Starsiege

Prometheus, father of all Cybrids, instigator of the first two Earthsiege games, is still out there somewhere. The Dark Intellect has learned, and it is hiding in the outer edges of the Solar System, learning, observing, and waiting for the perfect moment to strike. Meanwhile, the Human Empire is tearing itself apart. The decree by Emperor Petresun, the original creator of Prometheus, to defend Earth first, while practical, does not sit well with the colonists of other planets, who remember how helpless they were during the previous Earthsieges, and how Earth never sent any help until it was too late. When the brutal crackdown began, the Martian Resistance has formed. Prometheus found his chance to strike when the Emperor ordered his Imperial Knights to attack the Martian Resistance, and the Starsiege has begun...

Starsiege is a battlemech vehicle simulation. The battlemechs in the game (called HERCs) have shields, meaning that the player needs to coordinate the weapons to bring down the shields, then punch through the armor. The weapon mounts are different sizes, making it possible to fit different types/sizes of weapons to them. The other mounts for equipment (engine/shields/powerplant) also have different sizes, limiting/challenging the player's outfitting decisions. Other equipments include shield amplifier, cloaking device, ECM, and more. There are multiple sizes of HERCs available, as well as some ground vehicles (which cannot be shielded). The player is also able to load the camo scheme into a paint program and edit it. It is possible to play the campaign on either the human or the Cybrid side, as well as join other players online in large-scale multiplayer battles.

The European release of this game features the complete game Starsiege: Tribes as a free extra.
