Pilot your spaceship through two waves and two boss fights — defeat each boss to restore your health and advance, surviving increasingly brutal attacks across Wave 1, Boss 1, Wave 2, and the fearsome Boss 2 with dual mini-guns, shockwaves, homing spread missiles with splash damage, 8-way missile bursts, and a deadly Phase 2 at 60% HP where attacks speed up and combat drones are periodically deployed!
