Orks

Orks are big. Orks are barbaric. Orks are brutal. Orks love battle.

With each battle they take part in, the Ork horde gains bigger guns (or what they call "more dakka"), gets hold of bigger tanks and attracts more and larger Orks. Once a big enough Warboss appears, the horde becomes a Waaagh! and rampages across the galaxy.

The Waaagh! is an unstoppable force, crushing all opposition before moving on to other worlds aboard their ramshackle starships.
