This absolutely rocks and I love it, although it is a bit difficult imagining this as a end credits theme. It definitely fits in a steampunk AA game, but it feels more akin to a reveal in the story or a transitional song. The piece is very cohesive and flows well, it's very well done in that regard. The sound design and overall soundscape of this just feels so good too, you did a really good job making this feel immersive to your world.
