Ing Hive Temple Key 3 is the final Dark Temple Key required for access to the Hive Temple in Metroid Prime 2: Echoes. Samus can obtain this Key in the Aerial Training Site. However, it is obstructed by an impenetrable force field. To obtain the Key, Samus must enter the room from Central Hive West Transport (requiring the Screw Attack due to the presence of Wall Jump Surfaces), which takes her inside the shield. Once the Key is collected, the shield disappears permanently.
