Zero Wing (2P set)

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 Mega Drive by Toaplan on May 31, 1991, in Japan, and by Sega during the following year in Europe, followed by a Japan-only release by Naxat Soft on September 18, 1992, for the PC Engine's CD-ROM².

The European version of the Mega Drive port was the source for "All your base are belong to us", an Internet meme which plays off the poorly translated English in the game's introduction.

Set in 2101, the game follows the signing of a peace treaty between the United Nations and CATS, an alien cyborg. However, CATS breaks the covenant and takes control of the Japanese space colonies. The protagonist leads the ZIG spacecraft, managed to escape from the mother ship destroyed by CATS, with the aim to defeat enemy forces and liberate the Earth.

As with other scrolling shooters, the aim of the game is to shoot all enemies that appear on screen and avoid getting obliterated by enemy fire, crashing into enemies or into foreground scenery. There are mid-level and end-of-level boss enemies that stay with the player until they are defeated. The game features eight levels.
