Francis is a grumpy old bear who gets a chance at settling up on his massive debts when he is referred to The Alpha Underground. All he has to do is sign away his rights and become a guinea pig for some weird experiments held by a perverted yet genius scientist.

Developer Notes:

—

This is the full release of The Alpha Underground! The game should take around 2.5 hours long, and is just a part 1. This VN is currently not in active development, but if this does well enough, I will consider working on more, including having route splits that focus on different characters in The Underground.

All of the art and writing was done by me! You can find me on Twitter or Bluesky.
