Developed and published by Psygnosis and released for the Sega CD in 1993/1994, Microcosm is an ambitious sci-fi rail shooter designed to showcase the possibilities of CD-ROM technology. Its cinematic presentation and unusual journey through the human body are impressive for the hardware, but shallow gameplay and brutal difficulty make it far more interesting as a technical showcase than as a game. Rating: 5.5/10.
Set in the year 2051, Microcosm takes place in a dystopian future dominated by enormous corporations. Cybertech president Tiron Korsby has been infected by rival corporation Axiom with a microscopic device designed to seize control of his mind. The solution is appropriately extreme: send a miniaturized agent inside his body to hunt down the invading machines before they reach their objective.
It is a wonderfully strange premise, essentially combining Fantastic Voyage with early-'90s cyberpunk. The lengthy opening sequence immediately demonstrates where Psygnosis placed much of its attention. Digitized actors, computer-generated imagery, dramatic music, and elaborate cinematics give Microcosm a scale rarely seen in conventional cartridge games of the period.
Once the actual game begins, however, things become considerably simpler. Your craft moves automatically through pre-rendered tunnels while you control its position on the screen, dodge hazards, and fire at biological creatures and Axiom machines. Different stages take you through areas including the lungs, arteries, heart, and eventually the brain, with several vehicles used during the journey.
Power-ups provide upgraded fire modes, lasers, shields, smart bombs, and other useful weapons. There are also bosses and occasional changes in scenery, but the fundamental gameplay rarely evolves beyond moving and shooting.
Initially, it can be exciting. The constantly moving FMV backgrounds create a convincing illusion of travelling at high speed through a three-dimensional environment, and some of the organic scenery remains striking considering the Sega CD's limitations. Unfortunately, the restricted color palette leaves much of the video grainy and heavily dithered, while enemies and projectiles sometimes disappear into the busy backgrounds.
This contributes directly to Microcosm's biggest problem: its difficulty. Judging depth can be extremely difficult, your craft occupies a substantial portion of the screen, and incoming attacks are not always easy to read. Damage can feel unavoidable until you memorize what is coming, turning later sections into exercises in trial and error rather than pure reaction.
Long stages make failure even more frustrating. Passwords allow you to continue your progress, but the repetitive structure means replaying sections can quickly become tedious. There simply isn't enough variety or mechanical depth to sustain the game's length.
The audio fares much better. Atmospheric electronic music complements the surreal environments perfectly and helps maintain the dark cyberpunk mood even when the action becomes monotonous. Combined with the impressive intro and pre-rendered visuals, it gives Microcosm a distinctive identity that many technically better shooters lack.
Microcosm ultimately represents both the appeal and the weakness of the early CD-ROM era. Psygnosis created something that looked futuristic and cinematic in screenshots and demonstrations, but the interactive element never received the same level of sophistication. It is worth experiencing for its atmosphere, unusual concept, music, and technological ambition, but beneath the impressive exterior lies a repetitive and often frustrating rail shooter.
