The player is Samus and they must defeat 3 other Metal Samus's. The problem is that the Metal Samus have two stocks each, while the player has one. What makes it worse is that the player is on Brinstar Depths. Although the opponents are metal, they have a disadvantage. Metal characters weigh more and they fall faster. Their jumps also lose distance. All three Samus's won't attack the player at once.
