Miasmata

Miasmata is a first-person survival adventure game, independently developed by brothers Joe and Bob Johnson. You play as Robert Hughes, a plague-stricken scientist on a journey to discover a cure. Your adventure begins on the shores of a remote island called Eden. Long ago, Eden was inhabited by a group of indigenous people, whose extant monuments still decorate the island landscape. Eden is now home to a scientific research outpost, and it is your hope to reunite with your colleagues working there. Unfortunately, you'll soon discover that something has gone terribly wrong.
