Space Invaders
Command your ship at the bottom of the screen, shoot down rows of descending aliens, and dodge their return fire. Survive wave after wave.
Play NowAbout
The classic arcade shooter brought to your browser. Rows of alien invaders march across the screen, inching downward with each pass. Your mission: eliminate every last one before they reach your position.
Each wave brings faster aliens, quicker enemy fire, and more bullets to dodge. Aliens at the top of the formation are worth more points, rewarding precise aim. If the invaders reach the bottom or an enemy shot hits your ship, the battle is lost.

Difficulty
Each wave increases alien movement speed and firing rate. Enemy bullets travel faster in later waves, and more can be on screen simultaneously. Destroying individual aliens speeds up the remaining group.
Scoring
Points depend on alien type and wave number. Top-row aliens (red) are worth 30 points, middle rows (gold) 20 points, and bottom rows (green) 10 points — all multiplied by the current wave number. Your personal best and last five scores are stored locally in your browser.
