A game of Supreme Commander normally begins with the player solely possessing a single irreplaceable 'Armoured Command Unit', or ACU, the titular 'Supreme Commander'. Normally the loss of this unit results in the loss of the game. These mech suits are designed to be transported through quantum gateways across the galaxy and contain all the materials and blueprints necessary to create a 37th century army from a planet's native resources in hours. All standard units except Commanders and later-summoned Support Commanders (SACU) are entirely robotic in nature, and do not require a local pilot.
All units and structures belong to one of four technology tiers or 'Tech' levels. Upgrading structures and producing advanced engineers allows the player to produce higher quality units. The first tier is available at the start of the game and consists of small, relatively weak units and structures. The second tier expands a player's abilities greatly, especially in terms of stationary weapons and shielding, and introduces upgraded versions of tier one (t1) units. The third tier level has very powerful assault units designed to overcome the fortifications of the most entrenched player. The fourth, "experimental" technology tier includes massive constructions that take many resources and a lot of time to construct.
Supreme Commander features a varied skirmish AI. The typical Easy and Normal modes are present, but the Hard difficulty level has four possible variants. Horde AI will swarm the player with hordes of lower level units, Tech AI will upgrade its units as fast as possible and assault the player with advanced units, the Balanced AI attempts to find a balance between the two and the "Supreme AI" which decides which of the three hard strategies is best for the map. The single player campaign consists of eighteen missions, six for each faction. The player is an inexperienced Commander who plays a key role in their faction's campaign to bring the 'Infinite War' to an end. Though there are fewer campaign missions than most games, each mission can last hours due to the enemy base having formidable defenses and the player having to find a way either around or through them. When the player accomplishes objectives, the map is expanded, sometimes doubling or tripling in size, and new challenges are revealed.
