Likewise, a complete fan-made English translation patch for the original Front Mission version was released on September 24, 2001 by the group Front Mission Translation Project.

Game progression in Front Mission is done in linear manner: watch cut-scene events, complete missions, set up wanzers during intermissions, and sortie for the next mission. The player travels to locations on a point-and-click world map. As the player progresses through the plot, new locations are revealed on the world map. Towns and cities act as intermission points where the player can organize and setup their units for the upcoming mission. Battle zones are where the missions take place, though they become inaccessible upon the completion of a mission.

In Front Mission, players use playable units called wanzers, a term for mecha derived from the German word "Wanderpanzer", or "walking tank". Wanzers differ from the typical combat unit in that it has four modular parts: body, left arm, right arm, and legs. Each part has a specific function and its own health bar. The legs parts enable movement and evasion, the arm parts are necessary to use hand and shoulder weapons, and the body part maintains the wanzer's operability. In the event the body is destroyed, the wanzer is removed from play completely. Destruction of arm and leg parts does not remove the wanzer from play, but it severely cripples its performance. While the player fights mostly wanzers, vehicles, aircraft, and mobile weapons platforms are also featured. These enemy units generally have only one part, the body, and are much stronger than wanzers themselves.

In the customization aspect of Front Mission, wanzers can be customized with a variety of parts, computers, auxiliary backpacks, and weapons. The player has full control over customizing their wanzers and can do so as long as its total weight value does not exceed its given power output. To field a wanzer in battle, it must have a complete frame of parts: body, left arm, right arm, and legs. Parts with built-in weapons in the body or arm sections can also be equipped on a wanzer. Computers improve the accuracy of the weapons equipped on the wanzer. Auxiliary backpacks and weapons are not mandatory equipment to use wanzers, but are crucial in order to progress through the video games. Auxiliary backpacks serve to give a wanzer special features during combat; they allow a wanzer to carry support items such as ammunition reloads and increase the power output of the unit, allowing it to carry heavier gear.

In terms of weapons, there are four classes of weapons: melee weapons, short-range weapons, long-range weapons, and support fire weapons. Melee weapons are weapons used at melee range and have a tendency to strike the body part of its target. Tonfas and rods are examples of melee weapons. Short-range weapons are weapons used at close range and deal damage to all parts of a target. Machine guns and shotguns are examples of short-range weapons. Long-range weapons are weapons that have long firing ranges and are ideal for avoiding counterattacks. Bazookas are examples of long-range weapons. Support fire weapons are indirect fire weapons; they can never be counterattacked, but have limited ammunition supply and minimum firing ranges. Missile launchers are examples of support fire weapons. Lastly, shields can be equipped on wanzers to absorb some of the damage taken from incoming attacks.

Front Mission has other notable features incorporated into the game. Arena is a unique feature in which the player can fight AI-controlled enemy combatants, or face another player to earn monetary rewards. Likewise, Front Mission sports a briefing feature that details basic information about the composition of enemy forces for the upcoming mission. Missions in Front Mission are traditional tactical RPG fare, ranging from destroying all enemy targets or protecting a particular allied target.
