Megapede (1993)

In this clone of Centipede, the player controls a spaceship, which can move freely in the bottom third of the screen, and shoots upward to destroy the oncoming snake. Scattered around the playfield are mushrooms and rocks, which can be destroyed by the player's shots. When the snake encounters one of these obstacles, it descends a row and reverses direction. Destroying a segment of the snake creates a mushroom, filling the playfield and causing the snake to descend more quickly.
