Marauder, The Big Berserker Class

Marauders are as tough as they come. Trained as mercenaries, pirates or heavy soldiers, if a Marauder is around, someone's getting wrecked somewhere. They are endurant, they are strong, and they are short on patience. So if I were you, I'd step lively around them!

In-game description of Marauder.
