A DRM-free version of Sylvio is now available on the Humble Store by way of the official website for this first-person horror game for Windows and OS X after previously only being offered on Steam. This trailer shows off gameplay and there is also a playable demo for a hands-on sample. Here's word on the game, and its firm roots in not science: "Sylvio is about a ghost recorder called Juliette Waters, who finds herself trapped in an old family park destroyed by a landslide in 1971. She uses her skills in EVP (Electronic Voice Phenomena) to find voices of deceased in the radio static, and slowly learns the horrific story of the surroundings. Solve environment puzzles, have séances, disturb black orbs, and explore a park left to its demise."
