Penguin Land was the first home console video game to include a battery backup save feature being released four days prior to The Legend of Zelda in the US.

The player controls the Penguin Mission Commander Overbite, who must guide these eggs down to the bottom of a frigid cavern filled with traps, enemies, and secret passages.

The Spaceship Crew eagerly awaits at the bottom of this cavern to welcome the hero Overbite and carry the eggs to safety.

The object of the game is to successfully push and drop an egg down to the bottom of a vertically scrolling cavern of ice.

Also included are point and time bonuses, egg shields, springs that let you jump higher, and ghosts that invert game controls.
