Iron Storm is a first-person shooter computer game first developed by 4X Studios and published by Wanadoo in Europe and DreamCatcher Interactive in North America. A remixed 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.
