Arrrgh.
The game's concept was certainly unoriginal -- you fly a little space fighter through a metallic, tubular, "futuristic" environment, shooting various bad guys in an unending succession. In 1989, that stuff was the Golden Hits of the era -- I loved Gradius, why wouldn't I love this? Well, there's always the completely nonsensical control scheme: you had to push "up" to float your little ship away from the ground, and the second you stopped doing so, it started falling back to the ground. Sure, there are weird ships and craters spewing crap at you in all directions, but apparently the most powerful force in Cybernoid is also the least science-fiction-y: gravity. So, the whole time you're trying to maneuver your ship through "fierocious" "battles," you're also just trying to keep the little trooper in the air. Great fun.
Couple this completely useless gameplay quirk with the lack of a save or password function, and you've got a thoroughly unenjoyable playing experience for whatever fraction of an hour you decide to dedicate to it. Along with its ho-hum graphics and forgettably bland music, these features have doomed Cybernoid to the status of The Most Regrettable Video Game Purchase I Have Ever Made. It is so bad that I feel any review in the positive numbers is far too generous.
