Nintendo is adding more tough challenges in its breakout search action hit game Metroid Dread.

A new update for the game is now available -version 2.1.0- and it adds the following three modes to test the mettle of hardcore 2D action fans:

Boss Rush

• A mode where players fight 12 continuous boss battles, and aim for the best time.
• Any damage received is carried-over into the next fight. Weapons are fully-restored between battles.
• If Samus is defeated, players may select “Retry” to continue playing from the start of the battle they lost. There is, however, a time penalty for being defeated.
• Bosses fought in Boss Rush can be fought one-on-one at any time by selecting “Practice”.
• *Unlocked by clearing the main game a single time. (In the event that a player has completed the game before the update was released, they will be able to play Boss Rush immediately after updating).

Survival Rush

• A mode where players see how many bosses they can defeat inside of the 5 minute time limit.
• Any damage received, or weapons spent are carried-over into the next battle. Even if time remains on the clock, Samus being defeated will result in a game over.
• Defeating a boss will add a fixed amount of time to the countdown clock. Defeat a boss without receiving any damage to receive an even bigger time bonus.
• *Survival Rush is unlocked by completing either Boss Rush or Dread Rush.

Dread Rush

• The basic rules are the same as in Boss Rush, but if Samus is hit by a boss, her energy drops to zero and she is defeated.
• Bosses fought in Dread Rush can be fought one-on-one at any time by selecting “Practice”.
• *Unlocked by clearing the main game using Dread Mode. (In the event that a player has completed Dread Mode before the update was released, they will be able to play Dread Rush immediately after updating).
