You truly hit all the right marks with this. It's futuristic (high tech), spacial and airy (ship) with the mood jumping between menacing and sinister with that one low sweeping sound and playful and energetic with the driving bips and the higher pitch aah (sneaking around on). I haven't played the game (although I'm thinking that's because it's not out yet) but given your description of the context, this track is positively perfect.
