In the second tutorial mission, the player is given the opportunity to dock to a capital vessel within the training zone. The mission specifically informs the player that the docking zone is a bright white opening "on the bottom of the vessel"

...but there is no "up"/horizon indicator present in the game.

Nicronon over on youtube was having this exact issue at around the 19:08 mark, which brought it to my attention. He was flipped but with no obvious indicator he hunted around the ship for a bit before moving on (though in editing had come to the right conclusion)

I'm not sure the best way you'd want to provide a fix - a hud marker that can point at the docking port, an in-space marker for the training sector ship exclusively, just changing how its referenced in the mission, or... anything? I just remember this question coming up a few times before, though it'd been a bit, but then seeing Nicronon having this issue directly gave me an "aha", and figured I should share here.

I think that tutorial is deprecated.

The new tutorials are in usage on some input families, and not others, because not all the input-handling has been implemented cleanly for referencing controls the same way.

Anyway, thanks. I'll take a look, on the next new-user-experience pass.
