The art book. Everything we've been pointing at — it's all in here.

Seven posts ago we started with the biggest image in this book. Here's the book.

The *Interstellar Sentinel* Art Book is 266 pages. It contains the concept art, environment paintings, character designs, and reference material that shaped this game from world-building to shipped product. Designs that didn't make the final game. Early iterations of enemies you fought. Visual arguments that were made, revised, and sometimes abandoned before a single line of gameplay code was written.

This series pulled 28 images from it. The book has more.

We've been a three-person studio building this universe since 2019. One developer, one game, one vision. The 97% positive rating on Steam came from players who found the game without press coverage, without major distribution, without a marketing machine. They found it because the game is good and because the community — you, the people at @drbosskey.bsky.social, the Discord, the Twitch chat — spread it.

Chris Huelsbeck scored 58 minutes of original music for this. 19 weapon sets, 55+ types, all designed to feel at home in the world the art defines. Eight environments built to feel real. It all came from the same place: the concept art in this book.

If you've followed this series and wanted to go further — this is where further is.

*Interstellar Sentinel* is on Steam and itch.io. The community is on Discord and Bluesky at @drbosskey.bsky.social. We stream Tue/Wed/Sat/Sun at 8 PM PST on Twitch.

Thank you for four weeks of this. The universe keeps going.
