Speed Run Extreme is a secret floor that contains the hardest obby that can be accessible in the game. This floor can be accessed by robux (30) or by chance.
This obby is a speedrun meaning you will have increased speed. This obby contains 12 hidden checkpoints to prevent cheaters from winning unfairly.
This secret floor is a bit familiar to the speed run insane aspects. At the start of the floor, the lava will slowly rise once the elevator doors open. You must be quick otherwise you will not get further into the obby at all. After making it past the first section, you are greeted with your first climb section. Do not waste anytime as that can ruin your run. Once you pass the climb section, you must parkour through some smaller platforms and climb upwards to reach the RUN! sign. If you do not reach the sign within 28 seconds, your run is already over. If you do make it before then, you are greeted with a section that is somewhat similar to Speed Run Insane. Make sure that you are still going fast! Once you get passed the section, you will have to do the last climb section, which personally I find to be the hardest part due to slope RNG. Be sure to climb quickly as after 57, the lava will head towards you quickly. You must escape through a narrow hall as fast as you can to reach one of the last three sections. In this section, it is somewhat like the old extreme that features the "Good Luck" sign on a platform. At this rate, you hope and pray you were fast enough as at the time of 1:10, the lava is extremely fast to the point where even if you make it to the final section, it will already be there. Anyways, after passing the speed run extreme homage reference, you are now at the second to last section, which can be a huge chokepoint. Be patient, but also be quick to pass it. The ending section is the same as old extreme, except platforms were buffed to where they can no longer be skipped. Let's not forget the final jump...
This floor will appear every 53 and can change based on how many players beaten it.
