Iron Soldier

Iron Soldier is a mech simulation game played from a first-person perspective . The premise is set in the future on an industrialized Earth, where the Iron Fist Corporation (IFC) used military force to conquer governments and establish a global military dictatorship. To keep urban population in check, IFC developed a new weapon known as the Iron Soldier (IS), a 42-foot-tall piloted robot. A resistance group was formed to stop IFC and managed to capture a prototype IS unit.

The player takes on the role of a resistance member piloting the IS to overthrow IFC. The player has to fulfill mission objectives ranging from destroying specific targets, engaging enemy Iron Soldiers, defending resistance bases, or escorting convoys. There are 16 missions in total, each divided into groups of four. The player then loads the IS with weapons by placing them on the robot's shoulders, hips, and hands.

Mounting the same weapon multiple times allows a greater amount of ammo to be carried, but some weapons are restricted to specific mounts. Initially, only the robot's fist manipulator and a semi-automatic assault rifle are available, but the player can expand the arsenal by successfully completing several missions. These include hand grenades, a chainsaw, a gatling gun, a rocket launcher, a railgun, a defense shield, and cruise missiles. The player controls the IS in a three-dimensional landscape with destructible environments while fighting a variety of enemies.

The player can walk forward or backward, look, turn, and fire weapons. Mounted weapons are selected via a controller overlay. The cockpit of the IS displays several features such as a diagram of the robot indicating how much ammo is left in the currently selected weapon, a radar, and an energy bar. A mount cannot be selected if a weapon is out of ammo or no weapon is mounted, however, the player can hit buildings or enemies with the manipulator and stomp gun emplacements, houses, light tanks and trees.

Destroying warehouses and factories yields crates containing items such as ammo refills and repair kits. The player can also activate an advanced control method that decouples the robot's direction of movement from its head orientation and allows looking without changing course. If the IS is destroyed, the current mission will be incomplete, although the player will have three continues per playthrough. If a mission is failed, the player will return to the mission selection and try again without using the continue option.

Progress is manually saved after successfully completing the fourth mission in a group. There are three difficulty levels: Easy, Normal and Hard. A fourth difficulty level, Insane, can be selected by entering a cheat code at the options menu.
