Several bosses can be fought in the mode, and although the stock of missiles is refreshed between each fight, Samus Aran carries overall damage to the next fight. In addition, for each boss defeated, Samus can upgrade her stats and arsenal. \n \nTime to test your skills again, bounty hunters. The new Boss Rush mode is now available in #MetroidDread! \nTake on Samus' most formidable enemies and beat the game for the best time! The mode is available after the game is completed. \n \nA Survival Rush mode has also been added, although it differs from the Boss Rush mode because you will have limited time to take out as many enemies as possible. Missiles and health will not replenish between rounds, but each successful encounter with the boss will add time to your clock. \n \nIf that wasn't enough, Dread Mode has its Boss Rush challenge. Not only will you defeat 12 bosses, but you will also need to do so without getting hit. Otherwise, the game will be over. \n \nHowever, practice mode will be available before taking on Metroid Dread's deadliest challenge. \n \nIn February, Nintendo released a free update for Metroid Dread that expanded the game with two new difficulty modes. These included the Dread above Mode, with its one-hit-kill element, as well as its complete opposite, Rookie Mode, with its more accessible difficulty. \n \nMetroid Dread was released last October along with the Nintendo Switch OLED model. According to Nintendo of America president Doug Bowser, the positive sales provided "the best start for any Metroid game ever," and reviews so far have been overwhelmingly positive. \n \nIn GameSpot's review of Metroid Dread, Steven Petit gave the game an 8\/10, writing, "More than anything, Metroid Dread feels like returning to a cozy place after a long absence. \n \nUnfortunately, while the gameplay has been improved and new features added, Dread sticks to the formula of its predecessors. In the end, it's probably for the best for longtime fans like me. There is nothing to worry about here. We are home again."
