Rebelstar: Tactical Command is a turn-based tactics video game developed by Codo Technologies and published by Namco and Atari Europe for the Game Boy Advance in 2005. It's the fourth game in the Rebelstar series. The game was created by Julian Gollop, who previously designed X-COM: UFO Defense, Laser Squad and the original Rebelstar games.

Unlike in the X-COM: UFO Defense, there is no base building, resource management or research. During combat, the player controls a squad of single-character units and must accomplish various goals. Units have a certain number of action points, which are renewed at the beginning of every turn. Each action, from turning to walking to shooting consumes action points. Therefore, they are only allowed to perform a certain number of actions per turn.

The player may also pick up and use weapons from dead enemies and allies. As ammunition is limited, it is sometimes necessary to loot a corpse in order to keep fighting. As units specialize in different areas, it is important to adopt a strategy that will fully utilize the strength of each of the many weapons used. It is also possible for a character to act as a medic, using a medikit to heal comrades.

Every time a unit damages an enemy, heals an ally, or uses psionics, it gains experience points. Once they have enough, they gain a level which raises their attributes such as strength, constitution, and intelligence at random. They also gain one skill point which the player can assign to a skill of their choosing, such as heavy weapons, hand-to-hand combat, medicine or stealth. Thus, as the game progresses, each unit becomes stronger and they may specialize in a type of weapon or skill above all others.
