i have a issue with the spitter spawn which doesnt spawn anything and i can just run for the chapter like nothing even if i stand still no spitter spawns and i proved it in No Mercy and even in Dark Carnival and i want to play with a friend but this issue leaves the campaigns as super lonely beta map

Stupidly frustrating yet super fun and enjoyable. Great mutation!

Also, I'm 100% sure it's impossible on Hard Rain lmfao. Chapter 2 elevator crescendo is brutal.

Let me know when you post them. I'll definitely take a look. If nothing else, the mutation's pretty good for magnum practice since that sucker is meta for Expert. It'll be fun to see you show off on that front.
Niels_L 19 Oct, 2018 @ 5:26pm 
Thanks for your response :) The issues are not gamebreaking luckily so it's not something to get sleepless nights from haha
I do hope that sometime you get to create a fix, if not with someone else. It'd be pretty cool to get to do The Sacrifice in its entirety or do Dead Air map4 legit q:
But either way, I'm not complaining. Thanks once more, and the video's sure are coming :) No Mercy took me hours to beat so mostly looking forward to putting that one out.

@Niels_L Hey there! Glad you enjoyed my little mutation. I’m not surprised there are some problems with it, mainly with scripted events like Tanks and hordes, but I can only chalk that up to my limited experience with coding mutations. I haven’t worked on any such endeavor in years so I’m rusty as all hell. There’s probably a fix, but I’d have to bust out my tools again and relearn it to make that happen. It’s simply not designed with scripted events in mind. I’m annoyed by it but can’t promise a fix anytime soon. That said, you deserve a medal for surviving all the campaigns on this mutation solo. I’d love to see a video of that one.

Either way, thanks for the feedback and I’m glad you enjoyed it!

Completed all campaigns on solo expert without restarts :) Really fun mutation, even more so with friends.

Though there are a few bugs which have been described in the comments here already, but I still would like to summarize them:
- commons still spawn on the following maps during events:
* Blood Harvest, map 3 & 4 [c12m3_bridge & c12m4_barn]
* Cold Stream, map 1 [c13m1_alpinecreek]
* Dead Air, map 4 [c11m4_terminal]

The gate event on Dead Air map 4 is by far the worst one due to the amount of commons, making it extremely difficult to complete even on Easy.

Lastly, The Sacrifice seems to be impossible to complete due to the tank you need to kill in the first map to continue. Upon trying to open the second train cart door a message will display telling you to exterminate the tank first, but due to it not spawning this is impossible to do so.

But other than that, like I said, fun mutation which is definitely up there in my list of favorites.
Anduron_Lazul 20 Jul, 2018 @ 12:44pm 
Same thing again:
Train car event in 3rd level of Blood Harvest,
railway bridge leading to saferoom in 4th level of Blood Harvest,
bunker door in 1st level of Cold Stream
Anduron_Lazul 20 Jul, 2018 @ 12:12pm 
Found a glitch. In the 3rd level of Dead Air, when you activate the van or go through the metal detector,

The hordes of Commons will still spawn, defying the entire point of this mutation and making it impossible to complete.

too easy just need to dash trought the map but its easy same shit as expert. need some update to make more spitters and a bit of zombies
XiaoXiaoMan  [author] 18 Sep, 2016 @ 11:09am 
No problem. Have fun!
Renmei 18 Sep, 2016 @ 10:55am 
Nevermind, I've figured it out already. But thanks anyway!
XiaoXiaoMan  [author] 18 Sep, 2016 @ 10:54am 
The mutation can be found under the Mutations menu, under four players. It can only be played as long as all players have the mutation installed, and you have to be playing it in a local server (since there are no dedicated servers runnnig the mutation).
Renmei 18 Sep, 2016 @ 2:26am 
nnnhhh how can i play this?
"map [map name] The_Floor_Is_Lava"? Or what? I can't play that even if i would like to Play With Friends but no one except me would be in that server.

