Fortnite's version of the mode popularised by PUBG, for all their similarities, doesn't actually support duos or squads (squads was added at launch) - though these are planned for later when the player base grows to a point where it makes sense.The existence of this mode has made PUBG developer Bluehole uncomfortable, to the point that the studio issued a statement saying it's not happy, and is contemplating further action.In a followup interview, Bluehole explained that it doesn't have an issue with Fortnite copying PUBG necessarily, just that the game's developer Epic is a partner of Bluehole's.
