Space Invaders / Space Invaders M

In the fixed shooter Space Invaders, the player shoots at the sky-high aliens by moving a laser gun horizontally across the bottom of the screen. The aliens first appear as five rows of eleven individuals that move collectively left and right, moving lower if they encounter a screen edge.
The objective is to shoot every alien in order to get rid of them. The game finishes immediately if the invaders touch the bottom of the screen, even though the player has three lives. The aliens fire projectiles at the player's cannon in an effort to destroy it. A fixed defense bunker that serves as part of the laser cannon's defense is slowly being destroyed from the top by the aliens; if the player fires while beneath one, the bunker is destroyed from the bottom up.

The game's music and the aliens' movement both quicken when they are vanquished. Once every alien has been eliminated, a lower-level wave follows, and so on in an endless loop. Periodically, a unique "mystery ship" will move across the top of the screen and, if destroyed, will grant extra points.
