This is a guide that explains how to confront other players in the game.
To confront a player, you will have to post at a location, maybe agree about where to meet. You then post by turn.
It is possible to trade, and by trading, there is no weight limit.
It is possible to raid. To do this, you can threaten or even kill other players.
To kill another survivor, you use as much ammo as by killing a cow. Look here.
You can talk about how much you want to raid, trade, etc. This is up to you.