I finally got around to fixing my mutations to work with L4D2's new EMS. Both mutations should now work properly and shouldn't conflict with each other.

It's supposed to show up as "The Floor Is Lava". Why it doesn't do that is beyond me.
The Probl-o-matic 3000 11 Mar, 2014 @ 11:41am 
in the mutations menu it shows up as testmutation2, similar to how you worded it in the console :boomer:
Say Vandelay 10 Mar, 2014 @ 5:28pm 
Alright, just after I posted that, I switched it to Local Server and it worked. Thanks.
XiaoXiaoMan  [author] 10 Mar, 2014 @ 5:26pm 
Chances are you need to make it a local server, since there are no official or community dedicated servers for this mutation.
Say Vandelay 10 Mar, 2014 @ 5:23pm 
Huh... I loaded up the mutation using the "map MAPNAME testmutation2" command you mentioned earlier, but I can't seem to start it up normally. When I click "Start the Game" in the lobby, it searches for a server and the icon spins, but it doesn't find a server. It just keeps going like that.

Have you encountered any problem like this?
XiaoXiaoMan  [author] 31 Jan, 2014 @ 1:18pm 
I did, actually. It should show up as "The Floor Is Lava." It does on my copy, not sure why it doesn't work for everyone else. That's something I'd have to look into.
The Probl-o-matic 3000 31 Jan, 2014 @ 12:50pm 
ah i see, also i looked at the menu and saw there was a mutation called testmutation2, tried it and enjoyed playing the mutation. However is there any way you could change the ingame name for convenience reasons?
XiaoXiaoMan  [author] 31 Jan, 2014 @ 11:08am 
You may need to restart L4D2. To ensure it works, open the developer console and type in "map MAPNAME testmutation2". If it doesn't work, you did something wrong or it's conflicting with another plugin. The console will also tell you whether any addons are conflicting.
The Probl-o-matic 3000 31 Jan, 2014 @ 7:58am 
how do you play this, i subbed but it doesn't show up in my mutations list

XiaoXiaoMan  [author] 22 Jan, 2014 @ 12:35pm 
I'd have to look, but I don't think my mutation really takes that much space. Still, I understand, essentials only is a good mentality when you're tight on space.
c 21 Jan, 2014 @ 11:10pm 
sorry, not downloading beacause my pc has holy 30 gb ;_;.
XiaoXiaoMan  [author] 21 Jan, 2014 @ 9:03pm 
I'm not gonna lie, I only really designed this with vanilla L4D2 in mind. It can and probably will conflict with other add-ons, namely mutation addons. But custom maps... I don't know; I haven't tried.
c 21 Jan, 2014 @ 5:14pm 
this does not work in other maps? (like Tank Challenge)
Grey 13 Dec, 2013 @ 9:38pm 
so as i ::D

Actually the human bots don't bother me, it's the spitter bots, they rarely go after the human bots
DoctorHandy 20 Jul, 2013 @ 7:00pm 
cool:tradingcard:
Con 20 Jul, 2013 @ 10:19am 
Thanks yeah it's fine the mutation works great! Amazing fun btw!!! Good job :tank:
XiaoXiaoMan  [author] 20 Jul, 2013 @ 10:13am 
That's the one, yes. I don't know why it's doing that for you.
Con 20 Jul, 2013 @ 9:44am 
Is named 'Testmutation2' under the four players option? I can't see it in there otherwise :)
XiaoXiaoMan  [author] 19 Jul, 2013 @ 10:29am 
Not much I can do about bot stupidity. This mutation is best played with humans.
Jesteruk 19 Jul, 2013 @ 7:01am 
Atleast make a spawn timer or an acid recharge timer, I play on my own with bots and all eight spitters chase me only, I can't even start a crescendo without dying, unless somehow bots the spitters
Kiowa 8 Jul, 2013 @ 11:03am 
oh lawd.
XiaoXiaoMan  [author] 4 Jul, 2013 @ 11:40am 
That'd be the one. I don't know why it's showing up like that though.
