WOW

WOW is an upcoming 2.1 Extreme Demon collaboration hosted by TrusTa and decorated by Pennutoh, ChaSe97, Failure444, SlimJim, and Marwec, and set to be verified by Npesta, as Trusta was the original verifier, but dropped the level. TrusTa created all of the gameplay and some creators helped him decorate some parts. The level is very spam-based as the song is very fast.

History
On August 15, 2017, TrusTa uploaded a video simply titled “wow”. It showed the beginning of a layout created by him. It gained some attention and was quickly praised for its hyper-actively fast-paced gameplay and unique song.

About a month later, on September 16, TrusTa uploaded the full layout to YouTube, showing the rest of the fast gameplay and song. In the description, it showed the team that was to decorate the level. It had some decently well-known creators such as Loogiah, Vlacc, Dudex, ChaSe97, Namtar, Codex, and Aquatias.

Pennutoh released a video showcasing his finished decoration of the beginning of the level on November 12. It featured lots of color flashes and was overall rainbow-themed.

On December 3, TrusTa released an official preview of the level, showcasing the aforementioned decoration by Pennutoh and some new, never-before-seen gloomy rainbow decoration by ChaSe97 during one of the slower parts of the level. Also, the video description revealed the new decoration crew of the level, with it being Pennutoh, ChaSe97, Failure444, SlimJim, and Marwec.

Marwec released his decoration of the level on Christmas Day 2017, with it being at the last part of the level. It has similar decoration and a similar style to that of Pennutoh.

After a period of inactivity regarding the level, Salaxium released two videos on March 12 and 13, 2018, both of which showcased SlimJim's unfinished decoration.

On June 22, 2018, Failure444 released a video showcasing the finished decoration of his part of the level. In the video description, he stated that his part contains ~45,000 objects. Five months later on December 24, Splash released the end logo of the level, which he and ChaSe97 worked on.

On February 12, 2019, TrusTa began verification of WOW and achieved 22%. In the video description, he stated that this will be the final thing he is doing in his career. Just one week later on February 19, he made a start position run of 34-82%, thus mastering the spam parts. However, about a month later on March 22, TrusTa dropped WOW and passed it to Npesta, who quickly achieved 31% on the same day. The next day on March 23, Npesta achieved a start position run of 62-100%, thus mastering the spam parts. Sometime later on April 5, he achieved a great start position run of 30-100%. Just four days later on April 9, he got an astounding record of 66%. Two days later on April 11, he got an incredible record of 88%.

Gameplay

 * 0-17% (Pennutoh): The level starts during the buildup to the drop with an auto cube section with some jump orbs required to hit. At the drop is some extremely fast-paced triple-speed gameplay that contains tons of spamming, straight fly, timing, and more.
 * 18-30% (ChaSe97): Next, the song and the gameplay both slow down. Starting at normal speed and then half-speed, the part contains some cube and robot sections that require some timing. When the speed increases to double-speed, the gameplay starts as a brief straight fly, followed by a cube section with lots of jump orbs. A long and tricky ship sequence with varying gravity and sizes is next, with a one-jump cube right after that.
 * 31-61% (Failure444): Afterwards, the music starts speeding back up. It starts with some more spamming and timing-based fast-paced gameplay, this time at double-speed. A triple speed ship sequence mostly consisting of a straight fly is next, with a fast-paced near-auto cube coming right after. When the music speeds up, the gameplay does too, with some very fast triple-speed gameplay with many jump orbs and portals forcing the player to use pixel-perfect timing while also in a spamming fashion.
 * 62-82% (SlimJim): The next section features gameplay very different from other parts. It contains lots of ”spamming counters”. Here, the player must spam their mouse more than the amount of the original number on the counter to pass the part. There's many of them here, and can be very tricky for some.
 * 83-94% (Marwec): The final part features some similar spamming, timing, and skill-based gameplay from earlier in the level, along with some swing copter sections at the beginning.
 * 95-100% (ChaSe97 + Splash): Afterward, the player enters an auto half-speed cube section with the end logo. Then, the level ends.

Trivia

 * The level is the first collaboration hosted by TrusTa.
 * The song of the level is not on Newgrounds. Due to this, WOW will need another song to be featured.
