Dark Void

"The game's story casts as you as a fairly unlucky guy who's sucked into an alien vortex and winds up in the void, Bermuda Triangle style. It turns out you're not the first human to get nabbed by the aliens, called Watchers, and there's a small contingent of humans surviving within this mysterious space. The action revolves around you exploring your new surroundings and trying to find a way out. "
