|This is the only non-progress related achievement in the game, and is quite a challenge to obtain. |
You have to launch parts of yourself into the attractor. Once the attractor reaches a certain size, the rest of the system will start to spiral and collapse into the Attractor. However, you have to stay well out of the way of the gravitational pull. The achievement will unlock when most of the system (apart from you) has been sucked into the attractor. You can restart the level once the achievement has unlocked. You cannot win after a system collapse. If you miss out on this achievement, just select the F2O-3 level at the menu and try again.
