Space Invaders Browser Game – Defend Against the Alien Grid
Space Invaders Browser Game recreates the arcade classic entirely in canvas. A grid of aliens marches side to side, stepping closer every time it hits a wall. Slide your ship along the bottom and fire upward to clear the formation before it reaches you.
About this game
Move with the arrow keys or A/D and fire with Space. Clearing every alien in a wave starts a faster new wave, so the challenge escalates the longer you survive. Aliens shoot back at random; getting hit, or letting any alien reach your ship's row, ends the run. Score climbs with every alien destroyed.

Common use cases
- Relive the original alien-shooter arcade formula with zero install.
- Practice quick left-right aiming and shot timing in short arcade sessions.
- Chase a personal high score across escalating waves of aliens.
Tips
- Clear a column at a time to open safe lanes for your own bullets.
- The formation speeds up after every row drop, so don't let stray aliens linger at the edges.
- Keep moving instead of camping in one spot — alien fire is aimed at your last known position.
FAQ
How do I win a wave in this Space Invaders browser game?

Do the aliens get harder over time?
