Maybe people are saying “it’s alive” because all those big yellow, translucent pipes that run through it have veins on them, and they kind of undulate or sway back and forth. You get a good look at them while you’re riding the second “cart” in the citadel chapters. There’s also a better view of them on the HL2 menu screen from inside the citadel. Anyway, my take from this was that it’s not the citadel that’s alive, but rather the technology that powers it is. Think like the rat powered consoles in Alyx. It appears as though the combine have organic powered technology. So maybe that’s it?

[@erikbrand6682]

that’s how i always took it. there are organic aspects of the citadel, however the superstructure itself is not alive!

[@sgas]

Are you sure rat is the correct word for the console power, I never say any rats in the consoles

@@sgas check again next time you play HL Alyx (or watch gameplay) - there's rats and other biomass in the consoles. You see them start to breathe and twitch when you align the node/disc with the energy beam. Fun stuff

[@F1stBr34k3r]

@@erikbrand6682 The whole point of Xen is that the flora is literally flesh, which is why Headcrabs are attracted to humans but not necessarily to Vorts. Headcrabs are herbivores in the context of their own habitat, and the grim reality is that humans evolved to be of the same material that headcrabs feed on. The Combines are probably using flesh flora in the same way the Nihilanth powered his own Xen Tech (alongside Vort Essence).

The Citadel interiors were inspired by the 1954 film "Forbidden Planet" during the tour on the interior of the Krell Power plant.

[@Nexmury]

I think people theorized that the Citadel was supposed to be "alive" because of some of the beta sfx that people have gotten ahold of. It might just be due to the uncanny and unnerving nature of these sounds, which led to people saying that maybe the citadel was supposed to be some sort of sedentary creature. An interesting theory for sure, but it's hard to say whether that was actually the case, since it's really only the sounds that give any sort of "evidence".

[@insertmemorableusernameher6795]

I think its also cause theres a eli maxwell voice line talking about particle storms that says "theres an intelligence in there somewhere" but someone cut out the part about particle storms so people thought it was about the citadel

[@tlpa]

Also the citadel in the concept art looks very "veiny" and looks as if it is either organic/covered in organic material

[@commanderpeanut8029]

Well in the retail Half Life 2 the citadel has veins, so it's not "alive" but it has organic elements and tech complementary to the metallic tech.

[@RolandVonRose]

I mean from a logical perspective the citadel moves in a very organic way. It is in the combines nature to adapt alien biology into their computers and structures, so it is not that much of a leap that the citadels core could be a life form itself or at least have one at its core. Look at the rats and other bio Materials inside the computers in half-life alyx The citadel also seem to “breath” and what I remember to be non mechanical sounding noises in its ambiance. I don’t know where the idea sourced from but the feels right, at least thematically it makes sense. The combine views itself as a giant single organism. To them we are all just cells or at best an organ. I see the stalkers as the personification of that idea. Just a mindless cell filling its role in the great organ of the citadel.

[@2Potates]

I always assumed the rat getting in the bio computer was an accident and they just didn't bother to fix it.

[@Niyucuatro]

@@2Potates Whether an accident or not. It is istill a bio computer. The whole citadel might be made like that.

[@allieanarchy2833]

I like the retail citadel the most, but it may just be because of the level of polish it got. By fading into the sky and the ground, getting lost in the clouds and smog, it becomes very hard to get a real scale or position of the Citadel and its oppressiveness almost seems otherworldly. It also gets 'hyped' by sheer omission: this massive obelisk that doesn't get recognized much at all outside of Barney commenting on it "lighting up". An omnipresent marker of alien dystopia is such a fact of life that it needs to do something special for anyone to bring it up. In terms of aesthetics though, I really wish the tile-heavy, very organic iterations got more exploration. It wouldn't fit retail Combine, but it's striking enough to carry itself in a separate IP.

[@snakefoolery2177]

Also what I think many people ignore about the citadel is that yes, its tall, but its deep we only get a glimpse of it in retail but it goes down for miles maybe even to the earths core.

