Play a free retro space shooter in the spirit of 80s arcades. Blast the descending alien fleet, survive wave after wave, and chase your high score. No install needed.
Shoot down the alien fleet in this retro space shooter.
Space Defense captures the golden age of fixed space shooters that ruled 80s arcades. Slide your ship left and right and blast the descending alien fleet.
The fleet marches side to side, creeping ever lower while raining down shots. And just like the classics, the fewer aliens remain, the faster they move.
Each cleared wave brings a faster, more aggressive fleet. How many waves can you survive on three lives? Your best score is saved.
Aliens in the higher rows are worth more points. But since the fleet moves faster as fewer aliens remain, you'll want to balance your firing order between score and safety.
On desktop you fire with the spacebar, and on mobile your ship auto-fires while you hold the screen. You move your ship with the arrow keys or by dragging.
You start with three ships and lose one when an enemy shot hits you or the fleet descends to your level. Lose all three and it's game over, with your best score saved.
