It's a while since I have run a game set on a submarine, but as I sit here with Track #1: On Patrol playing over my speakers (to the bemusement of my family!) I think it will fit in very well for any game involving space travel too.... just burbling away in the background when out in the black.
Really nice atmospheric soundscapes to set the scene without intruding on it.
Recommended if you have suitable situations in your game.