[@kossa_maneka315]

My take on the "Citadel is alive thing" is that the sounds we hear inside the Citadel sounds like breathing. While it's cool and enigmatic to speculate about this I think it's the wind going through the big "hole" on the side of the citadel or just combine machinery working to keep the citadel running as we hear in the game other combine machines make non human and unknown sounds so that might be it. By the way my favorite design is the retail one. It really encapsulates the alien empire and feels really towering to me maybe because it's much skinnier than the beta one. Keep up the good work Radiation Hazard!

[@vladimirmuca849]

Such is often the nature of beta content, our imaginations can fill a lot of missing details without being restrained by things like good game design, budgets/deadlines, or hardware limitations of the era. As much as I love the grim, darker tones of the earlier art, it would be very presumptuous to say the final product would have been improved if valve stuck with that direction.

As usual a interesting video but to be honest: I'm glad that they changed the design of the Citadel and the general aesthetics of the game after the Leak. In my personal opinion, the Beta had a very generic "LOOK THE WORLD IS LIKE 1984 AND BAD ALIENS HAVE CONQUERED THE WORLD" while the Retail Version is much more subtle about this.

100%. Beta was really generic, overly dark & oppressive, and looked like it would have been just a miserable setting for a game, not at all fitting in with HL1 (or Portal). The HL2 we got is vastly superior, subtle & realistic in it's depiction of Combine occupation, grounded in the everyday normality like HL1. Glad they eventually went back to a game that feels perfectly half life, rather than mimicking generic brown fps games that were all too common in that era & beyond.

[@trekker105]

As far as the citadel being alive, I recall Barney refers to it as an entity unto itself at least once or twice (the only one I can remember clearly is near the beginning of the game when he says it's acting weird and he's never seen it stirred up like that before).

[@canadianblt8667]

"Hey Gordon! The Citadel's on full alert, I've never seen it lit up like that before! Get out of City 17 as fast as you can Gordon." Probably what you recall, just after the teleport misadventure in Kleiner's lab.

[@Immort4l5]

The “The Citadel Is Alive Theory” has been around for a while, people say that you can see blood coming from the walls of the citadel in concept art and things like that, in the beta you can also see a metal heart lookin thing apparently (I haven’t played the beta, this is from the theory), in the full game you can see these weird green vein lookin things too, honestly, I believe it I had an idea for a Half-Life 2 Beta sequel, like an episode 1 but in the beta universe, where at the end, Gordon and Alyx are escaping like they do in episode 1, but instead of the citadel exploding, it just starts bleeding out, it begins spraying out of the citadel from every side until the entire city is covered in blood, I think it would be a terrifying but great scene

[@6l1t3h_Official]

That would be cool.

[@mabs9503]

There's a lot of aspects from the Beta I wish were kept but I can't say that I feel the same about the Citadel. The one we got is great.

[@TheRealRobertBlarg]

Great video! My two favorite Beta Citadels are the one you mentioned as your favorite and the shinier more alien one. But they all have their pros and cons -- I had never seen that castle-like one, whoa! Someone should make a self-contained level set there and instead of being the Citadel, it could just be another Combine facility. I've been creating a sort of "HL2: Extended" playthrough idea which essentially takes base retail HL2 and, well, extends or expands it with various Beta or other elements; not a mod, just a playthrough where I'd play retail HL2, then occasionally switch off to other things. For example, Lost Coast will take place sometime during or between the coastal maps H17-Sandtraps. Lost Coast itself will utilize both a cut extended opening with additional Fisherman lines, plus the prettier official release. From there, that leads into the Mission Improbable mod which leads into the Lost Industry 2 mod and then back to retail HL2 to finish off the journey toward Nova Prospekt. But with this pseudo-project, I'm also utilizing all the various Beta-styled mods like Dark Interval or Raising the Bar Redux -- at least the stuff that doesn't outright conflict with retail HL2. So that means there older version of the teleport incident at Kleiners' WON'T be used... but the various levels exploring the grittier more ominous City 17 WILL be used since that's easier for me to justify as being simply different sections or districts -- the children making Cremators will be the last generation of humans essentially since retail has the Suppression Field. As a result though, there are several different depictions of the Citadel which obviously does conflict. My solution? The Citadel already has moving sections even in Retail so my idea is that for any mysterious reason, sections will shift and spin and rise or lower... thus explaining the various different looks of the Citadel when switching off between Retail, RTBR, DI, and other mods haha

