The game's called plundernauts. It's an IOS game and is pretty much abandonware since the devs behind the game shut down a few years ago

The game's cracked and I'm currently trying to mess around with the code in Assembly-CSharp.dll to figure out a way to make the game work offline
but I can't seem to be able to find any methods

The game was made using Unity 4 and is 32 bit, so IL2CPP couldn't have been used since IL2CPP can only applied to 64-bit games


Did the devs apply an obfuscation method to Assembly-CSharp.dll directly? Or is this a limitation of DnSpy and other applications like it?

Mr.Pringlez
il2cpp most definitely can apply to 32 bit games. what you're looking at is a mono game, and yes, devs can apply obfuscation to the assembly directly.

Mind sending the .ipa?

Really? I've come across a few blogs from unity's site while researching obfuscation methods, which stated IL2CPP was a feature that was available starting with IOS 64-bit devices, which is why I assumed this game doesn't use it

There isn't any lib folder. The .ipa was extracted using Clutch and hasn't been modified, so no IL2CPPDumper was used or anything of the sorts

here's the dll under the 'Managed' directory. I have the download to the .ipa linked in my previous replies if you want to mess around with the files yourself

It is possible those things store in asset bundle, might be worth looking

I'm honestly stumped. I think the game might be using AOT compilation, but the feature wasn't introduced by unity until 2017. Anyone have any idea what could be hiding the methods?

You can use DevX to mod this game, lots of things show.

Check my thread on DevX for the download + some guides on how to use it.

Oh word. Thanks for the reply man. I remember trying to get a crack of devx to work a while ago, but it never worked for me. I'll give it another try

By the way did you see anything about connectivity in the code? I'd totally understand if you didn't look too deep into it tho

I havent looked into it, just wanted to quickly show you that you can use DevX to view/edit the Monobehaviors and etc of the bundles inside the ipa. I'll leave the exploring to you, good luck!

btw btw, could you explain to me real quick why I can't see the statements under the functions? Is it just something that can't be retrieved in de-compilation for IOS games?
