The Mamutman could either fire a bullet at the player or whack them with their gun. It was weak, but what made it unique is that it was able to ride a Mamut. It was ejected from the Mamut after the Mamut had lost most of its health.
The Mamutman appears as a functioning enemy in Serious Sam Revolutions and the upcoming Serious Sam Origins.
- Mamutman's cackle was reused as a secret laughter heard in Tomb of Ramses III.
