The classic arcade defense, rebuilt to run entirely in your browser. Slide your cannon, blast the descending fleet, dodge their fire, and survive as the swarm speeds up wave after wave.
Keyboard: ← → or A D to move · Space to shoot · P to pause.
Touch: drag anywhere on the play area to move your cannon; tap to fire.
Clear every alien to advance a wave. Bunkers shield you but crumble under fire. Don't let the fleet reach the ground.