[@gabrieltiberius1076]

The thing about the Citadel being alive, as far as I know, is just a theory. The reason it's because in hl2, the citadel has yellow veins with capillaries in it, really similar to the circulatory system of an animal. You can also kinda see these veins "breath in and breath out" when you are close to them. Also, I remember reading some ppl saying that some sounds that you hear in the citadel sound like breahting sounds or whatever. I dont know about this theory, sounds interesting, but it basically says that the Citadel itself is a synth just like a strider, a dropship etc (the only difference being that it acts as a static tower instead of a vehicle or weapon).

[@beaniest9210]

There was some cut sounds that hinted it was breathing or trying to speak (according to the comments of the video, I believe the video was called "Cut citadel beta noises" or smthn like that.

@@chocofrolik834 No, it was an ad interim sound that was briefly indited off as "trans" (transition).

[@nfwrambo]

Others have mentioned the citadel’s veins but I would also like to point out how the announcement system seemingly gets “sick” in episode one. I imagine that the citadel is a horrific abomination of flesh and machinery like almost every other combine synth Edit: also the 2002 citadel looks like a vape pen

A list of the versions here present and their timestamps: 1. 0:32 - Dystopian Citadel. Present only in concept, no 3d model. 2. 1:40 - Rusty Citadel. First one to have a 3d model and be present in maps. 3. 2:55 - The one with shapes attached. Used between 2001 and 2002, actually has two shapes one tapering and another thicker. 4. 3:40 - Shiny citadel. Used in E3 2002. 5. 3:58 - Hole Citadel. Present between 2002 and 2003, very similar to the retail one but with an even bigger hole in the middle. 6. 4:23 - Clamped Citadel. Looks like a castle, used in map proto_docks.vmf. 7. 4:46 - Retail version. Personally, I'd have to say the clamped citadel is my favorite, actually looks a citadel, also looks the most robust to attacks.

The notion of the Citadel being alive are the big yellow tubes that run throughout it. If you look closely at them, it looks like they have veins running around on them. As such, the implication is that they're of a somewhat biological nature.

The retail version always gave the best impression that the citadel was portaled in from the Combine empire, straight into the Earth if you remember that theory. It's angular, sleek, and I love what Valve did with the interiors. That said, I never thought it looked "menacing" enough. It's ever present and looming, and perhaps its efficiently crafted exterior says more like these things were mass produced thus making it more menacing that way, but the first 3D design and the cylindrical one really do it for me. Thanks for this presentation. I wish you had shown the maps more, but it's fine. What was the music? From the beta soundtrack?

I believe the misconception of the Citadel being alive comes from a snippet in Raising the Bar that sort of got out of control, From the book, page 190: *Combine Technology* 'Early visions of the Combine wall had it devouring the City over the course of the game, an ominous metal monster that constantly reconfigured itself as it advanced.' While I'm not 100% sure if this is the reason why it's viewed this way, it's certainly a guess on how it grew it's own legs and became 'Living Citadel!!!'.

"The Citadel is Alive" source is something Mark Laidlaw said back in 2000 at the same panel where the "Get Your Free Tvs" map was revealed. This source state "I wanted Half-Life 2 to feel different from what I did withthe story of Half-Life 1. I wanted the Citadel to be more Alien and more Alive." -Mark Laidlaw. There was also a saying by a few employees at Valve that said "The Citadel was a living creature" or "The Citadel has something moving inside it".

