Complete the game to unlock Boss Rush and fight Samus’ most formidable foes one-after-another to try to get the best time possible! At the end of each battle, your missiles will be restored, but any damage you’ve taken will be carried over to the next boss fight. Each battle can add to the players max missiles, Energy Tank, and Power Bombs, depending on where the boss is in the main game.
Complete Boss Rush mode to unlock Survival Rush mode. In this mode, defeat as many bosses as possible before a timer runs out. Each boss you defeat will add a bit more time to your clock. And if you’re able to defeat a boss without taking damage, you’ll get even more time added to your clock. In this mode, missiles and health do not recover between bosses.
Complete Dread Mode to unlock Dread Rush mode. Challenge a gauntlet of 12 bosses without stopping—one right after the other. Just like in Dread Mode, taking a single hit means instant defeat. Missiles are fully recovered after each boss battle.
If you’re looking to get a little training in, you can practice boss battles in this mode. Try to defeat each boss as fast as you can. Then, you can go back and check your previous times to see how you’ve improved.
