Zero Wing is a horizontal shooter game where the player controls a ZIG, an escape pod released after its main ship was attacked and destroyed by the evil cyborg CATS, bent on taking over the world.
The gameplay involves collecting upgrades to access more powerful versions of three color-coded weapons: red (scatter), green (homing) and blue (lasers). The player can also use a traction beam to trap an enemy and then throw them against their peers, destroying them.
Released in 1991 for the Sega Genesis, Zero Wing has become infamous for its quirky English translation, which introduced the phrase "All your base are belong to us" – a grammatically incorrect expression that has since become an internet meme.
