SeriousSamClassic

About
Serious Sam: The First Encounter and The Second Encounter are 2001-2002 first-person shooters by Croteam in which Sam "Serious" Stone battles large waves of enemies with an expanding arsenal across ancient Egypt and beyond. SeriousSamClassic is a cross-platform build of the open-source Serious Engine, running on Linux, FreeBSD, OpenBSD, NetBSD, Windows, Raspberry Pi, and macOS, and packaged for several Linux distributions and package managers (Arch AUR, Gentoo, a PPA) as well as Flatpak, Snap, and AppImage.
How it differs from the original
Requires the player's own copy of the original Serious Sam Classic .gro data files, and optionally supports the fan-made XPLUS high-definition asset mod; unlike the related SeriousSamClassic-VK repository, this build uses the engine's classic renderer rather than Vulkan.
Getting started
Install via your distribution's package manager (AUR, a Gentoo ebuild, a PPA, Flatpak, Snap, or AppImage) or build from source with CMake and make, then copy the original Serious Sam Classic game's .gro files into the SamTFE/SamTSE folders before launching.
