GG Aleste is a 1991 vertically scrolling shooter video game developed and published by Compile for the Game Gear. An entry in the Aleste series, the game follows Ellinor Waizen piloting the Galvanic Gunner space fighter craft to face against the invading Moon Child army. Its gameplay follows the same conventions as earlier Aleste titles, with the player fighting waves of enemies and bosses, while avoiding collision with their projectiles and other obstacles.
