Package details
openSUSE:

Hexen II is a class based shooter game by Raven Software from 1997.
Hammer of Thyrion is a port of the GPL'ed source code released by
Raven.
This package contains binaries that will run both the original
game and the Portal of Praevus mission pack, a dedicated server and
a launcher application which provides a GTK gui for launching
different versions of the game.
NOTE: Hexen II source, and the Hammer of Thyrion source port, are
free but the game itself is not: You must have an original copy of
the game released by Raven Software and Activision. If you don't,
then download the hexen2demo package and use the hexen2-launcher
and add the path /usr/share/games/hexen2demo to play the demo.
