In this SPEEDRUN EXPLAINED, we break down an Any% (No SLA) speedrun of Portal 2. This run is performed by Msushi, one of the top runners for this game. This run disallows saving and loading due to those features being able to easily break the game, and also disallows going out-of-bounds. What this run DOES include though, is tight movement (such as bunnyhopping), cutscene skips, glitches, exploits, and solving a lot of the chambers in just a few seconds. This video serves as an explanation of the strategies used by Msushi (and other speedrunners) to beat Portal 2 in under an hour.

Fullbright is more or less just increased brightness, and is something you can set up in the preference files of Portal 2. Fullbright makes it a lot easier for speedrunners to navigate dark levels, but Msushi mainly has it on for you at home since he can actually navigate the levels pretty decently in the dark. You're able to set up your preference files so that individual levels load with fullbright on, so that you don't need to go into any settings or anything when you load into dark levels.

5:08 - Your vertical velocity doesn't affect the speedlock, only your overall horizontal velocity.

12:24 - The Laser Switch Glitch (LSG) is actually what's described at 19:20, and just so happens to be often used on doors. The door thing itself is not LSG and doesn't really have a name.

12:34 - Ticks aren't the same as frames, they're a fixed interval of 1/60 of a second (0.0166s).

12:43 - This glitch isn't due to an overlap in the hitboxes, but rather a strange consequence of the fact that the door hitbox is entirely behind the portal.

19:20 - LSG isn't caused by the portal decay and laser staying in place for a moment, but rather is caused by the laser receiver staying on for a short amount of time after the laser itself disappears.

also i've included a handful of corrections to the video at the bottom of the description, be sure to check them out!

[Msushi]

wow, what a cool run performed by a skilled, handsome runner that is voiced-over by an intelligent, good-looking narrator. the SPEEDRUN EXPLAINED series by tomatoanus is truly something else.

[prgnify]

Shout outs to Stephen Merchant's extensive and prolific career, I couldn't wait to hear Tomato's next gag, and the one from 1:12:54 had me in stitches

[mrbraindeadtaco]

Really appreciated the 3d spatial ear massage around 34:20

[Kneightt]

I love the little detail that once msushi gets to the old chambers, the style of the checkmarks at the top of the screen changes with it

[AlexHecht]

Two days before Christmas and my man drops a new video?? What a legend.

[alliebean]

I had a bit of a meltdown last week and your "no feeling is final" speech came to me when I was feeling particularly desolate. Thank you tomatoanus, you've helped so many of us with your interludes, your videos truly have such a positive impact on the lives of so many

[duckmine]

It was so cathartic to finally hear you call him Wheatley during the final level.

[LisaMiza]

As always you stuff your videos with oh so many jokes, easter eggs and other silly stuff. I feel this one is extra stuffed, I love it.
I in particular _love_ the change to checkboxes for the levels when we're in the old part of aperture. Completely needless, but yet; you do it anyways. Thank you, anus <Insert giggles>. Thank you for being you tomato 😀

[daisydaswani]

I want to thank you for those little moments, the "there is a tomorrow" moments in all your vids. They help more than you'll ever know

[yousureboutdis]

My goodness, tomato’s humor blending with Portal 2’s humor is absolutely blissful. (Also I adored the alliteration)
Definitely my favorite videos to pretend to be an old lady and say “that’s funny” after every joke.

[christianbertoni]

I just wanna let you know tomato that your break in each video to let us know everything is going to be ok is something I look forward to every time I watch. Thank you for that, I’m sure a lot of people will agree.

[prohikikomo]

Wtf dude yesterday I was looking for videos of portal speedrunning, and I thought to myself "I wish Tomaroanus made a video on this" and now here we are. Kinda creepy... happy holidays!

[Cat_Sandwiches]

I love that the tick marks showing completed chambers also changed when Wheatley took over, really good attention to detail as always!

[OBH_yt]

"this is just a taste of what the devilishly designed dextrous double duty potent portable precision portal provider has to offer". 19:52

[soopFPS]

"starch proponent" at around 53:20 is so good god damn it

[tony]

that little break around 41 mins was unexpectedly uplifting. thank you. I needed the positive reinforcement a lot more than I really realized myself.

[emidemi]

Bringing the voice actor joke back to "Wheatley from Portal 2" for the final boss was such a moment for me that my brain still thought it was part of the joke and refused to accept it as his actual name. Masterfully played. Great video overall.

[Pfeifenkraut]

40:45 I chocked on my water there. Holy moly this man does not miss his inputs.

[xboxollieify]

Thanks to you, Tomatoanus, I was able to successfully to teleport my wife and child on to the moon so I don't have to deal with them in record time. They are gone, i miss them
