Alright sorry for that double upload nosense! Got smacked down 10 minutes after I public'd it so theres always the risk with this one too lol. Anyhow I am in the process of hiring an editor to handle the editing on Crotoan Medical so expect videos to start rolling out more frequently about some good ole fashioned Disease Science! Heres the link for that! Thanks for watching guys! kzfaq.info/love/_FEM9neZa0b6axVv6mCSmA

video start: "I can't say l4d." 2 minutes later :says left for dead

I always thought they just clawed their eyes out either because their heighten senses made his eyesight suddenly become too much (your 20/20 is now 40/20 good luck) or, like the witch, they became photophobic and light became torture to them

0:20 "we do freerunning climbs such as freerunning" *yes, the freerunning here is made of freerunning*

8:09 cuz I'm free faaaaaaallin

Kung fu: the Chinese martial art of control over the body Karate: the Japanese martial art of standing your ground Parkour: the French martial art of running away.

I think that the hunter's screams are a form of social engineering. By screaming, they can make humans talk (calling out "hunter" , screaming back, etc.), or make distinct noises by panicking (arming a self-defense tool or running). this makes them easier to track targets using hearing.

2:23 "Will this fall snap my legs?" *Vietnam Flashbacks of that one storror jump fail*

This has made me wanna get in shape moreso than any other thing I've ever heard about exercise. Fantastic video as always!!

I was not prepared for the curious smoker at 5:22, lol. The ending was funny as well with the charger fighting the smoker, it looks so strange seeing a skinny man being hit by a giant meat club and not staggering. Anyways, thank you for furthering my need to excercise with this topic.

The Hunter was originally intended to have the power of invisibility. You're lucky Valve scrapped the idea because it would have been a bit difficult to explain it biologically in these kind of videos LoL Same for the Smoker, as he was supposed to appear, attack and disappear out of nowhere.

You should call the game "Left For Forever Sleep".

10:11 I was literally eating pizza when I heard that pizza joke and I feel called out right now.

I don't know what you said, but it is awesome. The idea of the hunters being parkour dudes is interesting. I always thought the virus just mutated them, and the other infected, randomly.

"Oh, ok. Guess that doesn't exist." KZfaq with history

I could see the hunter having unrestricted muscle contractions, and due to their reinforced bones, muscles, and ligaments they don't tear their bodies to shreds when they do so. It also makes sense that they would be able to use 100% of their lung capacity to fuel the stronger contractions with an increased heart rate. This would result in the hunter having far greater strength, and speed allowing them to jump 30ft in the air regularly as though it was perfectly normal.

The Hunter... my favorite infected. Ahh... those were the days.

I keep telling my friend about the videos getting smacked down with certain words in them but he never believes me, even though several non-related youtubers do the same thing. But I believe in you Roanoke, I'll always believe in you!

“That’s right I’m socially relevant” - Roanoke 2019

As a dude with shitty eye sight I can second what he is saying about the senses making up for lost of one sense. Like I can hear better than most

As a freerunner myself, it's always interesting to hear outside sources talk about it. If you ever wanted to, look up David Belle and the Yamakazi team, they're essentially the modernisers of the freerunning movement. Could always be worth putting into a video about Assassin's Creed, Mirror's Edge or even a Dying Light video if you wanna cover the protagonists in some light

Funnily enough, humans are actually capably of rudimentary echolocation. There's a hypothesis that prehistoric humans used this echolocation to navigate down into caves.

here was a hypothesis that the hunter's torn clothing in l4d2 compared to l4d was due to overheating. That the effort and metabolism had been ramped up so much they had to strip some clothing to not overheat and that's why the arms are exposed. After all it isn't that long after l4d since in l4d2 you can see Bill's body on a generator before the bridge

Starting with Yes yes *The feet* Mmmmm

I would like to point out that imo, his hunting state is actually the normal walk. Why? Well, you said that hearing is an important part of his kit. So his senses shut everything up about him. His footsteps, breathing, erratic noises etc. That way he can focus on things away from him without being distracted by his own body. When he crouches, is not a hunting state anymore, he is sure of where he is going and it reminds me of how a jaguar roars right after pouncing after its prey. I believe that explains the removal of the shoes too. He ripped them off to silence his footsteps. Great video! Hunter is my favorite

The lack of clothing can most likely be explained by 1. The time of infection and 2, The climate around them, LFD2 takes place in a much hotter area, so maybe they scratched it off.

