A big problem appear : this game is protected by BattleEye : the anti-cheat who check process activities on your pc... So a cheat for battleEyed server maybe really hard cause need to block the anticheat verification system... On non-battleEyed server you can cheat but it's only on non official server. So you can creat your own server, host it from your gaming pc or from another simply pc just like a server, open yours router's ports if you wanna play with friends and use the "cheatadmin" command list ^^
or if you want ESP and Aimbot, pass your server to non battleeye with the following command at the end of the .bat file that you creat to launch your server "-no battleeye". i know that WallHax have a cheat for non battleeye servers but it's not free ^^
