M12: Last Stand is the twelfth mission in Metroid Prime: Federation Force. The Federation Force is deployed to Bion in order to protect an important Galactic Federation research probe from being destroyed by a gigantic Rohkor Beetle. The probe is conducting archaeological research into the civilization that once inhabited Bion by creating a scan of their buried city. The Force must kill the Rohkor Beetle on a stretch of barren wasteland that is only decorated with cactus-like plants and a few crates to the side (some of which are partially buried), that can be destroyed for AUX ammo. There are also 3 caves to the sides of the area, blocked by debris which can be destroyed with Charge Shots. Each cave contains 2 MODs.
