Welcome back to another speedrunning guide! Today we’ll be speedrunning to stage 4 cancer.

Okay so as soon as you wake up in the house you gotta go to the door and enter and exit the area exactly 69 times. What happens when you do this is that it teleports you to the Juul Den area. This a little known exploit, but when you purchase 3 or more juul pods it skips the intro cutscene.

This is our first step to stage 4 cancer. Now, to optimize this, you have to consume all the juul pods before you hit the convenience store for cigarettes. Normally you can only to one at a time, but if you spam the Use command on your keyboard then the animation loops and you can consume all of them at once. This should increase your cancer risk by 10%.

Now, you should be doing this while no clipping through the floor. Once you fall out of the world and respawn, you should appear in the convenience store. This is because you skipped the Welcome To School cutscene so this is the only valid respawn point. Press the pause button as soon as you respawn because there are a lot of complicated inputs here.

You should have started the game with the Book item. Equip that to your primary weapon. Unpause and press up for 3 seconds, left for 3 seconds, look at the clerk and then spam the throw command. If you did this right, a volley of books should be launched at him and kill him. Without the store clerk there, you don’t need the Fake ID item to obtain cigarettes.

Now typically you need the Lighter item to use a cigarette. This is where most speedrunners mess up. They go through the store and get the one in there. DONT DO THAT. There is actually a lighter on the clerk’s body that is much closer.

Now to smoke all the cigarettes at once, you spam the use key like you did with the juul pods. This should increase your cancer rate to 40%.

Last stop is the power plant. To get there from the convenience store you just do the same thing with the bedroom door, go in and out 69 times. This should bring you directly to the reactor room if you did it right. There are two tubes, one bringing in coolant and one bringing out nuclear waste. If you notice here, the waste tube is too far for you to reach.

If you spam the Default Dance emote it will levitate you character off the ground just enough to grab the tube. You want to rip it out of the reactor and spam the use key to consume all the radioactive material in the tube. This should increase your cancer rate to 100%. The alarm should start ringing, and many runs end when the reactor workers break in and spot you, so you have to be really careful in this part.

Again, spam the default dance emote until you levitate off the ground. You have to get onto the reactor by pressing jump at a frame perfect moment. Right… THERE! Ok so the reactor workers cutscene should NOT happen if you did it right. 

Ok next what you have to do is fall off the reactor and break your leg. If you spam the Interact key it will skip all the 911 cutscenes until you are in a hospital bed. If you pull out your book again and spam the use key this time it will let you noclip through the wall behind you into the break room. The doctor has left his diagnosis on the counter near the door.

Grab his pen and change “stage 3 cancer” to “stage 4 cancer”. As soon as you do this, all the cancer debuffs you had should upgrade to level 4. Go back through the wall and into the hospital bed and spam the interact key. The doctor should come back in and diagnose you with stage 4 cancer.

If optimized correctly, this speedrun should take you 4:20.
