Cosmo’s Cosmic Adventure is a 1992 side-scrolling platformer video game by Apogee Software. The game centers on an alien child named “Cosmo” who becomes separated from his parents on an uncharted planet and goes searching for them. The game was originally released for MS-DOS but has since been made available for modern computers through Steam and GOG.com.
This was developed by the Duke I and II team, published in between the two games, and includes a Duke Easter Egg too!
With a “HD” remaster being announced (seems very similar to the Monster Bash HD remake) it may be the time to revist this old classic
