Half-Life Done Backwards in  

FAQ: Q: Why does the HP cycle between 0 and 255 and why is is infinite? A: Valve wrote the HUD to function like that, the health is actually a great value, about 20.000 or more, which is legitimately possible to obtain via a glitch called IHD (look it up) Q: Is this run legit? A: Few in-game scripts were used (gauss boosting, some smg boosting, auto-jumping) by some runners (not all of them felt like using them), AND it's physically impossible to backtrack some areas because valve did NOT include level triggers to allow the player to return, it just wasn't intended, hence the sudden cuts and ammo replenishment (The devs of backwards mod decided it was just more enjoyable to have unlimited health and ammo in general since the challenge of backtracking was great enough). No cheat commands were used if you care. Q: Why is there no tram ride? A: None really thought about it until the video was done. Q: Why did you start the run outside of Nihilanth's arena? A: I had the idea of making a small story where Gordon decided to "undo" all events that led to that point, but eventually gave up on the idea and started the video on where it matters. Q: Is this a speedrun? A: Moderately fast thing.

The moment when Gordon realized that he didn't delete his browser history

10:42 "Hey Gordon"

didnt even return the HEV suit

Nihilanth - " Freeeeeeemaaaaa ---- " Gordon - " Shit i forgot my glasses… gimme 12 mins brah "

"Sorry, my mom came back home"

11:52 Oh, this explains how Eli lost his leg.

"Gordon, you're fired!" Gordon:

Play the video in reverse and it becomes Half-Life Done Backwards Backwards Which Is Forwards But Is Actually Backwards In Reverse.

10:43 "Hey Gordon" "Gah" "STAHP"

Storyline: After fighting through all of the Combine forces in Half Life: Episode 3, realizing that everything he has done was for naught, Gordon decides to take his destiny into his own hands and manages to activate a portal between time and space which lets him go back several years in the past, right before he has to face the Nihilant and his minions. He knows what he has to do, he has to go back where it all has started, to the Anomalous Materials section of Black Mesa and kill some key scientist to prevent the end of the world. But to do this, he has to make time revert back. How? He soon discovers that by traveling back in time some remnants of time portals have been left in his general vicinity. Once he travels through them, the environment returns to a state where it looks like he didn't intervene there in the first place. Now, it's time to take matters into his own hands in this new game titled: A Freeman in Time!

when you have done everything in 20:41 and you need go back to work

Outerloper - No One's Lair - Nex - Lambda Surface - Core relaxation - Indesputable corruption - Base preservation - Escape - Off the rail - Power down - Blast hill - We've got no hostiles - Office simplex - Foreseen causes - Ordinary materials - Black Mesa Outbound

Gina Cross: are you coming Gordon Freeman: ... Gina Cross: my parents aint home Gordon Freeman:

When you have defeated Nihilant, but G-Man didn't take you with him, and you kinda want to go home anyway

Local man undoes his destiny (while flying at mach 10).

*Reality is falling apart and I must speedrun backwards.*

10:42 "Hey Gordon... Daaah!!" My favorite kind of dialog in HL. Like when the scientists falling to their death in the elevator say hello.

I really like the casual "Hey Gordon" at 10:42. Its like an everyday occurance in Black Mesa where a scientist just blazes through the facility while shooting himself with a grenade launcher.

When you’re about to fight this baby alien fetus thing but remember you never filed your paperwork

When Gordon realizes that he needs to get his beer from Barney before he fights nihilinth

The HECU at 3:06 was like "THE HELL IS HE DOING?" on the radio.

G-Man: "Its time to choose, mister Freeman. Unless you can do the impossible and revert the flow of time itself!" Freeman:

!loof uoy nameerF

Finally, we get the explanation on how Gordon was late to work.

"Aw shit, I left the stove on."

And now , Do hl2 backwards

6:12, that shit was pretty impressive

10:43 “Hey Gordon” * distant screaming and scuffling *

Gordon ran so fast that he revert the resonance cascade and save the Earth

“Left my phone on the tram, hold on.”

When you remember that you missed a scheduled urinalysis and radiation check-up.

Gordon: “oh man I left something in the test chamber hold on guys I’ll be right back”

3:44 Clench those buttcheeks.

