Star Defenders is a tower defense game where you defend your mothership against waves of alien invaders emerging from a black hole. Build defense platforms, upgrade them with powerful abilities, and survive the onslaught!
GETTING STARTED
Place 4 platforms to begin the first wave. Enemies travel from the Black Hole (top-left) to your Mothership (bottom-right). Position towers along the path to maximize damage. Don't block the path completely!
CAMPAIGN MODE
Survive 30 waves of increasingly difficult enemies. On Wave 30, an unkillable boss appears — deal as much damage as possible before it reaches your mothership. Your final score is the total damage dealt!
ENDLESS MODE
Complete Campaign to unlock Endless Mode! Enemies keep getting stronger, XP rewards increase, and waves never stop. How long can you survive?
