Cyber Core. is a 1990 vertically scrolling shooter video game developed by Alfa System and published in Japan by Information Global Service (IGS) and in North America by NEC for the TurboGrafx-16. Set in the year 2269 where Earth has been overrun by an alien race known as Hyper Insects, the player controls a Chimera bio-fighter craft, piloted by the enforcer Rad Ralph (Kato Melange in the Japanese version) in order to fend off the invaders and reclaim the planet. Similar to Dragon Spirit, Ralph has a projectile weapon for destroying air-based enemies and a bomb for destroying ground-based enemies.

Co-headed by director Kenji Hisatomi and producer Kotoshi Yokoyama, Cyber Core was the first shoot 'em up title created by Alfa System, who would later work on future projects such as Down Load and the Shikigami no Shiro series. First released on the TurboGrafx-16, the game was ported to the X68000 by SPS, featuring improved visuals and audio, as well as a rebalanced difficulty. The X68000 conversion has since been re-released only in Japan for Microsoft Windows through D4 Enterprise's Project EGG download service.

Cyber Core on the TurboGrafx-16 received mostly positive reception from critics, but the X68000 conversion was met with mixed reception; reviewers drew comparisons with Dragon Spirit due to its gameplay system but praise was given to its technical performance, visual presentation, sound, and fast-paced gameplay, but criticism was geared towards the repetitive action and enemy attack patterns, while many were divided in regards to its difficulty.

Gameplay 

Cyber Core is a science fiction-themed vertical-scrolling shoot 'em up game. The plot takes place in the year 2269, where Earth has been overrun by a cybernetic alien race called Hyper Insects. Their primary base is an underground mobile fort known only as the mothership. To fend off the Hyper Insects, Earth's defense forces create an insect-themed bio-jet in similar form to the enemy called the Chimera, which mutates the pilot into a humanoid insect upon use. This occurs to protagonist Rad Ralph (Kato Melange in the Japanese version), who has been assigned to attack the Hyper Insects and reclaim Earth.

The gameplay structure is similar to Xevious and Dragon Spirit. The player controls the Chimera through eight increasingly difficult stages over a constantly scrolling background, populated with an assortment of enemies and the scenery never stops moving until a boss is reached, which must be fought in order to progress further. The Chimera moves in eight directions and is equipped with two main weapons: a projectile weapon for air-based enemies and a bomb for ground-based enemies. The Chimera can mutate into four types of weapons by collecting their respective color eggs when shooting at the supply carrier.

Collecting three eggs in a row also grants the Chimera shield units to sustain enemy hits but this can also prove to be a risky proposition, as the Chimera's size is increased when more weapon eggs are collected. The Chimera can also acquire special egg types, which are dropped when firing at bosses or enemy formations, that grants additional abilities such as invincibility and a destruction egg capable of obliterating enemies and bullets on-screen. The Chimera is equipped with a speed setting, which can be increased or decreased across three levels by pressing its dedicated button. The title uses a checkpoint system in which the Chimera will start off at the beginning of the checkpoint the player managed to reach before dying. Getting hit by enemy fire reduces the Chimera's firepower and shield, which results in losing a live once the shields are depleted. The game is over once all lives are lost, though the player can use limited continues at the title screen to keep playing.
