>>> TRIVIA
----------
The development name of the game was 'Space Invaders Part 3'. Return of The Invaders was developed by UPL for Taito. For a small softco like UPL, working on the Space Invaders franchise was a great opportunity to gain notoriety within the videogame industry. Unfortunately, Taito neglected to mention UPL in the finished game.
