Cleavage is the last level in the normal mode of Space Invaders Infinity Gene.
At the beginning of the level, Neurons start appearing and then Lusts will come as well. The enemies will grab the atoms or cling onto you, slowing you down, afterwards tight Shutter spaces will start to appear. After the tight spaces Nameless will appear.
- After the tight spaces, for a short time you can see the sphere that appears in the logo of the game and in the background of the Nameless fight, suggesting Cleavage takes place on the surface of said sphere.
