About Serious Sam: Siberian Mayhem
Serious Sam: Siberian Mayhem is a standalone chapter in the adventures of Serious Sam Stone. Sam travels across Russia to catch up with the traitorous General Brand, who stays one step ahead, while fighting Mental's Horde.
Across Siberia
The game takes place across five levels in Siberia, from Arctic coastlines and desolate forests to abandoned villages and a ghost town. You can explore these vast, unpredictable landscapes and uncover forgotten stories and unexplored places.
Enemies and weapons
New foes and bosses join Mental's Horde, including advanced and intimidating creatures. Sam's arsenal includes new weapons such as the AK and the experimental Perun crossbow, along with new gadgets and vehicles. You can also cause destruction from above or take control of 50 tons of firepower.
Characters and secrets
New outcasts and unexpected characters help Sam on his journey to Tunguska. Side-missions reveal chronicles of the wild places you visit, and the world itself can offer clues. Siberia also holds useful, silly, weird and familiar secrets to find.
