Maelstrom is a game similar to Asteroids.

You pilot your ship through the dreaded "Maelstrom" asteroid belt --
suddenly your best friend thrusts towards you and fires, directly at your
cockpit. You raise your shields just in time, and the battle is joined.
The deadliest stretch of space known to mankind has just gotten
deadlier.

This package also comes with a script to create Slackware packages
from the Maelstrom add-on graphics/sound files.
Run 'maelstrom_addon_package.pl --help' for more information.

Note to users of 64-bit and other non-x86 Slackware derivatives: you
won't be able to host or join multiplayer games that use a server.
Peer to peer (without the -server argument) multiplayer works OK though.
