OP custom weapons mod?
Is there a mod which removes the power meter in the weapon factory?
I want to create really OP weapons, since I never play this game online anyway.

To download XomView visit this thread here: Worms4Mayhem - Worms Ultimate Mayhem XomView Thread [worms4mayhem.forumotion.com]

I don't think it works in multiplayer, but I haven't tested it yet.

Then you have to basically do is what the guy in the quote had said, find your save file and search for your custom weapon's name (I think). Then once you've done that you can change its value to something higher than what it was before. But there might be some crashes and stuff in your game because of the CRC check.

Here's someone's quote about it in the thread I have linked above ^^^:

- Skip the CRC check, by overwriting the JNZ command directly, save the modifications as a new file or edit it directly as binary.
- Write a tool that recalculates CRC. That's what I did before. Later I decided to use method 1.

This allows you to change the most values. Script.xom has it's own CRC I believe.


I don't know where that exact save file is at though precisely. So I'm going to do my research later on and see where I can find the save file. Stay tuned and please reply to this comment even though I just necroed this and everyone is gonna see this thread that was once dead now revived.

But this'll answer your discussion thread from 2.5 years ago. Hopefully if you're online you'll be able to see this.

Note that the version of xomview in the mediafire link is very old, and doesn't work 100% with Worms Ultimate Mayhem. You can get the latest version by searching in w4tweaks: http://worms.pro/search/?q=xomview

Update: I found and modified the values of a custom weapon and set some of the values to 254, but it seems like the game does some checks on the savefile.xom before actually using the values. So unless someone creates a mod that disables these checks, we're not getting OP weapons this way.

You could still use the wormpot though:
Specifically select OP modifiers in the wormpot using the arrows in the casino machine. You could use "Double Damage, "Super Hand To Hand, etc. There's plenty to choose from, so take your pick ;)

If you're playing remote multiplayer, there's a mod that let's you use wormpot in multiplayer in moddb: https://www.moddb.com/mods/mmp/addons/mmp-multiplayer-wormpot-mod-v10

Update 2: If you really want to just give yourself the advantage, you'd have to get Worms 4 Mayhem. Nowadays you can get the CD from archive.org, because Team17 decided to publish it themselves.

# Transfering your Worms Ultimate Mayhem progress into Worms 4 Mayhem
You could try to transform your SaveGame.xom ("C:\Program Files (x86)\Steam\userdata\1051434104\70600\remote\SaveGame.xom") into an xml using AlexBond2's Xom2Xml: https://github.com/AlexBond2/Xom2Xml. The replace the worms 4 mayhem savefile with your generated one. I think that should work, haven't tested it myself though. Make copies of the savefiles before trying anything, just in case.

Aw, that's a shame. Although it makes sense, since that'd give competitive players an advantage.

That's usually what I do when I want to cause chaos, yeah. It gets really crazy when paired with tiny randomised maps, since that can blow up like 90% of the worms at once.

ah, I don't actually play online multiplayer at all.
It's probably really weird, but I play local multiplayer and then play all teams by myself. It's odd, but it's also fun.

huh, I can't seem to find anything officially uploaded for Worms 4 Mayhem on archive.org.
The top results all are uploaded by third parties if I understand correctly
