Dark Fall: Lost Souls is a 2009 first-person psychological horror/adventure game developed by British studio Darkling Room and published by Iceberg Interactive for Microsoft Windows. It was first released for download via Steam and Darkling Room's official website in November 2009. It was subsequently released for retail in Europe in January 2010 and in North America in April. Lost Souls is the third game in the Dark Fall series following Dark Fall (2002) and Dark Fall II: Lights Out (2004). It tells a story relatively unrelated to either although it is set in the same location and features several of the supporting characters from the first game.
