Starkeeper - Orbit Defense

Your star is under attack. Hold the line.

Starkeeper is a one-thumb arcade shooter. Your ship is locked in orbit around a star, and endless swarms of aliens are closing in. Slide your thumb to circle the star, and your ship fires automatically at everything in its path. Let too many aliens through and the star falls.

ORBIT WITH ONE THUMB
Simple to pick up, hard to put down. Drag to orbit, and your ship does the shooting. Keep an eye on the radar and swing around to meet each new wave before it reaches your star.

POWER UP WITH METEORS
Shoot passing meteors to grab their power: wingmen that join your formation, extra damage, faster fire, piercing shots, shields for your star and more. Every power-up lasts the whole fight, so each star becomes a light show of lasers.

UPGRADE YOUR SHIP
Spend the gold you earn on more damage, a faster fire rate and a tougher star shield. Watch your firepower grow from a single ship into a full squadron.

TOPPLE MOTHERSHIPS AND GALAXY BOSSES
Each star ends with a mothership wave. At the end of every galaxy, a giant boss arrives behind an energy shield. Time your shots to break its weak spots, bring the shield down, and unload everything you've got.

EVERY STAR A NEW FIGHT
Each star brings a new name, new colours and tougher aliens. As you push deeper, the swarms evolve, growing crystal armour and new tricks.

SAVE THE GALAXY, STAR BY STAR
Every star you save lights up your constellation map. Complete constellations to earn lasting bonuses, and chart your way across the galaxy.
