Описание Cosmic Ark
In the first stage, the player must fend off meteor showers from all four sides of the screen by pushing the joystick to fire in the desired direction. The second stage requires the player to pilot a shuttle to a planet and use its tractor beam to pick up life forms. While near the planet's surface, planetary defenses will fire at the shuttle. If hit, one previously captured specimen will be freed, forcing the player to retrieve another. After a set period of time, a klaxon will warn of renewed meteor activity, and the player must return immediately to defend the ark.
