You won’t quite be able to figure out what’s going on in this trailer for new horror/FPS Betrayer. But it’ll still make you feel queasy.

Maybe it’s the ghosts flying at the camera in a stark, 17th-Century rural landscape. Or the muskets, crossbows and tomahawks promised on the game’s official site. But Betrayer—which PC Gamer says is the work of developers from the teams that made No One Lives Forever and F.E.A.R.— looks like it’s worth paying attention to. The PC release is due out on Steam on August 14th. The official description follows:

Betrayer is a first person action adventure game that takes you to the New World at the turn of the 17th century.

The year is 1604. You sailed from England expecting to join a struggling colony on the coast of Virginia. Instead, you find only ghosts and mysteries. What catastrophe blighted the land and drained it of color and life? Where are the settlers and tribes who lived here? And who is the strange, silent woman in red who aids you from afar?

Clue by clue, you must piece together the story of what befell this doomed settlement and find a way to set things right. You will be hunted by corrupted Conquistadors and ravening shadows as you explore an expansive wilderness in order to trace the brief, tragic history of the colony and search for survivors.
