In blackened heavens they hide!
—A Colossus clearing the skies from enemy aircraft

The Colossus is the monster tank and heavy anti-air vehicle of Epsilon Headquarters.

Official description

The Colossus is certainly one of the larger Epsilon ground units, towering over most tanks. Surprisingly mobile and well-armored, it can easily take on multiple foes with its psionic blaster cannons. Thanks to a streak of ingenuity of Headquarters' scientists, the Colossus not only functions effectively as a heavy assault vehicle, but as an excellent mobile anti-air defense as well.

After switching into its uniquely-designed dual anti-air gun, it can rapidly take the enemy aircraft down. Slower or stationary aircraft are especially susceptible to the rounds, rapidly fired by the Colossus at high velocity, taking even more damage the closer they are to the vehicle. This makes this behemoth of a tank a versatile weapon for the Epsilon Headquarters to take the Allied and Soviets head-on.[1]


The Colossus is arguably one of the best monster tanks available when it comes to dealing with heavily armored vehicles or buildings. Coupled with the fact that it can attack aircraft once it is ordered to deploy, the Colossus is a force to be reckoned with.

Their Psychic Blasters also deal area-of-effect damage, making them very suited to dealing with massed tank rushes. The Heavy AA Guns these tanks carry are superior to Gatling Cannons in every aspect when it comes to dealing with air threats (minus the additional damage bonus the longer it is engaged in combat), meaning they can effectively supplement them in order to relieve some demands from the HQ proselyte's power grid.

But not all is so bright with the Colossus, as its weapons are below average when it comes to dealing with infantry, and as such groups of anti tank infantry (Tesla Troopers, Desolators, etc.) are a threat to the Colossus if it's not guarded with the appropriate anti-personnel units. It is also helpless against ground attacks when it is utilizing its AA weapons, so HQ proselytes must be required to micromanage them in order to effectively use these behemoths to their full potential.

AI behavior

The AI has the ability to create Colossi in its anti-air mode without needing to switch modes first. However, the AI is not programmed to switch between Colossus modes.

Colossi controlled by the AI have the following attack patterns:

All difficulties

  • 1x entering Tank Bunker (both modes)
    • This task force may be accompanied by 1 additional Colossus of the same mode
  • 2x guarding Inferno Towers or Gatling Cannons (anti-air mode)
  • 4x targeting anything
    • The AI may use Rage on this strike force (Hard AI only)
    • If available, Invulnerability, Irradiation Beta/Gamma and Shadow Ring may also be applied (Hard AI only)


  • 1x guarding Inferno Towers or Gatling Cannons; accompanied by 1 Shadow Tank
  • 2x targeting vehicles, accompanied by 2 Opus Tanks and 2 Shadow Tanks
  • 2x following friendlies (anti-air mode)
  • 4x targeting vehicles
  • 4x targeting base threats (anti-air mode)


  • 2x guarding Chimera Core or deployed Hazequad (anti-air mode)


The first of our Colossi are ready. Use them for both anti-ground and anti-air combat.
