the top of the screen. If a Humanoid is being captured while a Humanoid is falling to the ground, the ship will be taken to the Humanoid that is falling to the ground. Otherwise, entering the Stargate will teleport the ship to the opposite side of the planet. If the ship is carrying at least four humanoids, entering the Stargate will "warp" the game ahead three levels. This allows more advanced players to skip the easier lower levels and also get a great number of points, extra lives, smart bombs and inviso energy. Warping is only allowed in the first 10 levels and can be avoided (if desired) by flying into the Stargate in reverse so a player can instead continue in the current level. Ports Ports of Stargate were being developed for the Atari 5200 console and the Atari 8-bit family of computers by Atari, Inc. programmer Steve Baker in 1984. The game was also ported to the Commodore 64, Apple II, and IBM PC. The Family Computer port developed by HAL (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!!. Name change The Defender II name was used in some home releases, due to legal issues (according to the bonus material for Midway Arcade Treasures, Williams wanted to "make sure they could own the trademark" on the Defender name). The name Defender II has been used on many home ports and game compilation appearances, but not in arcades. The Atari 2600 port was originally sold as Stargate, but was renamed to Defender II for a later re-release. Reception Computer and Video Games scored the Atari VCS version 89% in 1989. In 1996, GamesMaster ranked the arcade version 82nd on their "Top 100 Games of All Time." Legacy In July 2000, Midway licensed Defender II, along with other Williams Electronics games, to Shockwave for use in an online applet to demonstrate the
