Do you remember the old DOS game Tyrian? It's a spaceship shoot 'em up game. Man I used to love playing that game. I still have the original floppy disks and had the game setup using dosbox under Ubuntu. It worked but wasn't as good as running under native DOS.
Well, the game was recently opensourced and you can get it from www.playdeb.net for native Ubuntu Linux.
Well after the install all I can say is AWESOME! The opentyrian version is EXACTLY the same game and it includes all game episodes. This is great, I'm off to play another round.
