flatpak install io.github.glkarin.quake4
Quake 4 is the true sequel to Quake II, continuing the Strogg vs. Humans storyline from the point where Quake II ended.
This is a Flatpak distribution of the official Linux port of the game, for ease of use as the game can be difficult to run on modern systems.
PLEASE NOTE: This Flatpak does not include the Quake 4 game data or a CD key. You will need
to supply both. At least the files pak001.pk4
through pak012.pk4
from a retail installation of Quake 4 must be copied to
$HOME/.var/app/io.github.glkarin.quake4/q4base/
.