Echo location makes sense. He growles while crawling, which would give off a constant signal.

I’ve learned more about the human biology in this 20 minute video then I have in 8 lessons of human biology in school.

“Ok boomer”

Can’t believe KZfaq would demonize the words “Dead”

I always like to imagine that the virus changed(or evolved) the hunters body similar to that of a caracal/lynx for leaping and its hands and feet to that of a squirrel for climbing. The way it begins to stalk before it leaps is probably it calculating on where to jump and how far prey is. They might have the righting reflex and land on there hands and feet and flex their back to absorb the shock of impact like a cat. The development of claws could be for climb surfaces without the risk of falling, as in some beta code they were suppose to hang upside down(maybe they can even rotate their legs 180° like a raccoon so they can climb down as well). I'm probably thinking to much into it lol

Here's my 2 cents on this, since I'm early I would think that aerobic enzymes like Citrate Synthase would be expressed more in the muscle of the hunter, while the Myosin Isoform of the hunter, especially in the legs, would shift towards the IIb Type, after all, adding muscle mass is but just one way of increasing strength, and I'm pretty sure to achieve such high leaps the hunter is capable of, adding muscle mass alone isn't going to cut it. Increasing the mechanical efficiency of the Calcium Pumps and Crossbridges within the muscle would explain part of why the hunter is so strong and has such high endurance, since less energy is needed to generate the same amount of force as in normal muscle, due to less energy being lost during contraction, more of which is converted to force. The falls the hunter can sustain, even with technique, is massive, and probably points to microstructure improvements in the Haversian architecture of Cortical and Cancelleous Bones, in addition to increased density and decreased Osteoclast activity, allowing bones to take massive amounts of trauma such as falls, and hey, bullets and all sorts of melee weapons too! Lastly I suspect the tendons of the leg muscles have reattached out further on the bone they are connected to, giving the muscle larger mechanical advantage, reducing the force required to jump a certain height and hence increasing maximum jump height Also, isn't it the Reactive Oxygen Species and Phosphates that caused issues and not Lactic Acid?

That intro was the most near godlike thing I've ever heard

"still around what humans can do" he says as the hunter jumps like 20 feet straight up

It's also worth noting that humans are capable of developing echo location in cases of long term blindness, no infection craziness required, but it does require training to rewire the brain.

I know this is quite late, but I want to point out a secondary reason why the hunters will scream when finding pray. Much like tasmanian devils it could be to alert other zombies to the location of the survivor, to food. Some species like to alert others of their species to the presence of food. Like ants and as said before tasmanian devils. This helps the species survive and grow as more of them get food. The hunters also appear as a group at times further driving this hypothesis as wolf's display similar behavior, (barking, growling) I thought I would share this.

Roanoke: L4D1 and L4D2. Sorry guys, can't say the names. Also Roanoke: 3:18

never thought about how the hunter could actually work, besides jumping as high as like 1 1/2 stories

I loved this video. The break down was very clear and enjoyable to watch, and i can tell you put alot of work into this video. You earned a sub from me, keep up the good work!

Holy Sh.. THANK YOU for pointing out the fact that he has no eyes, i thought i was the only one to see this. It always seemed like he clawed his own eyes out either out of pure anguish from the infection or as part of his mutation, being that he was a hunter he would hunt by smell, sound, and vibration

"-And that's right, I ' m s o c i a l l y r e l e v a n t."

Remembering my 25 point pounce days 👏 When a Hunter falls from a far height without landing on a survivor they YELP like the drop is still hurting them- I LOVE IT❤

This is awesome! I saw another video that described the hunter and how he did the thing he did but it wasn’t as extensive as this. So once again you delivered. I really enjoy watching your videos!

Since the other vid was removed Left 4 Game End

Just found your channel and it’s addicting. Keep up the amazing vids!

So good I had to share your channel with my cousin(s) who also play

The echo location thing also works for normal humans, have you seen the blind lad that can navigate by clicking?

“And some will do free run climbs, such as free running” Ah yes the floor here is made out of floor

Nice stuff Roanoke, start doing more left for dead morphology vids

thanks for being the best teacher ve ever had u pushed me through my sophomore juniour and senior year of high school love you man

Roanoke: "Okay, now just jump down towards m-" Coach: *Shoots the dangerous hunter* Roanoke: .... *Begins unloading clips into Coach*

Awesome! Love it when you upload! Quality content. Keep up the great work.

