Run. Jump. Bend gravity to your will.

Defend your Orbit by building up an impenetrable stronghold and hold back the enemy waves!
Inspired by Space Invaders and Tetris, Orbitron is a mix between a shooter and a defense game. Prove your shooting and defense building skills in 34 challenging levels!
Tips:
Focus on staying alive rather than chasing down every enemy; Your Orbit has 40 lives and can be easily repaired, while you only got 3.
Only killing will earn you money; so don’t just build walls and let the enemies collide, you will soon run out of money.
