Nightmare Effects[edit]
New to X6 are the Nightmare Effects. These function similarly to the stage alterations in X1, but instead of making certain stages easier, it makes them harder. Every time you enter and then exit a stage (by beating the boss, getting a game over, or leaving a stage you've already cleared), one or more of the other stages will be altered to become more difficult. These seem random at first, but each stage has a set effect on the others, meaning the effects can be manipulated. For instance, if one wants to remove the darkness in Amazon Area, they can simply go to the Inami Temple and replace it with rain.
- The Amazon Area (Commander Yammark's stage): Adds metal insects to the Laser Institute and Magma Area.
- The Central Museum (Ground Scaravich's stage): Adds colored crates to the Recycle Lab and Laser Institute.
- The Magma Area (Blaze Heatnix's stage): Makes magma rain appear in the North Pole Area and Weapon Center.
- The North Pole Area (Blizzard Wolfang's stage): Adds ice to floors in the Recycle Lab.
- The Inami Temple (Rainy Turtloid's stage): Makes rain appear in the Amazon Area and Central Museum.
- The Recycle Lab (Metal Shark Player's stage): Adds metal blocks in the Magma Area, Central Museum, and Weapon Center.
- The Laser Institute (Shield Sheldon's stage): Adds evil soul bodies to the Inami Temple and the North Pole Area.
- The Weapon Center (Infinity Mijinion's stage): Reduces visibility in the Amazon Area and Inami Temple by being much darker.
