It turns out the game is the real deal, though, and Atlus went ahead and launched the free PC game as Shin Megami Tensei: Synchronicity Prologue.
At first it seemed like little more than a goof when Atlus promoted Shin Megami Tensei: Strange Journey Redux with a trailer for a 2D platformer featuring Jack Frost and Jack O’Lantern.
Den-fami Nico Game Magazine’s Ladybug team—who previously developed the bonus game featured on the first KonoSuba Blu-ray—handled development on Synchronicity Prologue.
