A font chosen (and approved) by the aliens themselves is the best option for futuristic designs. Indeed, would you doubt their expertise?
Baregx is everything quality futuristic typography can boast: it's a monolinear sans serif with a non-conventional glyphs appearance (probably elaborated by Predator or ALF(unlikely)). And it's even more, as the standard set of characters is complemented by multilingual support, numbers, and punctuation. You can use Baregx for any project, of course, but the best use will be a logo on the board of your spaceship or a branding design for a sci-fi movie.
