Rockn Roll, I meant followers as companions, other characters who help you during your traveles in the ruins of the planet.
King of the Wastes, I'm just talking about playable in game characters that travel with you and fight along side you.
Uhm...as King of the Wastes pointed out...RAGE is a multiplayer game. Although there will be Non-Playable Characters (NPCs) which give you quests or sell you stuff, so far the indication is that there will not be any of them which assist you in fighting or whatever...because that is left to the other players in the game. If you want followers then you can have them by making friends in the game, or if your existing friends get the game and join the server you are playing on.
With RAGE coming so close to completion it's starting to get very frustrating that there is a lack of support on the forums by gamesas or idSoftware or information in the news about the details of RAGE that can answer these kinds of questions. Compared to the details released for other games, RAGE gets a score of 2 on a scale of 1 being the worst and 10 being the best.
