If so, this would limit who gets to play the game and how. You can’t have two main characters, unless the game is built from the ground up as a cooperative experience.The game has to retain something of its turn-based roots. VATS, which was introduced in Fallout 3, would be difficult to implement in a cooperative multiplayer environment.Making it mandatory for the player to cooperate with others would take away from completionists’ achievements. All of the game’s quests should be completable alone.Fallout has been a traditionally solitary experience, following the exploits of a single main character (the Vault Dweller, the Chosen One, the Lone Wanderer, the Courier) as he or she travels throughout the wasteland.