C17_inner was used for the concept art where Gordon stands near the entrance of Citadel at 0:40. It seems "rusty citadel" could have been in-game incarnation of the "concept citadel" or derived from it. I wish we got C17 / citadel maps from 2000, when the whole City 17 idea was created. Also, if you look closely at concept art with a citadel wall at 0:53 you can see Gordon scaling its wall with a rope - a mechanic which is absent from the game.

The original citadel design you see at 2:00 is nearly identical to the model of a brutalist monument that stands outside of the central train station in Sofia, Bulgaria. The monument is quite tall and towers over you ominously as you exit the train station. Viktor Antonov, the guy who designed the citadel, was born and raised in Sofia, Bulgaria, and has stated in interviews that City 17 is heavily influenced by his childhood memories in Communist Sofia, and fusing that with the idea of an alien invasion happening in that city.

Had that been altered slightly to fit the final product, I could definitely see it in retail, and the retail interior would just fit it, too.

To be honest I like the retail version the most. It’s less stylised, and looks the most utilitarian. It isn’t trying to be scary or imposing, it is meant to do it’s job efficiently and its efficiency makes it terrifying in its own right. The combine doesn’t care about you or your feelings so it doesn’t bother to make it scary.

[@Noxx55]

I don't know if the theory that the Citadel is alive predates Half Life: Alyx but the reason I'd make that assumption is [mild spoilers for HL:A] when you hack the combine consoles it's revealed that the "computing" is done on brain like, small cylinders made of assorted biomass. Implying under all that sleek metal is something that could be considered living.

I always thought the citadel was alive because of the veiny tube things in the retail title screen background map. Why would the citadel infrastructure need veins o.o

3:42 my favorite version of the citadel, its just so menacing and alien

[@unoriginalperson72]

Imagine the 2002 citadel with postal and postal redux ambient sounds and the sounds from the level screens

Sorry for being too late, but what music do you use in this video, Radhaz? Also thanks for the great video!

[@fantastikboom1094]

The citadel have veins in it, that's why many people saying citadel is alive. Obviously, the source is: the game.

[@dabogabo]

I think that if they kept the original interior design, the shiny one with the red Combine logo would've fitted best.

[@toprocket8556]

I like the full release and the beta that’s in between 2001 and 2002 Those are my favourite ones

[@yugoslavia_operator128]

Concept one prob looks the coolest, it is like it truly is synth place of power, the one at start is like just scraps together. And the last one is coolest one

[@Dusthandle999]

Hmm All of them are atmospheric in their own way

[@IvanIzWorthless]

Great, thank you, this goes to my future beta lore book.

[@HazarDouche]

People talking about the citadel being alive is probably because of its weird expansion in half life 2 i remember something like that that the walls come a bit forward

[@dymaxion3988]

Ever since I became aware of the manga “Blame!” I’ve wondered if people on the HL2 team were inspired by it. It was published from 1997-2003, so it lines up…

[@demondeity9816]

It's those yellow translucent pipes within the citadel, they have veins running through them. It just suggests that there are biomechanical elements to the citadel.

[@TheManWhoSoldTheW0rld]

The citadel is the most unknown and creepy thing in the beta

[@SaimizZ]

God, all of these look so good

[@quakethedoombringer]

While I like the Citadel as it is now, I wonder what it is like if Valve follows the original concept and makes it an organic living being

[@ripoutyourprejudice]

I love the early concept art for the game. Reminds me of "The City of Lost Children".

[@sanctumscream372]

I might be the only person who likes that E3 2002 Citadel. While I think the retail design is the superior choice overall, that E3 2002 one just scratches a certain itch. It's certainly not as oppressive or threatening-looking as Combine architecture probably should be, but it's the first one that feels truly gigantic. And I'm fond of what looks like the giant floodlights that illuminate its exterior. And also, the Combine clamp symbol visible near the peak of the tower. It reminds me of the kind of buildings I would see in my dreams, along with the interior of the late 2001 Citadel. So yeah, not the greatest design, and I acknowledge that, but I really do have a soft spot for it.
