Iron Storm is a first-person shooter video game developed by 4X Studios and published by Wanadoo in Europe and DreamCatcher Interactive in North America. An updated version of the game called World War Zero was later released for the PlayStation 2 and Microsoft Windows. Set in an alternate history in which World War I never ended, the game takes place in 1964, the 50th year of the war, and focuses on an Allied soldier's mission to stop the Russo-Mongolian Empire from developing nuclear weapons and his later efforts to end the war.
