Zero Wing (ゼロウィング?) is a 1989 side-scrolling shoot 'em up arcade game developed by Toaplan and published by Taito. The player is a lone hero who will save the universe from an evil force.
It enjoyed a degree of success in arcades and was subsequently ported to the Sega Mega Drive by Toaplan on May 31, 1991 in Japan, and by Sega during the following year in Europe, followed by a PC Engine CD-ROM release by Naxat Soft on September 18, 1992 only in Japan.
The European version of the Sega Mega Drive port was the source for "All your base are belong to us", an Internet meme which plays off of the poorly translated English in the game's introduction.
