Super Mario Bros.

Super Mario Bros. (known as "Super Mario" in Super Mario All-Stars, Japanese スーパーマリオブラザーズ Super Mario Brothers) is the semi-sequel to Mario Bros., a game which was released for the Famicom on September 13, 1985, and on the Nintendo Entertainment System in North America on October 18, 1985. After the previous games were set on Earth, Super Mario Bros. is the first game to be set in the Mushroom World, marking the first appearances of Bowser and Princess Peach, as well as Koopa Troopas, Goombas and many other Mario series enemies.

Story
One day King Bowser Koopa, the great and powerful leader of the militaristic Koopa Troop, invades the peaceful Mushroom Kingdom. He and his koopa troop were jealous of the beautiful kingdom, and King Bowser decided to take it for himself. To do this, Bowser casts an evil spell upon the kingdom and transforms all of its inhabitants into blocks, weeds, and other odd objects. It is foretold that only the Mushroom King's daughter Princess Toadstool can undo the spell, so Bowser kidnaps her. Fortunately, the heroic Mario Bros. get wind of the Mushroom Kingdom's plight and race to its rescue.

The player takes the role of Mario, or in the case of a second player, Mario's brother Luigi. The ultimate object is to race through the worlds of the Mushroom Kingdom, evade or eliminate Bowser's forces, and save the Princess.

Gameplay
Super Mario Bros. is divided into eight worlds, which each have four levels. Mario has to get to the end of the level by jumping over various gaps and avoiding the enemies on his way. Mario can use several platforms, which sometimes fall down when Mario hits them, and stairs in the level, as well as Jumping Boards.

Enemies include Goombas, Koopa Troopas, Buzzy Beetles, Koopa Paratroopas, Bullet Bills, Hammer Bros., and jumping Cheep-Cheep. All these enemies can be defeated when Mario jumps on them. Koopa Troopas and Buzzy Beetles will leave their shell on the ground, which Mario can kick to hit other enemies with. Koopa Paratroopas lose their wings and fall to the ground when Mario jumps on them. Other enemies include Piranha Plants, the Spiny-throwing Lakitus and the Hammer Bros. These enemies are hard to defeat, and Mario has to avoid them. There are a few levels which are underwater. Underwater, Mario can swim freely from the top to the bottom of the screen. The enemies in underwater levels are Bloobers and Cheep-Cheep, and Mario has no way to defeat them.

If Mario takes a hit, falls down a pit, or if the time limit runs out, he loses a life, and starts again. The point where Mario continues depends on how far he ran through the level before dying; either from the very beginning, or at one of several invisible "checkpoints" throughout the level.

Mario can get special power-ups out of ? Blocks or, uncommonly, Brick Blocks. Most of the ? Blocks in which Mario can find these items are visible, but some are hidden and only become visible when Mario hits them from beneath. With the Super Mushroom, he turns into Super Mario. As Super Mario, he can survive the hit of an enemy one time, at the cost of turning back to Small Mario. Additionally, he can now get the Fire Flower. With the Fire Flower, Super Mario turns into Fire Mario, which allows him to shoot fireballs at enemies to defeat them from a distance. With the 1-Up Mushroom, he gets an additional life, he can also get an extra life if he collects 100 coins. With the Starman, which can only be found in Brick Blocks, Mario turns invincible for a short amount of time, and can defeat enemies by simply touching them.

At the end of each level, there is a castle with a flagpole nearby. When Mario his the flagpole, he takes down Bowser's flag and enters the castle, completing the level. The higher the spot is where Mario hits the flagpole, the more points he gets. If there are two players playing the game, Luigi's turn comes whenever Mario completes a level or dies. Luigi has no special abilities in the game that are different from Mario's.

The fourth level of each world plays inside a castle. They are usually filled with Firebars, and Podoboos may appear. At the end of a castle level, Mario is confronted with a False Bowser in Worlds 1 - 7 and the real Bowser in World 8. Mario ordinarily has no way to hurt Bowser, and has to either use the Ax to destroy the ground, causing the false Bowser or Bowser to fall into the lava, or pelt Bowser with a number of fireballs, which produces the same result and reveals the true forms of the fakes. After defeating a false Bowser, Mario frees several Toads from the castle. There is one Toad in World 1, two Toads in World 2, and so on. In World 8, Mario frees Princess Toadstool. If Mario frees Toads, they will say their signature sentence "Thank you, Mario! But our princess is in another castle...".

Modes
After beating the game, the player is given the option to start the game again in "Hard Mode", where all Goombas are replaced by Buzzy Beetles, and all enemies walk faster. In addition, some of the elevator-style lifts are about 60% their original size.
