How To Launch The OCEAN Demo Under Linux

Wanted to write this manual anyway, so here goes! Please note this applies mostly to Debian/Ubuntu, so for other distributions, please consider using their respective utilities (packet managers, installation from source, etc.)

• Download and install libsdl-dev:
  sudo apt-get install libsdl-dev
• Download and install GZDOOM:
  sudo apt-get install gzdoom
• Also, you can download the pre-compiled DEB package here: http://debian.drdteam.org/pool/multiverse/g/gzdoom/
• Download and unpack the OCEAN Demo
• Place the files ocean24.pk3, doom2.wad and system.wad (or, generally, all the WAD and PK3 files except brightmaps.pk3 and gzdoom.pk3)...
• ...to the GZDOOM folder: /usr/games/gzdoom
• Open the terminal and type: gzdoom -file doom2.wad -file ocean24.pk3 -file system.wad
• Be aggressive!
