Tac/Scan (夕ック/スキャン) is a space combat shooter released as an arcade video game in 1982. It was developed by Sega Electronics (formerly Gremlin Industries) and published by Sega. An Atari 2600 version was released in 1983.
The game uses 3D vector graphics that switch between overhead and third-person perspectives. The player commands seven units in squadron formation through waves of attacking enemies; the player can gain reserve units, while being able to command the units to perform various actions, including firing at enemies, getting into formation, or a "tac" maneuver.
