GraphicsLike all Game Arts games republished by Sierra, Thexder uses 640x200 graphics in EGA to its advantage by simulating 64 colors via dithering.
MusicThe title theme for the game was Beethoven's Moonlight Sonata.
ProgrammingBecause this game used a tile-based playfield, it ran very smoothly, even on low-powered machines. Only the tiles that changed needed to be redrawn, resulting in scrolling that was quick, even for a 4.77MHz machine.
Tandy 1000Thexder was one of the few games that really excelled on a Tandy 1000. The game ran at 320x200 16 colors. (the Tandy wasn't quite as flexible as an EGA) and in this video mode it seemed to look cleaner and more vibrant. Also the music sounded great on the TI sound chip in the Tandy.
