The Force Ball is the final upgrade in Metroid Prime Pinball. It is acquired during the fight with Metroid Prime, and is used to damage the creature. Once Samus Aran has the ability, an orb of spiky green energy will appear occasionally on the map (in the Impact Crater two orbs are always present). If Samus collects the green orb, the Morph Ball will take on the physical appearance of the orb on the outside and become highly damaging to the touch for enemies, similar to the Death Ball. This upgrade is unique to this game.
