Aurora Unit 313

Aurora Unit 313 is the final boss in Metroid Prime 3: Corruption.After a somewhat easy battle with Dark Samus,313 is possesed by Dark Samus and is then a boss.

Battle 1
The Aurora does a series of attacks,mostly launching 3 Dark Samuses that do some attacks from the actual Dark Samus and then launches 2 tentecles and a few robot "eyes".If a tentacle is hit,it will leave a vulnerable spot for a few seconds.If an eye is hit,the Aurora will slam to the ground and become stuned.This also happens when enough damage is inflicted.When it falls,its latch must be grapled open to reveal its weak spot.After Aurora 313 is destroyed,it will switch forms and become a flying head.

Battle 2
The head has to major attacks:firing lasers and then immediately landing and spins itself around the areana.Both of these leave the Phazon bruise on its neck vulnerable.After enough blasts into the bruise,the game is completed.
