It occurs during the events leading up to A New Hope. The game's plot is that of the Galactic Civil War and the construction of the Death Star. Darth Vader becomes a special TIE fighter unit in space), while others can be used only on land or only in space (a land-only Hero will remain on board a landing craft or command ship during space battles and have no use of their special abilities). Some characters can be used in both land and space battles, (e.g. For example, Obi-Wan Kenobi, Emperor Palpatine, and Darth Vader can use the Force. Each Hero is a single, moderately powerful unit with special abilities. When playing against the computer, the player can accelerate time or pause time on both the galactic and skirmish maps.ДЄll modes also make use of important Star Wars characters, such as Darth Vader, as Heroes. After the battle, the galactic day timer resumes. When a battle occurs, galactic time is paused while the battle is waged. Days on the galactic map pass continually. Maps can support two, three, or four players, and the difficulty can be switched between easy, medium or hard.ДЄll modes are played in real time. Skirmish battles require the least time investment, so it is better suited toward casual players. The player can build more buildings and defenses, and the space station can also be upgraded to better defend itself without requiring the player to leave ships behind to defend it. The player can advance in technology levels to access more powerful ships as the player gains more money. The player buys land or space units to attack the enemy with until the enemy base/space station is destroyed or the enemy forces are destroyed. In space skirmish mode, all players have a space station that can be upgraded. In land skirmishes, all players start with bases and must research upgrades and capture reinforcement points while fighting to destroy the enemy's base or command center. Skirmishes come in two types: land and space. Skirmish mode is the familiar, classic RTS mode. The campaign is very similar to Galactic Conquest, although the Galactic Map is gradually opened for play as the player completes scripted events and completes missions. Campaign missions build up to the plot of Star Wars and eventually, the Battle of Yavin. The storyline campaign follows a semi-open linear path, where the given side must complete sequential mission objectives (such as stealing X-wing prototypes). In land battles, a player can field more units at a time if they capture Reinforcement Points. In each battle, each side may only have a certain number of units on the field at a time the rest are retained as Reinforcements, which can be called in any time to designated areas when allowed. The defender may also use any buildings (land) or their space station (space) if they have constructed them.

Factions must battle across both space and land maps. The player(s) can use only the equipment they brought to the battle (be it an X-wing squadron or an AT-AT).

When enemy forces meet (either fleets in space or ground forces landing an enemy planet) a battle ensues. Each planet confers different advantages to its owner, even though some bonuses are specific to each faction (for example, controlling Kuat reduces the price of Imperial Star Destroyers by 25 percent). Credits are used to research technology, build defenses and vehicles, and train troops. The player receives funds from planets they control and from mining facilities. Grand strategy, production, and resource management are facilitated through a three-dimensional galactic map. Each faction has at least one of three broad objectives for Galactic Conquest, which vary depending on which scenario is being played: kill the enemy leader ( Mon Mothma or Emperor Palpatine), protect or destroy the Death Star, or completely remove the other faction from the campaign map. A weaker, neutral faction of Pirates exists, but makes no attempt to battle the Rebels or Empire unless attacked.

Galactic Conquest is the sandbox campaign, in which the player controls either the Rebel Alliance or the Empire. Land battles are fought with infantry and ground vehicle units, while space battles are fought with starfighter squadrons and large spacecraft. Battles can take place on a planet (land battle) or above the planet (space battle). There are three game modes: storyline-based Campaign, Galactic Conquest and Skirmish.
