Been a while since I played so I suppose things could have changed but I doubt it. You can definitely play it by yourself and likely have a good time but every where you go and everything you do will have that feeling of “designed to be played with multiple people” all over it if that makes sense. The only big downside is you have pretty much no chance against other teams just trying to make things difficult for you. Also piloting a ship is a bit of a pain but yourself but you can just use smaller ships to make it easier.
