Mushroom Kingdom Fusion is a fan game with heavily modified Mario-style platforming game play, crossed over with many other video game elements and universes. Please note that this is NOT A PURE MARIO FAN GAME ANYMORE. It may have started out as such, but now, the game has a very distant relation to a Mario game.

Key features:

  • An overall dark atmosphere of the game.
  • Modified Mario-style gameplay, with SMB2 mechanics (veggie pulling, Subcon enemies) and guns.
  • A roster of playable characters, both from within the Mario universe and outside of the Mario universe. Each character will have their own unique powerup system and gameplay mechanics, adapted to fit within the Mario-based gameplay.
  • Extremely variable worlds and levels. Game worlds will feature a traditional Mario world at the beginning. Later worlds will be based off other video games. Other worlds will feature completely original levels. The plot centers around the Mario universe, with stories extending out to other video game universes and even an alternate version of our Earth.

The newest Beta version of Mushroom Kingdom Fusion, v0.4, has finally been released. This newest version contains a much more streamlined version of the game, with faster load times, smoother gameplay, and less lag altogether. It also has other features, such as improved flight mechanics, new powerups, and red coins you can collect for bonus prizes. And of course, new levels; 35 in total.

Edit: Water Temple's music is missing, if you want it download it here and put it in the music folder.

Here's a couple videos to show off some of the new content:
