Collosatron

Unleash apocalyptic mayhem in Colossatron! In this action game, you’re a giant snake-like robot attacking the earth. Colossatron has crash landed on earth and is attacking our military bases. Merge colored weapons and create the most fearsome alien robot of all time to wreak maximum destruction! 

How to play Colossatron?

Colossatron will automatically attack and destroy everything around it. The military will fight back with increasingly powerful tanks, planes, and other weapons.

Colossatron’s body is made up of different weapons. To keep Colossatron alive, grab the weapon modules that appear on screen and drag them to Colossatron’s body. They will become part of Colossatron and make this monstrous alien more powerful.

Try to combine different colors to create different weapons. Three weapons of the same type will also merge together to form an even bigger and more powerful weapon.

When weapons get too heavily damaged by the military barrage, they will be ejected from Colossatron’s body. When Colossatron has no more weapons (and no more body) left, the round is over.

Use the energy modules you collect at the end of each round to upgrade Colossatron’s weapons for the next round of attack!
