'''COMBUSTION''' is a [[Update 2.1|2.1]]/[[Update 2.2|2.2]] Extreme Demon collaboration level created by Cersia and Slithium and verified and published by Slithium on 11 September 2023.<ref>https://www.youtube.com/watch?v=3cTR4XUcA28</ref> The level was made in a 1.9 style, which is the way in which Cersia always designs his levels. Its gameplay contains tight timings, straight-flying segments, and tight wave sections. COMBUSTION features a dark industrial theme along with detailed decoration, frequently changing gamemodes, and Clubstep Monsters that appear throughout the level.

==History==
The first and full preview of the level was uploaded on 28 February 2023, provided to YouTube by Slithium.<ref>https://www.youtube.com/watch?v=TcbIVbjYjC8</ref> On 11 September 2023, he verified the level with 39,011 attempts.<ref>https://www.youtube.com/watch?v=3cTR4XUcA28</ref> Not long after, on 20 September 2023, Cersia showcased the level on his channel.<ref>https://www.youtube.com/watch?v=LpAlnfWTkAo</ref>
Cersia had the idea of creating COMBUSTION for years, as he originally wanted to build it in GDPS 1.9. Despite the level's layout being fully finished, the idea was abandoned. After many years, he and Slithium got together and decided to start working on this project in 2.1 instead, and it took finally took them a week to do.

==Description==
*'''0-17%:''' The level begins in a slow pace, featuring cube precisevely timing its jumps, then transitioning to a ship with convoluted straight-fly and up-and-down manoeuvres. Next comes a short ball section with a difficult wave, rapidly changing speeds and sizes, and this section ends with a ship beginning its transition to the drop.

*'''17-40%:''' The drop starts, and the player has to manouver the wave, interrupted by a short cube break. The space is narrow, featuring gravity portals, and despite the slow pace of this section, it's still quite challenging. After the wave a long ship section is introduced, but with more frequent ball and cube breaks. The ship is composed of straight-fly and tight spaces with no margin for error. This section ends with three wave, cube and ship segments.

*'''40-52%:''' There are only two main sections here: First is a UFO with precise timing and ceiling-spamming, and the second, a very long and slow ship with challenging gameplay. Before each section, there's a short cube break with several timings.

*'''52-61%:''' This section is characterized by a few cube clicks the player must execute, along with a couple more precise robot timings, and the last cube jump that introduces the player into the next part.

*'''61-78%:''' In this section, the visibility is sharply limited, it is one of the most challenging in the level. The player turns into a slow wave that has to go through narrow spaces, turning into a slightly simpler ship but with complex manoeuvres. Then comes another wave and ship section, followed by a ball with demanding timing, and the same goes to spider that the player turns into. After all of that, the visibility returns to normal, and there are two cube jumps over triple spikes the player must make.

*'''78-89%:''' This short section of the level features slow cube timing sections, wave with narrow space, and a dual portal that splits ship in two at the end. Now, only the last cube timing remains, after which the level's gameplay ends.

*'''89-100%:''' This is a minimalistic endscreen that shows the level's name and its two creators, Cersia and Slithium.
