The 13 Sentinels: Aegis Rim Prologue prologue game launched in Japan on Thursday. Players can acquire the game through four different releases, including bundled through newly-priced re-releases of previous Vanillaware games Dragon's Crown Pro and Odin Sphere: Leifthrasir. 13 Sentinels: Aegis Rim Prologue contains the main game's first three hours, and save data for the demo will not be transferable to the main game.
