Forgive me, but how do you play a truck driving game in co-op?
Because the missions are things like deliver 7 or 8 different sets of cargo from A to B, across tough terrain where you may get stuck (at which point the other player can come and use a winch or crane to get you out of being stuck in mud/snow/rivers etc) , plus there are missions to build things or take oversized cargo like enormous pieces of machinery etc and in those instances it can help to form a convoy so that you can carry more etc. Although the game involves truck driving, its not really a truck driving game, its more like a freight moving company game , so multiple drivers in convoys, using different types of vehicle helps a lot. For example, one player can drive a truck with a fuel tanker on it, so that you can refuel on long trips, or they can come as a repair truck to repair the other players when they get damage and so on.
