rott (Rise of the Triad, first person shooter game)

Rise of the Triad is a high quality, fast scrolling first-person
perspective 3D action game. It includes a lot of destructive enemies,
an arsenal of weapons from simple pistols to missile launchers,
life-preserving armor, traps and ambushes galore.

WARNING: Rise of the Triad features wanton and gratuitous violence.

In order to play the game, you need the data files from either the retail
or shareware (demo) version of the game. See README_gamedata.txt for
details. If you want to include the shareware game data in your Slackware
package, download the file http://icculus.org/rott/share/1rott13.zip
and place it in the directory with the SlackBuild script, before running
the script.

Multiplayer games (aka comm-bat) are NOT truly supported: you can start up
a comm-bat game, but you can only play by yourself (no actual networking
code exists in this version of the game).
