aka: Thexder 88

Description official descriptions

A platform shooter from Japan, Thexder offers many levels and diverse enemies that gradually increase in difficulty. You pilot a Battletech-style robot capable of switching from a mech into a jet at any time. Your weapon auto-aims, but uses up a fixed amount of rechargeable energy; if you run out of this energy, you'll have to wait a few seconds before you can fire again. Your mech also contains a shield that can be activated to protect you from harm, but this lasts for a few seconds and uses up some of your life energy.

Like all Game Arts games republished by Sierra, Thexder uses 640x200 graphics in EGA to its advantage by simulating 64 colors via dithering.


The title theme for the game was Beethoven's Moonlight Sonata.


Because 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 1000

Thexder 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.
