How to play 

Destroy incoming parasites from the top of the screen using your artillery.

Type commands into the terminal to fire your artillery at your chosen location. E.g. to fire at grid square A9, type "a9" and press enter. You may queue commands, and the artillery will fire one after another.

Destroy green and blue power-ups to reduce artillery reload time and increase aim speed. 

Increase your score by increasing your score multiplier (visible next to your score as M=x). Hits will increase your multiplier, misses will reset it. 

About

Amidst the flickering glow of CRT screens and the persistent hum of cooling fans, "Parasite Attack 1984" plunges you into the shoes of a terminal operator during the technological renaissance of the '80s. 

Your city's silhouette against the neon skyline is under threat, as a horde of interstellar parasites descends upon Earth. 

Harnessing the era's cutting-edge technology, you must deploy strategic commands and marshal your digital resources to shield humanity from extraterrestrial domination. 

Engage in a retro-style battle of wits and reflexes, where only the most adept operator will survive the 8-bit apocalypse. Ready your fingers – for the invasion is nigh, and your terminal is the last line of defence.
