MissionForce: CyberStorm

Prometheus is believed destroyed, but the Cybrid menace has not ended. As the humans expanded out into interstellar space, they encountered more Cybrids, and they will exterminate them wherever they are found...

As a new commander at Unitech, the player's job is to command cloned pilots called "bioderms" and their HERCs to mine the various planets in the system, wipe out any Cybrids they see, and eventually take out the main Cybrid nexus in the system. As the player advances in rank, they will gain access to more power tech, HERCs, and more valuable bioderms. Each planet has different terrain that'll affect the battles, and the bioderms will grow in experience and even perish in combat. Money earned by mining and killing Cybrids allows to buy new weapons, HERCs, and bioderms. With hundreds of different weapons (projectile, laser, plasma, missile, indirect, ELF, special, etc.), plenty of other equipment to mount, and over a dozen different HERC models to outfit, combinations are endless. The player will be able to hone their skills in many battles across three systems.

The game itself is played like Earthsiege, but with a 2D overhead-semi-isometric view and 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. It's even possible to 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 and play against others on Sierra's WON.NET, when the service was still officially supported. Players could 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.
