Neoclyps is a kind of Scramble'd Defender or, if that doesn't make sense to you, a version of the Atari 400/800 game Protector. If that doesn't make sense either, then I'll explain.
You, says the blurb, are the "good guy", whose planet Neoclyps has been invaded by the "bad guys". Naturally, you want to pulverize these villainous invaders and get your planet back: but that's not so easy.
As in Scramble, you have a ship which you pilot over an uneven landscape. Your opponents are located in various radar towers close to the ground and also whirl about in the air in the form of missiles. To destroy the towers it is necessary to first destroy a missile; this then gives you a shield which enables you to fly through buildings. So you swoop down, blast the towers and get out quick. Since the shield only lasts four seconds even at the lowest level - this is easier said than done.
Neoclyps has four combat zones, each with different opponents. The graphics and landscape are remarkably good, with arcade-quality definition.
Although Neoclyps is a fine shoot-'em-up, it would be improved if the player had a scanner to survey the enemy, and if the game occupied rather more of the screen than it does.
