Serious Sam: Siberian Mayhem is a new stand-alone expansion to the world of the classic FPS series. Join the fight against Notorious Mental on a journey through the wild lands of Russia, and find your way through this lost chapter of Sam Stone's adventures.
The game delivers the classic Serious Sam experience - players must utilize a wide array of powerful weapons and gadgets to mow down massive waves of diverse alien creatures, from the returning Kleer Skeletons and Harpies to new enemy types like the agile Marsh Hoppers and heavily-armored Octanian Grenadiers. The gunplay is fast-paced and satisfying, with each weapon feeling distinct and impactful. Players must constantly dodge and weave through the relentless onslaught of enemies.
The levels feature more varied and well-crafted environments than the previous game, with combat arenas thoughtfully designed to encourage dynamic movement and positioning. Elements like jump pads, turrets, and destructible cover add layers of strategy to the encounters. The encounters are also more skillfully structured, striking a better balance between overwhelming enemy numbers and giving the player enough space to maneuver.
The game introduces a number of new weapons and gadgets that expand the player's arsenal. Standouts include the powerful AK-47 assault rifle, the versatile Perun Crossbow, and the devastating Laser Cannon, which complement the classic arsenal of Shotguns and Rocket Launchers. Gadgets like the Hoverboard and Rage Serum provide additional movement and combat options, adding more tactical flexibility.
The levels contain a wealth of secrets to uncover, ranging from throwback levels harkening back to classic Serious Sam to hidden power-ups and collectibles. Searching for these secrets provides a tangible sense of discovery and incentivizes revisiting levels.
The difficulty ramps up gradually, with early levels providing a warm-up before throwing the player into increasingly intense combat scenarios. Even on the highest difficulty setting, the game feels fair, with players able to overcome the challenges through skillful play rather than through pure attrition.
