Osmos/Force

In the force levels, special motes (Attractors/Repulsors) influence other motes with a force similar to gravitation. The player has to take into account orbital physics when planning movement in order to save mass when changing course. In these levels, the game optionally assists the player with a course trajectory tool that plots the mote's course, up to a short time in the future. Force levels are complicated in various ways, including levels with attractors bouncing randomly around an area full of motes, several "strata" of bodies in retrograde rotation about an attractor, and attractors orbiting other attractors.

F1O1-Become the Biggest
In this level, there is a HUGE attractor and an even bigger circular wall that is deadly. The goal is the same as ambeint mode.

F1O2-Absorb the Repulsor
This level comtains a special mote called a repulsor and it produces a negative gravitational field around itself. Your goal is to absorb it.

F2O1-Become the Biggest
Same goal as ambeient mode. Again, a HUGE attractor and a deadly circular wall.

F2O2-Absorb the Three Repulsors
Three more negative-gravity repulsors to be absorbed.

F2O3-Absorb the Attractor
This attractor isn't so big. Absorb it to collapse the system.

F3A1-Become the Biggest
Like a usual Force Become the Biggest level.

F3B1-Become Huge
Many attractors in a smaller area.

F3B2-Become Huge
Larger space, less attractors.

F3B3-Become Huge
Giant space, rare attractors.
