[@SnackPatrol]

Hey man just want to say I appreciate what you are doing with your channel. I've been playing since Beta in 2007 and your KZbin channel is the only non-goofy-SFM TF2 channel I've found that has actually interested me enough to subscribe. Interesting, well-thought out content, good editing, non-clickbaity titles, and most importantly information I was not already aware of. I wish you all the success man, and to be honest, I think content like yours is inspiring me to possibly kick off my own TF2-based content as I look to hopefully forge a career in creative endeavors.

[@RudyG.Numpad]

Honestly as a demoknight who always camps in the underworld I feel like the chaser enemy is unnecessary

[@holidaypenguin]

For a map that probably tries to kick you out of underworld before the next iteration generates, it would kinda make sense to have a NPC that forces you out. Otherwise your options for persuading players to leave are more harsh, like damage ticks that increase or an abrupt killzone over the whole area.

[@micahnightwolf]

The trigger_hurts ramp up in damage over time so you really can't stay in there for long unless you have the katana or kunai.

[@sheacorduroy5565]

Ironically, the original map, Eruption, DOES have lava, lol.

[@LEDs]

I didn't show red's last spawn room with the lava flowing down the walls, that's one of the most gorgeous parts of the map!

what if they pull a sunshine and add it in a later update? a lot of good maps that don't get added usually get their reskin added during halloween or christmas, so it's a good precedent for valve to get to know the mapper better and recognize their other works

[@nogusek5836]

Its amazing how valve has now decided to actually let the community to fully work on the game, we get the best ideas into the game, while valve doesnt have to much. A game as old as this one also deserves to get passed to its community too

[@shadycatnipdealer42069]

Honestly, I think what would really keep TF2 going would be custom community weapons added in the game. Probably require a shit-ton of begging and building good will for Valve but man would it be cool.

[@thatpumpkingirl]

@@shadycatnipdealer42069They’d most likely limit it to maybe 2-3 new weapons annually just so they can tune the new weapons so they aren’t overpowered or so weak you can’t do anything

[@ambrose3560]

Source engine has random generation capabilities? That's so cool, I wish it was utilized more often. Props to the creators for this absolute feat of modding

[@foodaah]

wish i could see a map,payload or control poin, that purely uses random generation,having dozens of variations for each point,that would be cool

[@lampenpam]

There was someone who made a rogue-lite coop map for CSGO with generated levels in an even bigger scope. It's pretty insane that it works at all, but sadly this map is no longer playable because of CS2. 3klicksphillip made a video on it.

[@CeretPenyok]

I'm not particularly interested in TF2, but I absolutely love it when someone explains how the Source engine's map works. When I read the title and it said "randomly generated," it grabbed my attention because it's amazing to see something randomized in the Source engine. I tried to randomize a prop spawn 9 years ago but failed and had to stop mapping because I needed to focus on college and then work life. However, this TF2 map has left me in awe. Now, I'm inspired to create a map again using Hammer. Perhaps I'm gonna start over.

This is definitely my favorite underworld. I was extremely impressed the first time I played it, and it didn't even occur to me just how impressive it was from a technical perspective.

[@majorjohnson8001]

I used that rain feature back when Valve did the first mapper contest (the "skin this map" one). What I did was when the first point was captured, make lightning flash in the sky and turn the rain emitters on. I *thought* I only used one particle emitter, but that was like 10 years ago, so I don't remember for sure. There were some other details I really wanted to add that I just didn't have the art skills for, like a crocodile in the kill zone under the last point, but the lightning and rain was a great detail element that was rather subtle.

[@lilumhoho8]

Such a type of map is definitely very interesting and fun-to-play, although a competitive game wouldn't be nice

[@fleggy5050]

Luckily this is team fortress!!! more specifically scream fortress!!!

[@carterklassen405]

[@Upsidedownsmile]

If you have GMOD, they have a randomly generated map similar to this on the workshop, that I assume goes on forever.

[@IlStr]

​@@Upsidedownsmileeven more - gmod have infinite maps.

[@buddyisbored2355]

Easily one of the best maps this year. Which is no small feat cause they're all pretty damn good. I found it a good break from the more chaotic pumpkin bomb and magic filled maps, hopefully Eruption comes around to stay in a summer update cause I imagine it plays near identical given the halloween items were limited.

[@augustday9483]

This makes me imagine a CTF or CP map that procedurally generates itself out of prefab pieces like this. That could be really cool.

I always wondered why it was so easy to hit dead ends in the underworld. It is NOT immediately apparent there was random generation involved. I had no idea!

[@LEDs]

I was actually told before I even saw the map that it utilized procedural generation, so I had to see it for myself!

[@Snazzysnail15]

Fun fact: this map was broken for me on launch (maybe still is) and people in game told me it was because I didn’t have half life 1 installed. Instead of any rooms in the underworld, it was just all black. The whole thing(except the starting room). So it was a void that was also a maze with seemingly random collision. I could technically see through walls but I didn’t even know there were walls at first. I could only navigate by following others but usually I got stuck on something and left behind. I couldn’t fathom how people were getting to the end, and usually when I took too long another player killed me

[@CoolSs]

as someone put it. if halloween was a one gimmick deal (like it used to be). this map should be the map to be added. i personally so sick of updates that add ton of maps that only increase the tf2 file size and no one will experience them (most of them are bad too). return to quality over quantity is needed

[@augustday9483]

I remember seeing 3kliksphillip's video about it years ago. I wonder if that project in any way inspired this map.

[@christianhagen183]

It does use vscript tho

[@Yashirmare]

Bit easier to do in csgo cause of the cascading light (the sun) being rendered in real time and the use of vscript. Granted that map has 1000's of different layouts while this only has a set of ~15 prefabs. Both are impressive just in slightly different ways.

[@LEDs]

I think the absence of vscript makes this map more remarkable

Random note, but shutter island might be my favourite movie of all time. You really should watch it

[@tychh1720]

[@annihilatedOne]

[@gabrielbuonomano]

This is amazing! I've wondered for a while if anyone's thought of using procgen (or even just random pregenerated area selection) for a TF2 map, but I never had enough Hammer experience to try it myself.

[@XradicalD]

I remember seeing this map getting passed last Halloween, it was so disappointing as the quality and theme are unlike any other. Great to see it in! I love Spooky maps but horror maps are on an entirely different level. And it reminds me a bit of Afraid of Monsters so that's a plus.

[@EmperorPrinc3]

The only problem i have with this map, is when the undwrworld opens, spawms a portal anove itself, and also stops movement. Even if you stand next to cart it will not move. Essential killing your teams pushing momentum. And just like Eruption in Competitive, Corruptions 2nd point is a strong choke hold. To many casual matches have ended early cuz a team cant capt 2nd. Add ontop of that how difficult 2nd is to cap with the cart stopping movment when the underworld is spawned. And it turns into a bad time.

Has the TF2 team ever revealed how to make TF2 looking models / textures? I always wondered how the mappers get new textures (especially rocks) that look like they were made by the original dev team.

[@Shookey]

Not to my knowledge but with such refined art direction, mimicking the style probably isn't too difficult in the hands of some talented artists.

[@LEDs]

I don't believe so. And back when I tried learning, I was struggling to find resources. To somebody who's already adept in texturing and modeling, it probably wouldn't be that hard, though.
