EDIT: Fact #46 is incorrect. There are also one of these old broken radios in escape 01 and advanced chamber 16 as well as advanced 18. Also, I forgot to mention that you can also see these older radios on a first playthrough. EDIT #2: Should clarify that on Fact #33, the video clip shows a mechanic called ABH or A-hop (Accelerated Hopping) to gain a lot of speed. I didn't mention this in the video because this video was actually mainly intended to be watched by other speedrunners. But the fact that it has blown up and reached to so many more casual players is amazing. Thank you all for your comments. EDIT #3: Should also clarify that the glitch in fact #44 can only happen on newgame+ playthrough, as a first playthrough won't have the radio in 05 that actually triggers this glitch.

I'm dying of laughter at the game doing 10 billion damage to you over not being able to put you anywhere safe

I appreciate the fact that these were ACTUALLY obscure Portal facts. Good job.

This video was absolutely god tier. 50 facts, no messing around, clear, concise with visual aid - no stupid intro, no drawn out commentary... Perfection. This is the gold standard of how youtube vids should be done.

This video is A+ material. Source geek stuff for source geeks. I absolutely love “you know this obscure fact, but what about this even more obscure fact that’s related to it?”

1:37 bonus fact, if you die right in front of an emancipation grill, your ragdoll becomes visible and flies away t-posing

Absolutely epic vid. As someone with 2,000 hours on portal 2 but only 380 hours on portal 1, I learned quite a bit :)

5:55 That's actually because cameras are still considered as active when they're dismounted from walls. It uses that m_bActive variable to determine if it can be picked up by the gravity gun. If you dismount an inactive camera, they can be picked up. 6:13 The loose cameras are how cameras were intended to appear. The pose parameters are messed up when their model is used for the NPC.

didn't know the camera shy line was rare!! i happen to go really slowly through all the puzzles and actually don't move or start until glados is done talking lol so when i shot off the last camera she gave me the creativity line and i ACTUALLY cackled. this was a great video!!!! edited for clarification (:

Holy moly this video is a hidden treasure! No long intro, no long sponsors, no fluff, just information as soon as the first frame appears on the screen. 10/10, new sub, and instantly liked the video without being told to. THIS IS HOW GOOD INFORMATION/INFORMATIVE VIDEOS SHOULD BE PEOPLE!!!!

It's a small thing, but I always greatly appreciate when videos like this are labeled "probably" with the "don't know" part. Gives the viewer some credit to their interest and knowledge of the subject. Great list by the way, with most of these facts being new to me!

10:42 For people where this accidentally happens to, it's EXTREMELY freaky. CreepyPasta levels of creepy. I think I had it happen one time back in the day.

This game is 16 years old, and you are telling me about all of this only now? Good games never die.

This is how YouTube videos should be. 🏆

6:53 very reasonable reaction

been playing this game for almost a decade and only knew around half of these, good job

This is awesome. I hope this Pinsplash-style of content becomes a new genre of video for games

5:53 Camera: "Who's that behind me?"

What the hell i spent so much of my youth speedrunning portal it was my main obsession for years and yet some how i didn't know most of these??? Amazing stuff

This video changed my life.
