M20: Insurrection is the 20th mission in Metroid Prime: Federation Force, and the final mission on Bion. Following M19: Incursion, it was believed that the Space Pirates had more than one Transfer Device active. This is confirmed when more of the encrypted Space Pirate messages retrieved by Samus Aran are decrypted. The second machine is located on Bion, and the Federation Force is sent to destroy it.
Shortly after landing in an underground tomb, the Marines trigger a Pirate trap, and they fall down a shaft, losing their Mechs in the process as they fall further. They must retrieve their Mechs and then destroy the device, taking care not to be spotted as they are defenseless without their Mechs. A bonus objective for this mission is to be unharmed while outside the Mech. The Marines then encounter a complicated maze of lava pits and moving fireballs, and must get to the enter of the maze. Here, they will find pressure pads that, when pressed, will cause them to fall through the floor, near the first player's Mech. In multiplayer sessions, the other soldiers will find their Mechs in the chamber outside the Transfer Device room. It can be presumed that the Space Pirates took the Mechs in an attempt to reverse engineer them. Multiplayer sessions can become extremely difficult, as the suitless soldiers must take alternate routes and rely on the Mech-using soldier for defense.
Ahead of them is a slope and falling boulders, followed by a cave in which Flying Pirates attack the Marines. This continues into a corridor with lava at its bottom. Thermo Spheres, large balls of lava will jump up and impede progress, as will Fire Hoppers. After all members of the Federation Force recover their Mechs, a massive battle against a Collosun and several Elite Pirates will then commence. This is followed by more infinitely spawning Pirates in the room with the Transfer Device, which is harder to destroy as its targets are now partially shielded. Once the device is destroyed, the mission ends.

The Red Sphere born from fire must not be disturbed. Only furious retribution will come of doing so.

Mission briefing[edit | edit source]
Pre-mission[edit | edit source]
"Good news, Marine. We've been able to decrypt some additional parts of the encrypted messages that Samus sent us.
According to this new information, we've learned that there was indeed more than one transfer device. This new one is hidden underground on Bion!
It appears that the Space Pirates have been transferring energy from Bion, as well as from Excelcion.
Your mission is to search the underground tomb where the transfer device is hidden. Once you've located it, destroy the device!
Be prepared, Marine. There is undoubtedly a large Space Pirate force protecting this device. You'll need to be at your best. Move out!"
Post-mission[edit | edit source]
"Welcome back, Marine. The transfer device is a smoldering heap now, thanks to you.
Unfortunately, we still aren't detecting the DOOMSEYE weapon in the Bermuda system. Could it be possible that the Pirates have another transfer device?
The intelligence team isn't going to rest until they finish decrypting the encrypted messages.
Luckily, it doesn't seem like there's much left to decrypt. The team believes that they'll have the location of the DOOMSEYE for us very soon.
Your hard work is making this possible, Marine. I want you ready and waiting for the moment we have word of our next target."
