It was when I rebalanced all the mutations. For unutterable I reduced the health of special infected but increased their spawn rate.

On the Unutterable video it says it was done on a legacy version? what's the difference between Current and Legacy versions?

Yes.
Pandemonium difficulty:

Do you have a link to these unutterable and pandemonium clears? i am quite curious on how anyone does it.

Lmao thank you for reminding me of that. It is even funnier now that someone has actually beaten a couple of campaigns on unutterable and almost all campaigns on pandemonium. Nightmare is piss easy in comparison to that. People cannot imagine how hard a game can get and still be possible. Insurmountable is surely possible aswell. At least the old version. It has not been verified of course, but I managed to beat the 1st chapter of dead air on insurmountable realism solo and almost reached the crane. Then I buffed it because it has to be harder than that to do so lol. His problem was a skill issue and the unwillingness to improve. Calling nightmare impossible is ridiculous.

i'm just revisiting this addon to look at that petty argument we had with that nepnep guy like what, eight years ago? it's funny looking back on it. i never did find out what his problem was

Where it all began...

the og nightmare

The other addon that combines all new difficulty levels is balanced better and behaves more like an actual difficulty level.

I guess it's a bit above my level but I would encourage other people to try it. To me it really is more of a mutational gameplay than a higher difficulty. I get to move tactically and feel every bit of the map, not just the sudden spikes to test my quick reaction.

I enjoy this mod, with it everything becomes a struggle, one wrong move like shooting the wrong car can fail your whole team. It's just so consequential. You'd value every piece of resources you got and be wise about when to use them. The game also becomes more slow-paced because you really got to stay with your team and be at a good spot when the horde came (besides almost everything took "slightly" longer to kill.) It really altered the whole experience, and sometimes the gameplay and balance. If played on an already challenging map it can be unfairly difficult, horde with tank is basically unbeatable for me, endless hordes and some rescue levels are no better, you're gonna eventually make it but only after so many tries and got lucky once.

Not sure if you're still supporting this or if you'd even have any ideas of how to help, but I really love playing nightmare realism except I noticed that panic events (such as endless hordes in cold stream 2 for example) don't work. I'd really appreciate if you had any ideas how I could fix this!

Yes. However I made another addon that makes it not a mutation.

For those who don't find it, it's a mutation ;)

Can anyone explain what's the difference between this and this mod {LINK REMOVED}(https://steamcommunity.com/sharedfiles/filedetails/?id=2100785826)? They both appear to have "Nightmare Mode" but overall, this series of mods (Difficulty levels beyond expert Collection) at least have a description.

Yeah... You need spawn l4d1 survivor addon for average player if you want to survive...

oh nvm found it

I dont see the difficulty, could anyone help me?

yo whats that blood mod in the video

I've never played L4D playing it first time in VR, seems too easy in VR hopefully this makes it hard, last 9hrs getting my VR experience ready so i'll find out tomorrow. Shame i can't jump in VR

is there anyway you can make a mod that gives only the tank incresed health by 2x? or spawn double tanks? that'd be cool if you could, or if thats already a mod, lmk

In case you mean how to access it: Its a mutation. This addon contains normal nightmare and nightmare realism.
In case you meant how to survive the campaign: Basically the same way as on expert just harder. You basically have to choice between playing expert realism until it feels somewhat easy to you or to try nightmare realism really hard.

Does anyone know how to play this on realism? I can't find any tutorial for it.

something really worth trying :)

wait nvm i found it :)

i dont see it as a mutation, could this mod possibly conflict with others?

But the description says 12000.

correction @lizvullok -the tank has now 12000 hp instead of 4000

these mutation sound like fun, adding these as a favorite and can't wait to try em :3

I want to grateful to you for your amazing work . This is a really nice thing

can you make an addon that just makes special infected do more damage

Gay 👇👇

This is COOL. Thank you, author.

Thank you, author. Already did 2 campaigns in realism duo on this difficulty. It becomes really interesting, since you have to pay attention to your teammate

:D

nvm I figured it out. "nightmaredifficulty" if you don't know the command.

Do you know the console command for this mutation?

Thank you for sharing this Mutation, I love it! In public games it usually gets rid of inexperienced players very quickly, especially since I also use the Reverse Friendly-Fire plugin (forums dot AlliedModders dot net slash showthread dot php questionmark t equals 329035) on my dedicated server. Nightmare Difficulty makes the game more challenging and more satisfying when you finish the campaign.

can you add more slot in lobby plz?

Its a mutation.

how do I change to nightmare mode? I can only see Expert

Idk what i put the settings to. But i do not use an addon for the crosshair. I changed it with console commands.

What's the crosshair your using in your game?

It is a mutation. It does not replace any vanilla stuff. So you will not have to enable and disable it over and over.

Hello how to run this mod? I discovered this kind of difficulties . Is this mod replacing Expert?

:)

:o

c :

What aboit the tank? Hunter? Smoker? Or witch?

The charger here has 800 hp (600 is default). The spitter does not have any health increase yet. If you want a 1200 hp charger, you need to play cataclysmic or pandemonium. The spitter never has 600 hp. But with 400 hp on pandemonium, it comes close enough.
