Prometheus is believed destroyed, but the Cybrid menace has not ended. As the humans expanded out into interstellar space, we've found more Cybrids, and they will be exterminated wherever they are found...

As a new commander at Unitech, your job is to command your bioderms (cloned pilots) and the Hercs to mine the various planets in the system, wipe out any Cybrids you see, and eventually take out the main Cybrid nexus in the system. As you advance in rank you will gain access to more power tech, HERCs, and more valuable bioderms. Each planet has different terrain that'll affect how you fight, and your bioderms will grow in experience and even perish in combat. Make money by mining and killing Cybrids to afford the weapons, HERCs, and bioderms. With hundreds of different weapons (projectile, laser, plasma, missile, indirect, ELF, special) and plenty of other equipment to mount, and over a dozen different HERC models to outfit, variety is endless. With three systems to exterminate, there will be plenty of battles to perfect your skills.

The game itself is played like Earthsige, except in 2D overhead-semi-isometric view, turn-based hex movement. While the action can be a bit slow, the graphics are good, commands are intuitive, and coordinating fire among all the different HERCs to maximize destruction is not a simple task. You can even administer some chemicals to the bioderms to maximize their effectiveness temporarily (at a cost of some genetic instability, which could be fatal if prolonged).

It was possible to go online at play against others on Sierra's WON.NET, but not certain if they still offer that service now. You can choose to fight other corporations (with or without Cybrid presence) or play other standard games. The HERCS have value ratings so it's easy to balance the forces.

In the original release, mission 7, which require you to destroy the main Cybrid base in the system, is so hard that it's nearly impossible as you can't command that many units at your low rank. The developers had to release a patch which smoothed out the difficulty. Mission 7 enemies were reduced, but "level 5" enemies armed with elite weapons were added to the final levels. The original game had only four levels of enemies.


The box contains two identical CDs. The additional CD is meant to serve for multiplayer purposes, so your friend didn't need to buy another copy of the game. This was the first game to do this,


There are two video-tutorials (in AVI-format) on the CD, explaining the basic game concepts.
