The game is a roguelite FPS set in the Serious Sam universe. Teams of up to five players fight through ever-changing universes, stacking boosts and run modifiers that alter the rules of each run.

Each of the five playable characters is a Sam from a different dimension with distinct abilities. Players carry familiar series weapons alongside new armaments, and face returning enemies plus newly introduced monsters. An offline solo mode supports single-player runs. A Steam sale for the Serious Sam series is also running alongside the launch discount.
