Help me, I don’t know how to download maps.
You have to download it off of someone’s fileshare or use the search ingame to find them. If there’s still a way using waypoint, I don’t know how, sorry.
Assuming that you’re taking about custom maps, just go to the custom map lobby/menu and select maps. Once on the screen, just go down to fileshare and either search a map name, or the name of the person who made it.
