SF-X

Pilots take to the skies in SF-X, a two-player vertical scrolling shooter from Nihon Game, released in Japan in 1983. As space fighters, players maneuver through increasingly challenging levels filled with enemy formations and obstacles. The game demands precise control as you navigate your craft using an eight-way joystick, dodging projectiles and attacking approaching threats. SF-X presents a cooperative experience where two players work together to clear each stage. Enemies vary in type and movement patterns, requiring adaptable strategies for success. While known as "Skelagon" outside of Japan, the game’s title is actually short for “Space Fighter-X.” The game's technical specifications include Zilog Z80 processors powering both gameplay and sound, along with General Instrument AY8910 chips contributing to its audio output. Players use two buttons per control stick to perform in-game actions during the intense aerial combat.
