Atlus recently showed off a side-scroller game featuring Jack Frost and Jack-o’-Lantern as a made-up game, but it’s been revealed as Shin Megami Tensei: Synchronicity Prologue, and it is available now for free.

Shin Megami Tensei: Synchronicity Prologue was made by ledybug, the development team by Krobon, who is known to be an avid fan of the Shin Megami Tensei series.

Atlus says to not think of the game as something directly related to Shin Megami Tensei: Strange Journey Redux, but rather, something that tells us what was going on in the background during the U.N. Schwarzwelt Investigational Team’s activities.

The game is available to download here, and will be up for grabs until December 24, 2017. You can get a closer look at the game in our previous report.
