The Mothership can also build Carriers, which themselves can build any ship from the Fighter, Corvette and Frigate families.

The Mothership is capable of constructing all but the very largest ships, which must be built using Shipyards (the game states these are built at orbital facilities and arrive via hyperspace). The player's fleet is centered on the Mothership, the destruction of which results in an immediate Game Over in a single-player game, and is a critical loss in a multiplayer game. RUs are the currency for both ship creation and technology research, placing limits on what combination of shipbuilding and new technology research can be carried out in a single game. Gameplay in Homeworld 2 depends on so-called 'Resource Units,' (RUs) which are collected by harvester craft. Units are moved three-dimensionally using a combination of mouse movements and key presses to modify the z-axis of the destination position.

Homeworld 2 shares the movement system and three-dimensional play area of its predecessor.
