lan/hamachi multiplayer?

well i have nearly finished a game and i want to know how to make lan/hamachi multiplayer, like just a simple script or something that will make it so that it can be played over lan.
it is a 2 player game and each player has different controls so all i would need is a script or tutorial or something that will let another person interact with the game, and then ill put a thing at the top of the screen saying “dont press the other players controls or chuck norris will roundhouse kick you in the face”

lan or not your asking how to network, i suggest you start with looking at unity’s networking tutorials, what you want to do is a lot harder than you might be thinking
