Super Mario Land 2: 6 Golden Coins
Super Mario Land 2: 6 Golden Coins is a platforming game for the Game Boy released in 1992 and later for the Nintendo 3DS's Virtual Console in 2011. It is the sequel to Super Mario Land and also marks the debut of Wario, who would later become a recurring character in the Mario series. Like its predecessor, it received a Player's Choice and was produced by the late Gunpei Yokoi rather than the Mario series creator Shigeru Miyamoto, who was not involved in the development of this game. It is notable for having being the last side-scrolling Mario game until 2006's New Super Mario Bros., 13½ years later (discounting re-releases & remakes). Like Super Mario Land, this game was originally excluded from the main Super Mario series by Nintendo, but were included alongside the more traditional games for the 30th anniversary of Super Mario Bros.
Story from the instruction booklet
The plot, which immediately follows that of the first game, consists of Mario returning to his castle after rescuing Princess Daisy, only to find that it has been taken over by an old enemy, Wario, while Mario was in Sarasaland. The 6 Golden Coins (Mario's keys to the castle) were spread throughout Mario Land, and Mario must retrieve these coins in order to defeat Wario, reclaim his castle, and restore order to Mario Land.
The game begins with a simple "tutorial" level to help the player learn the controls of the game. This level can not be replayed. After this is completed, the player must travel through six different "zones" containing a series of levels to collect the coins:
In addition to the tutorial level, there is also another level that is not part of any specific "zone" or area, and lies off the path between the Tree Zone and the Macro Zone. Playing this level does not unlock anything, though does count as one of the exits in the game. Unlike the tutorial level, this level can be replayed.
With Wario as the antagonist, this is the third Super Mario title to feature a major villain that is not Bowser, the first being Super Mario Bros. 2's Wart, and the second being Super Mario Land's Tatanga.
Unlike the gameplay of its predecessor, Super Mario Land 2's gameplay more closely resembles that of past Mario franchise titles. Most notably, this game replaces the Superball Mario with a more traditional Fire Mario and does away with Super Mario Land's vehicle levels. The screen can now scroll to the left, allowing Mario to backtrack through levels, and character sprites have significantly increased in size, enabling more focused and fast-paced action as well as a better overall visual quality to the game. The game is one of the first Mario games to have two different difficulty levels: Normal and Easy mode. The level can be chosen by picking Mario's size with the button before picking which file to save to.
Like in Super Mario World, the game's locations can be traversed via an overworld map. This gives rise to a few secrets, including "shortcuts," which allow Mario to traverse the map more quickly, and a casino where Mario can gamble his coins to earn more lives. Unlike those of Super Mario World and the earlier Super Mario Bros. games, Super Mario Land 2's worlds do not have to be played linearly without requiring a hidden item or exit, although all worlds must still be cleared. The player can return to the world map from a completed level by pressing to pause and then .
In levels, the allows Mario to jump, while holding the will make Mario run faster. Holding up on the will make Mario jump a little higher. The controls where Mario walks or runs. The player can pause in a level with the button. Jumping on most enemies will defeat them, as will attacking them with fireballs, a Star, or hitting them with a Koopa Shell. A Koopa Shell can be picked up by running into it while holding and thrown by letting go, or it can be kicked by walking into it or jumping on top of it.
Super Mario Land 2 continues a tradition established by past games and includes a plethora of level designs. For example, there are water levels through which Mario swims by tapping (Mario can also swim through sap, and movements such as walking and falling are slowed down) and space levels with altered gravity (jump height is increased, as is fall time).
Mario can use Warp Pipes in the same manner as in other games: by holding down on the while standing on top of one, up while jumping up into one above, or left or right for pipes that are horizontal.
Rewards and setbacks
Getting hit by an enemy or hazard while Mario is in his Small state, falling to the bottom of the screen or in lava, getting crushed behind the screen in an auto-scrolling level, or running out of time, makes Mario lose a life and get booted out of the level and back to the map. If Mario loses all of his lives, he will also lose all of the 6 Coins he has collected and will have to fight their guardians once again, but he does not have to replay the other levels in their worlds to get there. Extra lives are represented as hearts as opposed to green mushrooms in this game, due to the grayscale graphics.
Each level has a checkpoint, which is a bell hanging from a block. If Mario rings the bell, he starts the level from this location should he lose a life.
The exits of regular levels are marked "GOAL" and consist of a door in the wall and a bell hanging from a post above it. If Mario enters the door, the level immediately ends, and he returns to the map and progresses to the next stage marker, but if he hits the bell first, he gets to play a bonus game which can reward him with power-ups or more lives.
Collecting 100 coins does not immediately reward Mario with an extra life like it does in other titles, but it does allow the player to enter the casino in the hill between Mario’s castle and the tutorial level for a chance to earn lives. Mario can hold up to 999 coins.
There is no "score" in the traditional sense that Mario gets in this game for defeating enemies or completing the level with extra time, but he does have an enemy counter for each enemy he defeats, and defeating one hundred enemies will cause a Star to fall down to Mario.
The Super Mushroom grows Mario into Super Mario, which allows Mario to take a hit without dying (reverting him to regular Mario) and gives him the ability to break Brick Blocks by jumping underneath them, like in previous titles, but it also allows him to perform a Spin Jump to break Brick Blocks beneath him by pressing down on the in midair, a technique taken from Super Mario World. Super Mario can destroy Koopas, Koopa Shells and some multiple-hit enemies by landing on them with it, but other than that, the Spin Jump does not have quite the same effect that it does in Super Mario World, but it will function the same way as a normal jump when Mario lands on other enemies or hazards with it.
The Fire Flower performs its usual ability, allowing Mario to shoot fireballs by hitting that bounce along the ground as a weapon, but Mario can now also use them to break a special kind of block as well. Fire Mario is recognizable by a single feather in the front of his cap in this game instead of a change in color, perhaps due to the Game Boy's limitations.
The introduction of the new Carrot transforms Mario into Bunny Mario. This gives him the ability to flap his bunny ears and hover by tapping the button, giving him the ability to stay in the air longer and cross or maneuver around obstacles and hazards with greater ease.
The Star turns Mario invincible, protecting him from harm, but instead of the power-up moving like it does in other titles, it will stay still on the ? Block. The fifth enemy killed while invincible and every enemy afterwards until Mario reverts to normal gives Mario an extra life.
Worlds & enemies
As the game's title suggests, the game is split into six different worlds, and then a final level where Mario fights Wario, the final boss.
An educational Japanese-only video, called Mario Kirby Meisaku Video, was produced in 1995 based on the game. It featured a segment based off Super Mario Land 2, and another one featuring Kirby and other characters from his series. The video follows an alternative version of the game's plot, where Wario steals treasures from a school, and after being informed by Princess Peach, Mario embarks on a mission to defeat Wario. The intent of the videos was to teach Japanese children Kanji.
Sequels & prequels
After the introduction of Wario (who quickly became popular) the Super Mario Land series shifted its attention to him. The next game, Wario Land: Super Mario Land 3, featured Wario as the protagonist, with Mario only making a minor cameo at the very end of the game. The next game in the series was simply titled Wario Land II, thus making Wario Land the final entry in the Super Mario Land series.
Although this game marked the first appearance of Wario, dialogue in the instruction booklet suggested that Wario was an old enemy of Mario who was jealous of his fame and fortune. In the comic book inspired by this game, Mario vs. Wario, Wario was said to have been one of Mario's friends when they were both children. However, because of the numerous indignities Mario (unknowingly) forced Wario to suffer, Wario swore revenge on him (which led to the events of both Super Mario Land and Super Mario Land 2: Six Golden Coins).
