Star Gate

Stargate (named Defender II on NES) is an arcade game released in 1981 by Williams Electronics. Created by Eugene Jarvis and Larry DeMar, it is a sequel to the 1980 game Defender, and was the first of only three productions from Vid Kidz, an independent development house formed by Jarvis and DeMar.

The Family Computer port developed and published by HAL in 1988 (renamed Star Gate, later named Defender II for US release) seems to be related to their Millipede (renamed Milli-Pede, later named back to Millipede for US release) and Joust ports, as well as Mike Tyson's Punch-Out!!, all of which were released around the same time. In particular; the title jingle for Milli-Pede/Star Gate/Joust are almost identical, the music played when Star Gate begins is a longer version of the opponent entrance music within Punch-Out!!, and the music played during Star Gate's intermission screen between waves is the same as the screen after a loss in Punch-Out!!.

Compared to the original Star Gate, Defender II uses different colors for almost every thing that can be seen in the game.

This game is endless. After playing well over 10 waves, I lose on purpose.
