       opentyrian - an open-source port of the DOS game Tyrian

       opentyrian [OPTIONS]

       Tyrian is an arcade-style vertical scrolling shooter.  The story is set
       in 20,031 where you play as Trent Hawkins, a skilled fighter-pilot
       employed to fight MicroSol and save the galaxy.

       Tyrian features a story mode, one- and two-player arcade modes, and
       networked multiplayer.

       A summary of options is included below.

       -h, --help
              Display help and exit.

       -s, --no-sound
              Disable audio.

       -j, --no-joystick
              Disable joystick/gamepad input.

       -t, --data directory
              Set alternative Tyrian data directory.

       -n, --net host[:port]
              Start a networked game; host is the IP address of your opponent.
              Use this option together with --net-player-name and
              --net-player-number to join game.

              OpenTyrian uses UDP port 1333 for multiplayer, but in most cases
              players will not need to open any ports because OpenTyrian makes
              use of UDP hole punching.

       --net-player-name name
              Set name as your alias for multiplayer game.

       --net-player-number number
              Select ship; number is either 1 or 2 depending on which ship you
              intend to pilot.

       -p, --net-port port
              Set local port to bind.

       -d, --net-delay frames
              Set lag-compression delay.

       -x, --no-xmas
              Disable Christmas mode.
