The Seiddab Trilogy is a series of video games designed by Steve Turner (as Graftgold) for the ZX Spectrum and published by Hewson Consultants.

Your Spectrum's review highlighted the realistic 3D effect and split-screen display, but criticized the monochrome graphics and slow game speed.

[7] Sinclair User awarded 5 out of 10, criticizing the unclear, flickering display but praising a sophisticated concept and satisfying explosions.

[8] Personal Computer Games were unimpressed with the 3D effect and felt that the enemy ships were indistinct and the action unexciting.

[10] Below the main display are indicators for fuel, armament type in use and hull temperature, which increases to a critical point with each enemy strike.

[10] Sinclair User said that "the controls are difficult to handle and of the type where you lose position rapidly through having to over-correct continually",[11] while CRASH decided that "the display is wonderful, the best three dimensional Battlezone-type game yet... Really excellent, most playable and addictive too".

[12] The game combines shoot 'em up sections with arcade adventure elements that Turner had developed with Avalon (1984) and Dragontorc (1985).
