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.
Iron Storm displays a mix between World War I siege tactics, such as trench warfare and the use of mustard gas, and some World War II-style weapons such as machine guns, mortars, tanks, and rocket launchers of that era, as well as more contemporary technology such as helicopters, wireless communication, spy satellites, anti-personnel mines, and unmanned turrets.
The player character cannot take much damage before dying, and there are many enemies equipped with powerful weapons such as sniper rifles or anti-tank rifles. Several in-game glitches and vague mission objectives could often force players to replay one level multiple times before finally succeeding. Enemies also behave erratically, as seen when several attempt to walk through walls, or when the player shoots a particular enemy multiple times and yet the enemy remains unscathed.
