It is the 1960's, and the First World War never stopped being fought. In this alternate reality, war is the only thing powering the global financial markets and warfare is one vast continent wide trench bound slogging match. The player controls a commando sent to try to break the stale-mate. He must cross the front lines and penetrate deep into enemy territory.
World War Zero: Iron Storm is an updated version of Iron Storm. It has enhanced graphics, reworked (mostly simplified) levels, and a few additional weapons, such as a flamethrower and a mini-gun. The Windows release is based on the Playstation 2 version, and retains all the omissions it has compared to the original Iron Storm: no multiplayer, no quick save feature, no optional third-person view, and many cutscenes cut out.
