''Star Force'' (released in North America as Mega Force), is a vertically scrolling ShootEmUp game developed by Creator/{{Tecmo}} when it was still known as ''Tehkan''. It was released in 1984.

The player pilots a starship called "Final Star" and must destroy enemy ships and structures to progress through the levels.

!!Tropes associated with Star Force:

* AlphabeticalThemeNaming: The levels are named after [[GratuitousGreek greek letters]].
* BulletHell: Sometimes, the high number of enemies turns the game into this, especially in later levels.
* CoresAndTurretsBoss: The boss of each level is a square with letter that glows. Two turrets at the side also take a potshot at the player.
* EndlessGame: In some versions of the game, there is an additional level called "Infinity", which occurs after Omega (the final level), after which the game repeats indefinitely. In the NES version, after the game's completion, the infinity target becomes available, and the game repeats the same level and boss without increasing the difficulty.
* GratuitousGreek: The names of the levels.
* HardLevelsEasyBosses: Some levels may be almost impossible but at the end the player just needs to shoot up a target that does not attack the player's ship.
* NoPlotNoProblem: It's never elaborated why the player must destroy the enemies' ships.
* PaletteSwap: All levels are similar in design, but with different colors.
* ShootEmUp
* TimedMission: The ''Arcade Archives'' release by Creator/HamsterCorporation includes a "Caravan Mode", where you play through the game on a five-minute timer trying to [[ScoringPoints score as many points as possible]]. This mode is made in {{homage}} to the game's inclusion (specifically the [[UsefulNotes/NintendoEntertainmentSystem Famicom]] port) in the very first "Creator/{{Hudson|Soft}} All-Japan Caravan Festival", and is in fact a standard feature in every game in the ''Arcade Archives'' line.
