GLAZX

a small, open-source game for ZX Spectrum 48/128 in classic arcade style

About

The GLAZX is designed as local multiplayer game and the current version only supports multiplayer for two players. The game was created as an interesting challenge and dev experience for the computer on which I played my first game sometime in 1992.

How to play

The GLAZX is a very simple action game in which the reaction speed is more important than solving puzzles or strategic planning.

The glazes are placed on a grid-like map with passable cells and obstacles, and can be moved to the right one cell. The glaz emits deadly rays. The wall prevents your moving and stops rays. Randomly bonus boxes will appear on the map with energy, additional rays and other bonus abilities. Immediately after damaging the glaz can not shoot for a while and can not be damaged again. It's called "ghost time". The winner is the glaz that destroyed all opponents.

There are several modifications of the game which can be selected in the options. "NORMAL" and "PRO" slightly different lives and rays count, and other parameters. In the "NO GHOST" there are a lot of lives and there is no ghost time. In "ONE SHOT" you have only one shot, the bonus also gives only one extra shot, but the bonuses appear frequently.

The game includes 12 maps (+ 4 secret map), 4 types of bonuses, 4 game modes, 2 special attack movements. Zx 128 version contains AY chip title music and advanced sound effects.
