Hades Nebula
Hades Nebula is a 1987 vertically scrolling shooter for the Commodore 64, ZX Spectrum and Atari ST by Paranoid Software and published by Nexus Productions. The player controls an upgradable fighter that must battle its way through thousands of enemy ships before it confronts the final boss, Emperor Hades. There are fifteen levels.
Gameplay
Enemies are face-like ships or bug-like ships that materialise at certain points in the game. Upon appearance they immediately seek out the player's ship and collide with it unless evasive action is taken. Also, every one or two levels or so, 'mother ship' bosses are encountered that take a considerable amount of bullet dodging and incisive shots to destroy.There are two sound options while playing the game: either sound effects or the musical soundtrack by Ben Daglish. The latter is the default mode, and changes depending on whether you are fighting a boss or charging through a level.
