It seems when you play multiplayer, you can choose any ship you want in the lobby. I suspect the single player experience to be more like RPG style in which you choose a ship at the beginning and then you grow your hangar of ships with experience gained.
But will there be a crossover between these two worlds? Like will there be some deathmatch mode in which you are only allowed to use the ships you got in single player? Or are they complete different things?
