M22: Convergence is the 22nd and final mission in Metroid Prime: Federation Force. In this mission, the Federation Force is tasked with infiltrating the giant Space Pirate warship Doomseye and destroying its Force Field generator from within. The G.F.S. Aegis creates a diversion for the Pirates, which allows a small dropship carrying the Federation Force to get near the force field, so that the soldiers can blast out and through the force field. After a number of intense battles with scores of Space Pirates, the Force continues onward.
