Gatling Goat Studios' Traverser stars Valerie Bennett, the traverser with the ability to swap between the mirrored Uppertown and Lowertown, the two sides of an underground city connected together by gravity plates.
The city, called Corporation, has an economy based on air. The lower-class, closer to the core, refine oxygen for the upper-class who sit above them, away from the noxious core and crime-laden city.
You'll be tasked with sneaking around guards, solving puzzles with your gravity glove along the way. The above trailer is all cinematic, but there are some in-game screenshots in the gallery.
Traverser is slated to come out Q3 2014. I'm definitely keeping an eye out for it.
