Grex: Part III

Grex: Part III is the third entry in the Grex Series. It continues the adventures of Grex and Wolffe as they dismantle the Empire's plan to harness ancient Istorion power. 
Part III is considered to be the final entry in the "original" Grex series, as all entries after Part III veer from the original ideas of the series. 
== Plot ==
Grex calls upon Project CD to aid him in uncovering ancient Istorion relics within the HAHS mining colony. This draws the attention of a new enemy, The Empress. 
An Istorion security droid, Quadraxon, is activated and pursues Grex as the members of Project CD escape to the surface. Grex battles with Quadraxon, feeling some sympathy for the droid as it was only meant to defend the civilization. Grex eventually discovers another tomb, unlocking new abilities for his powersuit. 
The Purge Troopers, led by Commander Bloodbath (who wields the ancient Darksword), are now in full pursuit. of both Grex and Wolffe. While the Empire is distracted, Space Pirates intercept a transmission and learn of the HAHS. Amidst the confusion, Bloodbath personally slaughters all members of Project CD. Grex destroys Quadraxon and descends to the lower levels of the mine. 
Wolffe travels to the Imperial Station in orbit to hold off the Empire directly. The Empress senses his presence, and with Bloodbath preoccupied, pursues Wolffe personally. After an intense battle, Wolffe is able to kill The Empress, only to be impaled by Bloodbath immediately after. Grex retreats to the surface to aid Wolffe, but is too late. He battles Bloodbath as the Space Pirates enter the atmosphere. As the Pirates destroy the colony and attack the Station, Grex gains the upper hand and kills Bloodbath. He escapes moments before the HAHS Station is destroyed.
