@Mr.Midian-P sorry for my late reply, and thanks for the instructions. I'll give it a try asap and see how it goes. Thanks! :D

@Alex_Co All the models are located in assets\packed_data\actor when extracting the APK file using Bandizip or something. (Remember, the APK must not be cloned using an APK extractor and must be downloaded from their website or found elsewhere. You'll notice if the APK is less than 1.88 GB)

while the other files are located in com.vng.sea.metalslug\files\source\packed_data, which you compress it using the EX File manager in bluestacks. which can be found in the Internal Storage and Android Data folder which is named "com.vng.sea.metalslug" and extract it using Media Manager.

@Alex_Co go to the Debug settings and turn off "Show Error Message" due to the newer versions.
i recommend using a modified version of AssetStudioGUI by RazTools.

@Mr.Midian-P then I must be doing something wrong, because I used the same approach with the official APK file (AssetStudioGUI + SEA version), but when I try to load the files found inside the game after unzipping, I tend to get errors about AssetStudioGUI being unable to load some (or, in a few instances, all) of them. And what I manage to load consists mostly of basic primitives.

@Alex_Co i use AssetStudioGUI to extract the models and open them up in Blender. for the bones I don't know how to extract. also some parts are separate, which you can easily assemble in Blender. Also, each file are separate. One can be found on the original APK file, which can be downloaded on their Website and can be extracted using something like Bandizip. The other can be found in the cache folder of the game which is located on your phone's or Bluestacks android folder. of course, you need to have EX File Manager installed in your Bluestacks to compress the folder into a Zip.file and then export it using Media Manager.

When I said you need to download the APK on their official site... an APK extractor App doesn't work. you must download the APK here:
https://hjdt.qq.com/ (CN Version)
https://metalslugawk.vnggames.com/sgmy/ (SEA Version)
https://msawk.haoplay.com/ (Global Version)

Of course the CN and SEA version contains more stuff however you need a Wechat account for CN but you can still extract the Android APK.

@Mr.Midian-P how are you extracting all these models from the game? I tried it myself, but to no avail!

What Is this game!? Is a shooting game from the y96 (pixel game see in the sprite resource)

@LegoLoco7 you never heard of Metal Slug? O_o
It's a power up transformation, you become a bigger slower target, but your bullets and other ammo also gets bigger and does more damage in general.
