This chapter is odd in that it only has a total of 15 levels (5 Light World levels, 5 Dark World levels, Glitch level, Light World Boss, Light World Escape, Dark World Boss and Dark World Escape). It also lacks bandages and any kind of warp zone. Despite the lack of levels, each level has a par time of 30 seconds or more (6-3X has the longest par time at 70 seconds).
To unlock the Light World boss, all 5 levels must be beaten. To unlock the Dark World boss, 85 of the 125 Dark World levels in the entire game must be beaten.
The music for this Chapter is as follows: "It Ends 2: End Harder" for both Light and Dark World levels, "Carmeaty Burana" for the boss fight with Dr. Fetus, "Escape!" for the part after the boss fight and "Hot Damned RETRO" for World -6.
The opening movie is a reference to the start of Pokémon Red/Blue on the Game Boy.

- Instead of being black and white, like other worlds, the name display for the world is white and black.
- Unlike the other worlds, the soundtrack played during this world's level select has nothing to do with the actual world's soundtrack, instead it's adapted from the Rapture Dark World music "Dr. Fetus's Castle". The music played at the opening cutscene and the glitch world music are also taken from other worlds as well. The implication, along with the naming of the music, was that the track "Dr. Fetus's Castle" was originally intended for this chapter.
- In another game, The Binding of Isaac, the harbinger Death has a similar face to that of the planet.
- You are forced to play as Meat Boy in this chapter, you cannot play any other characters.
