Xenome Containment Unit

Xenome Containment Units are fragile containment units featured in Metroid Prime and possibly Metroid Prime 2: Echoes as well, though in that game they are indestructible. They are featured in both the Glacier One labs in the Phendrana Drifts and the Phazon Mines. They can be destroyed by a Missile, and often contain Metroids or sometimes items. Metroids are able to break out of their canisters on their own.
