## What is Retro Galactic Siege?

THE GALAXY IS UNDER SIEGE. ONLY YOU CAN STOP THEM.

Galactic Siege is a pulse-pounding arcade shooter that reinvents the classic invader formula with 12 unique galaxies, 5 epic bosses, 11 power-ups, and cinematic boss intros. Built for iPhone, iPad, and Mac.

BASE GAME FREE 

12 GALAXIES Each with its own visual identity: nebula patterns, star colors, and atmospheric lighting. From the warm blues of the Milky Way to the pulsing magentas of Omega Centauri.

3 LEGENDARY BOSSES
- The Guardian A swept-wing interceptor with twin cannons and a glowing cockpit visor.
- Void Emperor A claw-shaped destroyer with dual reactor eyes and blade-wing extensions.
- Omega Mothership The Starcrusher Class. 8 thruster engines, 4 animated launch bays, and twin weapon pylons. The most imposing boss in the known universe.

8 POWER-UPS Scatter Shot, Plasma Laser, H-Bomb, Rapid Fire, Force Shield (blocks 3 hits), Black Hole, Time Slow, and Extra Life. Each with unique visuals and sound effects.

COMBO SYSTEM Chain kills for bonus points. 5+ kills triggers a multiplier.

REVIVE SYSTEM When you fall, a 9-second countdown lets you revive and continue exactly where you were with a triple shield activated.

TOUCH OPTIMIZED Precision controls built for iPhone. No drift, no stuck buttons.
