| Jun 7, 2026 | Katanaut Patch 1.133 Hey all! As per usual, while I was working on porting to consoles, I came across some wild performance hacks that also work great on PC. This patch is lumping in some of those performance increases which should wildly help lower end PC's, and also maximize FPS for everyone across the board. Also lumping in a few bugs and QOL feature reported on the Katanaut General Discussion |

Seeing the item combos people are using (through the leaderboard) is opening up a lot of great opportunities for balance adjustments. I’m really happy to see such a wide variety of builds!

| Apr 5, 2026 | Katanaut Patch 1.120 You might be thinking... What is this solo dev doing. He just patched the game yesterday, and now he's dropping a MASSIVE 200MB patch. WTF. Well, I just had a massive breakthrough in performance for Katanaut while working on the porting efforts for Switch. These performance updates are significant under extreme testing, and I'm so incredibly happy about them, that I'm here patching this in at 2am. |
