Yes and No. You can make the game "offline" if it's also have offline gamemodes (story, classic, etc).

thanks kiynox for your reply

can we remove or disable items from the apk +obb that depend on server so the game is playable offline i found in Lucky patcher by chelpus function say make it fully offline but i try it but didnt success.

can we use gameguardian to create a script to emulate local server so the server sided game will run offline thinking its the actual server ?!!

yes
• a script to manipulate your android system files that create a server in your phone and listen to it
• an ELF shell get executed when you reboot your phone a script to handle the download and the setup of the shell in your phone
( creation of this kind of scripts is time consuming and not worth the try I won't recommend it )

thank XEKEX  for your reply

so it is preferable to edit the apk+obb than using a gameguardian script.

This is weird. How can you handle the in-game packets then?

In theory, yes, you can. You can setup some proxy capable in intercepting "in-game requests", in meaning that it is understand the datas the game tried to send & receive. Setting this is hard and require in understanding game structs.

You can go this route. APK+OBB is editable using Game Guardian, you can just "DISABLE" in-game server check. It is the common way others create "offline games" but you see:

• - If the games only require "a server" for login purposes, you can still return a fake credential, which altered through in-game files. (Ex: Red Dead Redemption 2, Far Cry, GTA V, etc)
• - If the games only require "a server" for license check, you can just skip by disabling it. (Ex: Minecraft)

You need to understand what this "server" is actually for and the game must have some kind of "Offline Game Modes" (Ex: Classic, Story, Solo Mode, etc) because if it's heavily depends on Multiplayer server, you can't do anything other than stuck at the lobby/menu screen.
