Zero Wing is a 1989 Japanese shoot 'em up arcade game developed by Toaplan. Like other shoot 'em ups of the time, it featured no real plot, except to distinguish that the player is a lone hero who will save the universe from bad guys. However, it enjoyed a degree of success in the arcade, and was thus ported to the PC Engine and Sega Megadrive in 1991.

The reason for Zero Wing's popularity beyond its release as an arcade game and video game is due to the additions made to the European Megadrive version. To expand on the game's plot, an introductory cut-scene was added to the game. This introductory scene was poorly translated to English for the European release - one section read "All your base are belong to us. You have no chance to survive make your time!". Correctly translated, it should have read something like "All your bases are now in our possession. Do what you will, you have no chance of surviving!"

In 1999, Zero Wing's Engrish intro was re-discovered by members of overclocked.org, culminating in the wildly successful "All your base are belong to us" memetic phenomenon. This also popularised the introductory and level 1 background music by Tatsuya Uemura.

The console version of Zero Wing was never released in North America, however the arcade version was distributed by Williams Electronics there.

Each of the three main weapons has three power levels. Each time the same weapon is collected, the power level increases. If a different weapon is collected, it starts back on level 1 power, unless level 3 power was already attained previously. There are also two special powerups, one in level 1-1 and one in level 4-3, which increase all weapons to a special, otherwise unattainable level 4. In the intro scenes, the ZIG's windows are green. In the game, the windows change color depending on what weapon the player has.
