The Ultraverse Prime & Microcosm package appears to be a compilation, but it's actually the first and only release of Ultraverse Prime . Originally envisioned as an SNES game, it was not completed and eventually released as a Sega CD title as a pack-in with Microcosm , a separate game that was released before. This should be considered the base entry for Ultraverse Prime .
The gameplay is similar to action-adventure games like Final Fight or Streets of Rage . Players control superhero Prime, a 13-year-old boy named Kevin Green who can transform into a superhero adult version of himself. Prime can punch, kick, and jump, combining these moves with new combos. Players and enemies can also find objects to pick up and throw, with some stages featuring fast-paced action as Prime flies at high speed.
As a bonus, the game includes access to 15 different Ultraverse Prime comic book issues through the main menu, along with video interviews with writers and artists.
The game design maintains its typical SNES feel, with no changes made to take advantage of the Sega CD platform's advanced features. Despite this, the fighting style is slightly different, and a 7-minute rock theme song has been added along with the bonus features.
