Super Smash Bros Brawl 75m

75M is an unlockable stage in Super Smash Bros. Brawl based on the 75m (or Elevator) level of the original arcade version of Donkey Kong. It is one of the biggest stages in the game and a fan favorite because of it's retro look to the Donkey Kong series. There are several hazards, all which can be easily avoided. The platforms are all solid, and a character can only descend to a lower level by walking or running down. There's no music.
How to obtain/unlock:

Play 20 versus matches as Donkey Kong.
Stage info:
1. Size: Arguably the second-largest stage in the game
2. Random Elements: Elevators move up and down, as in a traditional Donkey Kong game.
3. Interactive Elements: Icons such as an umbrella or pot can be picked up, although it does not affect the outcome of the match.
4. Scrolling Level: No
5. Hazards: Balls of fire that roam up and down the stage can cause minimal damage. Donkey Kong, at the top of the stage, does heavy damage. A spring bounces at the top of the stage, causing a character to get knocked back far. Only the spring is consistent in where it moves on the stage. Donkey Kong disappears into the background at times during the match.
