In this space combat game, pilot a lone spaceship on a mission to eliminate various hostile enemies including flying saucers, seekers, satellite dishes, and spinners. Utilize the top-screen radar to track enemy movements and strategically position yourself for optimal firing range. Advance through increasingly challenging waves by destroying a set number of foes. Navigate carefully to avoid collisions with enemies and shrapnel, as these will cost you precious lives. The battle continues until you clear all waves or exhaust your lives, ending your interstellar defense mission. This game offers a blend of strategic positioning, quick reflexes, and spatial awareness for an engaging space shooter experience.