Scientist:"OH MY!This place is all messed! Gordon:Oh...Let me fix it! *Runs Backwards*

When you’re chilling with your alien fetus friend in a cross-dimensional borderworld and you realize you’re late for work

Would be interesting if you lost weapons once you passed the point where you would normally first obtain them.

I like how in these speedruns Gordon is moving so fast, yet reloading the weapon so calmly

If these guys ever decided to shift their priorities from speed runs to solving world problems, we'd have world peace in 25 minutes and climate back to normal the next day

This is what it's like to reject Gman's offer

can't blink, i don't wanna miss a whole level.

Only in Half Life will you find speed runs of the game forwards AND backwards. P.S: quadrazid also did a run of Half Life upside down.

6:52 "Gordon Freeman! finally i can tal-" "Nah man sorry i gotta go i left my stove on"

It’s really satisfying to see Gordon’s health at 250

"GET TOP SIDE". He says to gorden, coming from Xen.

When you are about to fight the Leader of the alien forces but you feel tired so you decide to go back to the dormitories instead

*When Gordon forgets his wallet in the beginning of the game*

Reminder that this was made for fun, we know there's a lot of time to save and it was really nice getting from something made for fun only into something incredibly fast!

Ah man, I really expected the tram part as well.

I've always found speed running, especially on Half Life 1, to be unbelievably impressive. The amount of time put into learning how to b-hop is one thing, but learning to utilise explosives, scenery interactions, timing, is just astounding. Well done to all of you who worked together to do this. One of the areas I was really impressed by was the claymore area, where one wrong move would be a game over. But yet it was approached very quickly and well coordinated. Good job to you guys and other speed runners out there.

When Gordon forgot his glasses

0:53 seems legit

_They're waiting for you Gordon. In the test chamber._

Has speed running gone too far?

Quadrazid: "am i a joke to you?"

The moment when Gordon realized that there is a limited edition of the game Half-Life 3

Ground Zero: *You could not live with your own failure. Where did that bring you? Back to me.*

when u forgot the crowbar

hey look, he is travelling through time!

Random Guard on stairs: [casually] "Hey Gordon" Apparently it's just another day in Black Mesa

Awesome speedrun, love the collaborative effort!

Damn that was sick! Do you think it would be possible to beat Xen starting with 100 HP at Nihilanth and only later using IHD for the rest of the game?

Well just like a maze. It’s done faster backwards.

I was hoping you'd also do Black Mesa Inbound backwards as well, but this was still great.

I guess that it should be called HLDWaNMoV Half Life Done With a Negative Magnitude of Velocity

When Gman asked "can u go back i forgot my case"

*Gordon starts rocket jumping around corners back the way he came* Head crab: alright what the f-

6:50 "Oh! Hi there!"

Hes done it, Gordon finally figured out how to get to work on time.

This was incredibly fun to watch.

So technically my entire childhood undone itself in 12:30

When you almost clear the game but you left the car running.

Gonna be my head cannon now that all these speedrun tricks, is how G-Man is able to get around the place seemingly otherworldly

My mouth was open the entire time Jesus u guys are the best ❤️

Gordon forgot his keys

Is your creativity endless ? LUL

Half life 3 : ... Gordon returning back in time to stop the resonance cascade accident

you are insane, nice work man!

That one guy on GTA Online who’s killing everyone on the server.

When tf2 player main soldier and demoman play half life

Gordon took one look at the Nihilanth, and NOPE'd outta there so fast, he undid the Resonance Cascade and saved the world.

4:51 Explosive boxes: "Exists" Gordon: "You do not."

Wait, so how does this work? Is this a modded version of the game with changelevel triggers at the entry point to every map?

Bestest run 😂👌

Gordon realized he forgot to check the area for personal belongings before exiting the train.

Fantastic this is beautiful

Mind boggling. Wow. And here, I've known this game for those 20 years.

As soon as I watched the speedrun in 90 minutes in 2015, there is already a speedrun from the end to the beginning. I'm getting old...

When Gordon kills the Nihilanth but then remembers he didnt blow up the microwave casserole in the break room

6:53 Casually hops right past G-man

watching this made me anxious. great job to all though!

When dinner is ready

"i think i left the water running at home"

“You know....fuck this I’m going back”

When you reach Nihilanth and realise you forgot to fk with Magnusson's casserole in order to make that scene in hl2:ep2 happen...

"To answer that, we need to talk about Parallel Universes."

It's insane how different games feel if you just play them backwards
