Sol-Feace was one of the earliest Mega-CD games to be released, debuting in Japan in December 1991 as one of two launch titles for the system (the other being Heavy Nova). It was also a launch title for the Mega-CD in Europe, sharing a box with Cobra Command and being bundled with launch units in the United Kingdom and Italy. It would also be bundled with launch North American Sega CD units, and as it was never given a stand-alone release, effectively went out of production when the redesigned Sega CD units went on sale.
In the year 3300, a supercomputer called GCS-WT is built to unite society (spread out over 300 solar systems) through diplomacy, but decides to spiral society into a dystopia it rules as a dictator. Only the scientist Edwin Feace was able to escape GCS-WT's reign — by leaving the solar system and settling a newly discovered planet, where he builds the Sol-Feace, a ship which, when mass produced, should form a sizable enough army to defeat GCS-WT. Unfortunately, GCS-WT finds out and kills Feace and the natives of the new planet who aid him, leaving only two soldiers and one Sol-Feace to stop GCS-WT.
Sol-Feace is a generic shoot-'em-up: , , and all shoot and can be held down for rapidfire. Powerups can be found by shooting capsules. Touching extra weapons with the upside or downside of the ship determines where they are be mounted. The angle of said extra weapons can be altered by moving forward or backward.
