This is the Centauri Spawn from GC2BXCT
History Lesson
In the Terran year 2002, a Centauri mother ship was disabled in near-Earth orbit, releasing a number of small escape vehicles each in turn containing a number of (at that time) small escape pods. The inhabitants of the primitive planet quickly located the escape ships, the small pods, and the unfortunate inhabitants. Only a few survived.
Later in 2004, Earth calendar, the Centauri returned, assisted this time by the Martian High Command in response to Terran robotic exploration of the Red Planet. It took under four day/night cycles on this brutal planet for ten additional explorers to disappear near the so called Emerald City and its rival, the City of Destiny. The primitive inhabitants were obviously increasing in their brutality, as well as the power of their technology. This could not be allowed to stand.
At that time, the Centauri High Council met and decided they would need to construct a more forceful assault, triggering the mutual defense pact recently signed with the Empire of Ork. Over six Terran solar cycles passed until the next opportunity arrived...
Assault Four
The Orkans have been ambushed yet again. This time, the bridge linking the headquarters to the main land was destroyed, cutting off a vital route that the Orkan needed to transport food and medicine. Please help the the Orkan High Commander rebuild this bridge and get over it!
Upon success of retrieval of unit, please sign and replace as found. Your next mission is to go and locate the other color nano's secretly placed around the area, and help the Orkan people regain control of their land, and be at peace again.
