Disk Version Manuals Cover


The original Isotopia game on +3 disk format with a complete level editor that will allow you to create your own challenges.

The editor allows the creation of levels designed by the user. We can freely create them from the beginning or modify the original levels of Isotopia without any limitation. The edited levels may be subsequently inserted and used in the original program.

In addition, throughout the editing process, we can test the levels before inserting them into the game to check their playability.

Unleash your madness and face an inexhaustible challenge.
