Based on the Song of Blades engine and written by Andrea Sfiligoi, Swatters lets players create sci-fi battles between humans and alien bugs from books, movies or their own imagination. Each player or team pits their human or alien forces against their opponent using miniatures and a tabletop area to create a battlefield. The game includes rules for adapting several popular tropes (power armor, xenomorph aliens, alien arachnids, interstellar marines, etc.) and has several scenarios to play through. Currently sold as a 45 page full-color PDF download from the publisher. The game is based on the Song of Blades miniature wargame engine that's been used for everything from fantasy to ancients to Napoleonic warfare.
