Orbitron Game

Plays: 3326
Category: Action Games
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. Build strategically; build non-permeable walls under your turrets, if you’re afraid of shooting them. Also, an Amplifier above a Turret is also a good idea.
