Dump for Standoff 2 game Repository have 2 dump folders. The first is a dump with deobfuscated methods, and the second is a dump of the newest version.
You can use dump for their mods.
Standoff 2 anticheat have Lib, Apk, Obb, Sign check. You can return original hash and sign with offsets in secret class. But.. you need to return SafeString.. This will be a huge problem. Standoff 2 detect smali and manifest changes, I do not recommend making the menu with floating window permission.
