Space Invaders Infinity Gene — The game starts with the classic look of the original Space Invaders. However, this soon gives way to Charles Darwin's theory of evolution, setting the tone for the rest of the game. At the beginning of the game, the ship has general controls that allow you to move left and right and shoot. However, as you progress through the game and earn "genes", the game evolves, introducing new aspects such as the ability to move the ship in all directions.
