Resxt i don't know how to start a server, i'm new to this. What i did until now was playing in Lan mode and hitting "xstartpartyhost" in the console to get into a match with bots

Resxt I'm guessing since it's Lan, it will work offline. Can you tell me how or direct me to a tutorial guide?

Can i host a Lan server to play on my own with bots while xp progression is still a thing for everything?
I want to play the game completely offline without the need of the internet.
