@JohnDon8 There are 2 things you can do:
Either:
Host a dedicated server running your mod
Server setup: https://forum.plutonium.pw/topic/13/plutot6-server-set-up-guide
Loading gsc on dedis: https://forum.plutonium.pw/topic/10/tutorial-loading-custom-gsc-scripts
Or:
Find an injector that works with pluto and inject into plutonium-bootstrapper-win32 but be aware:
Switch to lan mode in the launcher before doing this (arrow next to the play button) or you will be banned by the anticheat!
