Operation: Inner Space

Operation: Inner Space is a PC game released in 1994 by Software Dynamics for Windows computers. The shareware version is a 14-day trial with most features enabled. After 14 days, many of these features are disabled (for example, saving or loading games), and the player can only use one ship. Registration not only prevents this, but enables a new feature the Ship Factory, which allows the player to make and customize ships. A near-full shareware edition was distributed as part of the cover CD in Issue 8 of Computer Life magazine (December 1995).

Game storyline
The Inner Demon and its viruses have invaded the player's computer and infected its icons. Then the Inner Demon set up a lair in a black hole which changes position. Guarding this lair are 4 dragons each holding one of the Inner Demon's powers. Using a little spaceship, the player goes into the computer's "Inner Space" to collect the uninfected icons and stop the Inner Demon, while simultaneously improving his ship and maintaining relationships with the population of Inner Space.

Teams
There are 8 teams: the Avengers, Pirates, Predators, Enforcers, Renegades, Fuzzy Ones, Knights, and the Speed Demons.

You can play as any ship from any team, except the Enforcers who only police the many levels as bots.
