If the Dark Souls series managed to seduce players and journalists, it was mainly by word of mouth. It was such a great success that Dark Souls 2 was named "Game of the Year" 2014 by the vast majority of gaming magazines and websites. To date, this saga is one of the most important in the gaming industry. The odd thing is that these games are well known for their difficulty and their cryptic universe. This publication narrates the epic success story, but also describes its gameplay mechanics and its specific lore across more than 300 pages. Characters, plots and the scenario of the three Souls (Demon's Souls, Dark Souls and Dark Souls II) are deciphered by Damien Mecheri and Sylvain Romieu, who spent a long year studying these dense and enigmatic games down to the smallest detail.
