Alien Descender

Dive into the canyon and see how far you can survive.

A lone alien falls into the Pacific and descends through a winding underwater canyon. Steer past the rock walls, fire downward to destroy bombs, and collect red hearts for extra lives. The deeper you go, the closer those hearts appear to the walls. Is one more life worth the turn?

Alien Descender is an endless arcade game for Mac inspired by S. Robert Speel’s Sinclair BASIC original. You start with five lives and earn points for surviving each step of the descent and destroying bombs. Play in black-and-white Classicmode or in Color, each with its own high score. Four local save slots let you pause a dive and return to it later.

Controls

• Left / Right Arrow or A / D to steer.
• Space to fire. Hold it for repeated shots.
• P or Esc to pause.

Requires macOS 13 or later.
