I know why there’s a bug related to the HUD not being centered in the version v1.21! I I found that bug reoccurring in GZDoom 4.6 and 4.5.

The line 55 of the file “SBARINFO” in the Mayhem Mansion PK3 is the one causing that problem. Replace that…

drawimage "STBAR", -134, 164;

… with this.

drawimage "STBAR", 0, 164;

I used Slade to find and edit the file.

thank you for 1.13! however there is some question in lvl 6 remake.


- can you still pick up golden skulls? 

- the secret (where you find cherry bomb),there is a light on wall on it,but it doesn't seems to be open as i remember.

(1 edit)

did you pick up the phone and then talk to the NPC who requests the golden skulls? it works for me.

crap,i don't see nor hearing phone ringing.

map 3, elevator won't drop its shroud?

i don't get it,maybe you should get a screenshot

maybe because i'm playing this on easy mode, but this giant silver guy won't spawn in this room for some reason, and it seems like killing him is the trigger for the elevator.

noted, gonna release a new version around halloween with a buncha fixes.

good day,i would like to report a bug,not really alot in lvl 4 and lvl 5 so here goes. 

lvl 4

-when you pick all 4 ingredients,the passage doesn't open up

-the johnny tank secret doesn't count as a secret


lvl 5

when you kill final boss,the teleport exit doesn't open up


that's all,i hope that is useful! :)

"-when you pick all 4 ingredients,the passage doesn't open up"

theres 5 ingredients to get before it opens.

EDIT: WAIT, i figured out the problem, yeah it requires a zeta emblem too for some reason, ill have to fix that. (just put "give zetaa" in console for now)

"when you kill final boss,the teleport exit doesn't open up"

ffffffffuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

lemme fix it... =_=

don't forget about johnny tank secret doesn't count as secret :) 

fun fact: in 1.1 ver lvl 3, i don't get stuck in bombs room,i don't know how.

level 2, stuck at 7 keys.... hint?

you will pick up the map that should tell keys

I figured it out: in the blue room with the green elevator floor, you can trigger the floor to not go down all the way, and if you missed the switch to open up the road, you won't be able to progress.

Few extra problems spotted in level 6, one of which can break the level, 1.12 coming at some point lol.

How to leave the bombs room (First time you see them as a weapon) on level 3? I kick prisoner's butt with my melee, he vanishes, but then nothing happens. Stone pillar won't move. I just lick this room in and out seeking a solution, throwing bombs at pillar/hint box/ribbon, pressing "Use" on every centimetre of the walls, yet it is absolutely futile. I've been stumbling upon this problem for almost four years of playing MM, I think it's time to solve it (Well, maybe it's just me being stupid as hell). Here's the screen of that room
I'm using latest GZDOOM version

Yeeeeeeep that's a bug that's been haunting this level for years and I forgot to check up on this bug for 1.1, especially since I never had run into it myself. I'll try having it fixed in the next version. x_x

Thanks! Can you please tell me where can I find the last ingidient (It looks like some kind of gray can) for potion on level 4? Searched with noclip/editor, still can't find it

Plus. I've found a few more bugs, I'll report them here, if you'll ever wish to fix them
- Level 3, invisible line. Line is somehow connected to the elevator, so it probabbly messes the line up


- Level 3, warp door closes after player enters sand man's chamber, though it can not sometimes, because TV man that appears behind it can block it


- Level 4, at this place there is no line block for bridge at both sides. This way I was able to walk on lava freely, it didn't kill me


- Also there is a way to jump really high using the "Ice anvil" spell, same as rocket jump. It is very fun tough o_o

(1 edit)

All those been fixed, dunno what i can do about the anvil though, i know how to remove the ability to "anvil jump" but it makes the anvil not hurt you at all, which is something i don't want. so i dunno what to do. 

Edit: Also, that last ingredient is in the volcano, should be unlocked after you got everything else.

How can I play v1.1 with GZDOOM? Zdoom is unholy, scales everything up like crazy

you have to load both MayhemM_EE_v1.1 and MM_Levels into it

Thanks!

you're welcome,took me about 10 mins to think about this

Is the game finished and needs no more updates?

theres gonna be an update (1.1) sometime down the line
