SeriousSamClassic

SeriouSamClassic is a family of enhanced ports of the Serious-Engine for running on modern operating systems.
It runs on Windows, Linux, FreeBSD, OpenBSD, NetBSD, macOS and adds new features not found in the games as originally
published by Croteam.

Note:
This package only provides the engine, you need a valid copy of the (proprietary) game data to launch the game.
When you first start the game, you will be asked to place your game data along the following paths:

~/snap/serioussam/current/.local/share/Serious-Engine/serioussam

~/snap/serioussam/current/.local/share/Serious-Engine/serioussamse

You can place game data in these paths before starting the game. Then the game will start immediately.

$ serioussam

To start Serious Sam Classic The Second Encounter, you can also use the command:
