RayForce

is a vertical space shooter style game by Taito released for the Taito F3 arcade hardware in 1994 and later ported to the SEGA Saturn in 1995.

Due to trademark problems, when the home version was released in Japan it was renamed Layer Section. Finally, when Acclaim got a hold of it for the North American and European home releases, it was renamed yet again as Galactic Attack. To add more confusion, the game was also titled Gunlock in European arcades.

Story
In the distant future, human governments, across the planet Earth, construct a massive supercomputer, named "Con-Human". The purpose of this computer is to govern the planet's environmental systems, verifying proper nutrients and care is provided to ensure the culture of humans and animal alike.

However, disaster strikes when, after a cloned human's mind is linked with the system, Con-Human becomes sentient and insane. It begins to induce calamities across the planet, constructing corrupt clones of existing organisms, destroying its human masters and exterminating the nature it was intended to protect, apparently intending to replace everything with what Con-Human considers improved versions of themselves.

After prolonged war, Con-Human has succeeded in exterminating 99.8% of humankind, with the remnants fleeing to space colonies. Meanwhile, Con-Human remakes the very interior of Earth. As a result, Earth, as humanity knew it, has utterly ceased to exist, transformed into a planet-sized mobile fortress that is in fact Con-Human's body. Con-Human intends to use the transformed Earth to seek out and destroy the colonies, erasing all remaining traces of old life from the universe and leaving only the new life that it personally created. Now, taking the full-scale offensive, mankind develops powerful ships, one of them the RVA-818 X-LAY starfighter, to fight the oppressive machine by destroying the now-infected Earth entirely.

Game system
The player is provided with a ship called the RVA-818 X-LAY, which is outfitted with two weapons: a primary weapon that fires straight lasers and increases in power when the player accumulates power-ups, and a secondary lock-on missile launcher, which can also be increased in power, that can target up to eight enemies at once by moving the targeting reticle. This weapon is used to attack enemies that appear on a lower plane than that of your craft, which are inaccessible to the player's primary weapon. During play, the screen predominantly scrolls vertically, but there is some horizontal leeway as is common in games of this genre.

Compilations
This game was also released on Taito Memories in Japan, as well as Xbox and PC versions of Taito Legends 2.

Sequels
At a point Taito worked on a sequel, R-Gear; however, that was canceled early in development, in favor of RayStorm.

A prequel, RayCrisis, was released in 1998.

Influence
A few games have been made that copy the general feel of RayForce, most notably Kamui and Terra Diver. Both games feature an auto-lock weapon that can fire at a lower plane, as well as an epic descent to an earth-like planet for assault missions.
