Space Invaders II is a western-only sequel to Space Invaders released by Midway in 1980 for Arcades. It is the first version of Space Invaders to add a two-player competitive mode.

When playing with two players, the second players controls a Core Cannon on the top of the screen while the invaders remain on the middle. The objective in this mode is to destroy the opposing player while fending off the invaders.
