Return of the Invaders

The player must use a 2-way joystick to direct a cannon (this time, referred to as "Xerovy") across the bottom of the screen while using a single button to fire shots up at formations of descending invaders (this time, the regular invaders are referred to as "Flector", and the new "deflector" and "master" ones are referred to as "Legard" and "Zicon" respectively); the shields (or "barricades") are also referred to as "Xero-Guards", and the lights in them will change colour fr
