KNOW YOUR MISSION
A little strategy. A lot of laser fire.
Build your advantage
Catch rapid fire, double lasers, triple shot, shields, hull repairs, and slow motion. Boss victories upgrade your reactor for the rest of the run.
Keep the chain alive
Enemies earn 100–300 points; bosses earn 2,000. Chain 3 / 5 / 10 / 20 kills for 1.5× / 2× / 3× / 5×. A sector clear adds 500, plus 1,000 for a perfect hull.
Power-ups and scoring rules
R · Rapid Fire 9 seconds of faster shooting.
II · Double Laser 12 seconds of paired lasers.
III · Triple Shot 9 seconds of spread fire; takes priority over double lasers.
S · Shield Absorbs three hits, up to 14 seconds.
+ · Extra Life Restores one hull unit, to a maximum of five.
T · Slow Motion Slows enemies, hazards, and hostile fire for 7 seconds.
A kill every 4.5 seconds sustains your chain. Hull damage resets it. Basic / scout / tank / zigzag / bomber kills earn 100 / 150 / 250 / 200 / 300 points before multipliers. Rapid Fire combines with either weapon; repeat pickups refresh their timer. Each boss upgrades your reactor by 5%, up to 15% faster firing.
