The Last Way chapter in the 2005 video game, Shadow The Hedgehog, with music replaced from the anime, A Certain Scientific Accelerator, and two cut tracks from the game's original soundtrack. I still want an interview from the creator, the similarities between these two properties are too coincidental.
Tracks in order:
Dark Hero - A Certain Scientific Accelerator
Magna-Fi - Who I Am
Sins of A Divine Mother - All of Me
Back in 2017-2018, I beat all 326 stories in Shadow the Hedgehog, and in March that year I recorded a video showcasing proof of that. I wouldn't recommend doing it yourself as it is a HUGE pain in the ass, but I nonetheless had fun doing it.
