Pierre Maugein, under the pen name Killy, wrote for Jeuxvideo.com from 2003 until 2006. Although he trained to be a graphic designer, he decided to move to video game journalism because of his love for the industry. He worked as a freelance contributor for JeuxActu and then wrote for the Ragemag website on various topics, from art and literature to science, cinema and video games. Since then, he has been on the staff of Journal du Gamer. He has also contributed articles for Level Up, published by Third Éditions.
