Galaxy Warrior is a space shooter with constant enemies who really want to get rid of you. Interfere with them. Avoid their projectiles and exterminate them all. You are presented with 4 different battle zones, galaxies. Each zone has its own variety of enemies. At each level of the battle, collect power-ups and coins. Upgrades allow you to make your Galactic Warrior's weapon better and exterminate more enemies, while coins, as expected, will allow you to open new spaceships and zones.
