What it is

Serious Sam Classic gathers the source code of the Serious Engine v1.10, the engine behind Serious Sam: The First Encounter and The Second Encounter, with a version ported to Windows, Linux and macOS. The repository includes the game logic, the dedicated server, the engine tools (modeler, world editor, entity compiler) and the third-party libraries for OGG music. The latest release is 1.10.7 (2024).
