I think the "Press [SPACE] to continue" is hard-coded.

Problem: I finally decided to use my Xbox 360 controller, and there should be no binds to the keyboard, but it still asks to press space to continue. Example: After ground scanning

Solution: None known. There seems to be no bind to the space key in Settings.ini for Player 1


It's only a minor inconvenience, but something to keep in mind for next release
