There is, it is still not great but it is better than nothing. After you create your character and select your starting planet a window pops up recommending people play the tutorial if they are new. If you hit ‘skip’ then it dumps you into the game with minimal tooltips.There was a tutorial?? When I started the game I was in a room that I couldn't get out of. If that was the tutorial then it sucks otherwise I didn't see it, lol.
In the future while you are on foot you interact with things by holding ‘F’ which lets your move the mouse and interact with things like door buttons, elevator buttons, etc.
