Rustil: Eternal Labyrinth Castle, a Steam game developed by Mr. Kamada, a faculty member in the Department of Game Software at College of Computing, Kobe Institute of Computing officially launched on Friday, March 13, 2026 at 4:00 PM (JST). After more than a year of continuous updates since its Early Access release, the full version is now available. Some of the game’s characters and weapons were designed and created with the involvement of our students.

Over a year of improvements leading to the full release

Since its Early Access launch, the game has been played by players around the world. The development team gathered feedback from the community and continued to refine the game through ongoing updates. After numerous improvements including balance adjustments and new features, the full version has finally arrived.

Students contributed to the production

Students from our school participated in the design and creation of select characters and weapons in the game. Through their involvement in an actual game development pipeline — from the planning stage all the way through production — they gained invaluable hands-on experience.

Going forward, we will continue to drive practice-oriented educational initiatives, strengthening ties with the industry and creating opportunities for students to build real-world experience while still enrolled.
