It's no secret that once something is online, it's typically impossible to stop. Fighting is Magic may have gotten the axe from Hasbro back in the day, but various fans have kept the project alive over the years with mods and spinoffs of the original. Apparently one of them decided to go all-in on a fully playable Princess Luna, Season 1 style.
You can see her in action below!
As a general disclaimer, there have been a few bad-apple versions of FIM floating around over the years, so download at your own risk.
Thanks to Wright and ADX for the heads up.
