Bloons TD 6 is a unity game.
NOTE: This is talking about the APK of the android version of the game.
Link (File is too big): https://drive.google.com/open?id=1cCvff ... B7ACDDqX7a
This is the archive which contains the dlls. ^

Usually, the dlls are in the folder like this: APK/assets/bin/Data/Managed/dll.dll

But the new Unity 2018 has made it so these dll's are no longer out in the open. Instead, I found them to be here in this Game.bin archive. I have worked a lot with unity games, and a majority of the scripts get compiled into a dll called "Assembly Csharp.dll", unless the developer has their own.

If you open game.bin in a hex editor, you will see
1. Some sort of header
2. FAssembly-CSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null

This matches the format of a dll, having the version and all.

I just don't know how to extract them from this kind of archive. I can't confirm this, but it might be this way in all Unity 2018 compiled games.

I used a different program, and managed to slip a list of dlls with references in the game.
NOTE: Some of them aren't actually needed, and are just here because there is a reference to them. Other unity games have references to ones like "UnityEngine.HoloLens" but don't actually need them to run. If you don't find a few of them in the bin, this is why. A lot of them are also just there because they are a part of unity. For example: UnityEngine.Analytics

Facebook.Settings.dll
UnityEngine.Timeline.dll
UnityEngine.UI.dll
Facebook.Unity.dll
UnityEngine.Networking.dll
UnityEngine.TestRunner.dll
UnityEngine.HoloLens.dll
Stores.dll
UnityEngine.GoogleAudioSpatializer.dll
UnityStore.dll
Ninjakiwi.LiNK.dll
UnityEngine.Analytics.dll
Assembly-CSharp.dll
Assembly-CSharp-firstpass.dll
Editor.dll
UnityEngine.Advertisements.dll
UnityEngine.SpatialTracking.dll

Please let me know if you need anymore information.
I hope we can break this...especially if all unity games will be like that

I read all of this note's...
Can you upload this .bin file in [b]mediafire uploader[\b]?

And an other thing... It's posible to inject or add a new dll to a Unity game (a compiled game)?

update: i've resolved this by realizing this is just some weird unity 2018 thing, but the real deal is in globalgamemanagers.assets

This is a big bump but I've started ripping apart this apk and I'm very stumped on how to properly extract the DLLs out of that assets file.
on top of that, I can only find a list of references to assets but not actual assets.

Maybe some more info on this would be helpful. I Haven't really found much on this at all.

I'm mostly interested in scripts.


update: so it turns out there is no csharp assemblies. I mean there could still be but it looks like the game uses il2cpp. Meaning all the C# code gets translated to Cpp at compile.

Unless there is a version that doesn't use il2cpp we won't get good code assets from the game at all.

I'm not sure that's true. Looking at the the game.bin file that data is pretty structured and might just be a form of compression. Organizing it a bit will look like this, not entirely sure what's in it entirely but I would lean toward thinking the dll is in fact in that file.

Code:
