And one more thing, they have these things called Titans, which they made during the Age of Strife, right after the AI rebellion and after Mars was made uninhabitable and was red once again.
The tallest Titan, the Imperator-class, is about as tall as the Statue of Liberty, base and all. Titans also have weaponry that can mow down cities in just a few minutes, like plasma cannons with the power of small stars to “mini” guns that form craters when they shoot, to melee weapons like chainsaws and claws.
