Prepping blueprints for expansion...
Colossus is a stub and needs your help. You can help by expanding it.
Please refer to the talk page for further discussion.
The Colossus only spawns in the Forgotten Fortress. This unit acts like a heavy armored Scrapbus. A good counter to this unit are the Zone Troopers/Black Hand or Mammoth Tank/Avatar and Predator/Scorpion. If you try to counter it with an upgraded Cobra, most probably the Cobra will die in the attempt. Not recommended.
