critics.
But Russian media and users on the review site Metacritic claimed the game was trying to rewrite history and promote anti-Russian propaganda.
A spokesman for Activision Blizzard declined to comment on the user reviews but the company said the storylines were fictional.
In a recent blog, the company said the game did not represent real-world events.