"I cant say the name" goes on to say it 3 times in 30sec. You made a mistake my man.

"Climbing obstacles such as free climbing or do free running climbs such as free running"

These kinds of videos always remind me to take care of my body. I'm not good at it but this helps

Left 4 dead videos still being made? Damn, I loved this game

I say that the reason why the hunter has the hoodie is cause do to the sun light which either makes him go blind or nearsighted and the only thing too use was his other sense's

A theory on the eyes the wind pressure from jumping would hurt and impair it and it tried to stop this but accidentally clawed its eyes out

I love your videos! The science aspect is incredible. Would you consider ever doing a series on vampires? Maybe about how they would physically function based on the lore of their respective universes. Please please please do vampires! 🥰

Are you spying on me. I was eating pizza when you brought up microtears in the muscles

I used to do parkour when I was younger with a good amount of people and I can honestly say I never seen anyone tape down their clothing or heard of anyone doing it until this video, see a fair share of jumps or flips that resulted in broken legs though 😂

0:00 I thought I wasn't going to hear that ever again!

About echolocation; Few years back, I have seen a video what has stated about some soldiers in CQC (close quarters combat) scenarios having trained themselves to do echolocation with tongue clicking. For how I can personally analyze this info: - Creating echoes in tight spaces/corridors sounds plausible - Requires the environment to be tight space with not much echo cancelling decorations/furniture - Longer distances would not make it work, since soldiers have the career based hazards for hearing due to guns - If the virus in L4D can enhance adaptibility, the hunter without having suffered from sound hazards might have adapted for listening echoes from his surroundings ...but oh well, these are just my thoughts (and I need to re-find my sources of info for clarity)... 😑

I like how Roanoke has his buddies play as the infected so he can give ‘em a checkup

The sleeves were probably torn up by the hunter in a fit of rage from the head of wearing a hoodie in Georgia

I see Roanoke, I click it’s a science Fantastic video as always can’t wait for more

When you said "ok boomer' at the beginning my phone thought I said "ok google" and paused the video to open the app while I was driving so thanks for that LMAO

ah yes parkour, the french martial art of running away

F for the first one youtube don't seem to like you. I still love your vidos.

Great video man! keep it up!

I have been waiting for this...way too long

Love this vid! Thanks! :D

i love watching your vids

Just knowing everything of how the body is able to build and rebuild muscles, fibers and everything else is just amazing. Also the feeeeet 😋

My headcanon with the special infected is about the green flu effects! Basically when you first get infected (pre transformation) its bad for you but once the transformation happens and you become a special infected the green flu works in tandem with the immune system.

Roanoke: "I gotta call them L4D and L4D2" Also Roanoke: calls them Left 4 Dead and Left 4 Dead 2 multiple times with 30 seconds

I love that he almost refers to our bodies as "meat suits". As if the skeleton is who we are. The Skeleton War is coming.

Man, i was just watching the L4D playlist and the change from the first two videos, wow

It’s so cool how the hunter does what it does and why

Speaking of Hunters, it would be interesting to see you cover the Night Hunter infected the player can play as in the game Dying Light

5:40 i see that WowSuchGaming footage. you can't fool me

Can you do the charger next plz, and keep up the work Roanoke.

Roanoke your videos scare me, keep it up!

Love that Zackazz is within this video. Always been a fan of Left 4 Dead

Tfw you made a Hunter named Roanoke before this video existed XD

MY GOD!! dude your vids are freaking awesome man. Iv followed you awhile but never subscribed but dude. GO YOU! Super excited for you and how your channel has grown. If you ever have the means to collab or something let me know

Noice video mate !

Freerunning is the most exhilarating expiration ever

I cannot believe that this content was released this day in age I live this game and play it like everyday but No one ever plays so it’s good to know that it’s still popular

Some stuff can just be explained by the hunter just being basically undead buh great vid I watched it all💯

"still kinda around what humans can do" *proceeds to jump 15 meters*

I walk more than 10km daily during my bachelor years. After graduating I rarely walk more than a few km a day, mostly using a car to get anywhere, and rarely did any extensive exercises (aka just being a couch potato). However, when I need to walk a long distance such as during my travels, my legs never really hurt that much and I could recover from sprains and fatigue within a day.
