Ah, the working week hasn’t begun until we’ve posted a dreadfully sinister indie game. Courtesy of the Indie Games blog, Activate the Three Artefacts and then Leave has you navigating an ominous, claustrophobic environment using your mouse, the WASD keys and by listening out for sounds, though that description doesn’t convey the game’s nightmarish atmosphere. It plays a bit like the hallucination of a sedated hospital patient who’s been left staring at white ceiling tiles. Videogames! Go play.
