Metroid II: Return of Samus is the second game in the Metroid series, taking place immediately after the events of NES Metroid. Samus arrives to the planet SR388 to exterminate all metroids, and succeeds in doing so.
This movie by Cardboard puts Spring Ball and Spider Ball to great use to compensate for the lack of items, and achieves victory in shortest time possible.
Note: This movie does not use secret worlds, also known as "select glitch".
