There aren't any "specific" hacks if you would call. They're are scripts that you can execute using a string or certificated DLL used for executing scripts. If your wanting to "hack" Arma3Life specifically CC Life or some shit like that. Find the strings that aren't in the BE Filter from his mission file. You can find the mission file from here: C:\Users\(REPLACE THIS TO YOUR COMPUTER PROFILES CURRENT USERNAME)\AppData\Local\Arma 3\MPMissionsCache or %appdata% then go to local, Arma 3 and MPMissionsCache. Open those pbo's with pbomanager and you're done.
Good luck.
