Stargate (1981) is the sequel to Defender, adding an invisibility cloak and a warp gate to Williams' demanding side-scrolling shooter.
Stargate keeps everything that made Defender hard — the wraparound planet, the scanner, the humanoids to protect, the dense controls — and adds more. The inviso button cloaks the ship and destroys anything it touches, and the Stargate warps the player across the planet, straight to a humanoid in trouble. Eugene Jarvis and Larry DeMar designed it as a refinement of their earlier game, and it is often regarded as the purer challenge of the two.
Stargate was designed by Eugene Jarvis and Larry DeMar at Williams Electronics in 1981 as the sequel to Defender. Jarvis added the inviso (temporary invisibility), the phaser (fires across the entire screen), and the eponymous Stargate — a warp tunnel allowing instant travel across the playfield. The game is considered by many to be a refinement of Defender rather than a true sequel, as it retained all the original mechanics while adding complexity.
