Progressbar Popup Fighter is a spin-off game of Progressbar95, initially released on 22 December 2020, developed and published by Spooky House Studios. It is about not overwhelming the CPU with a lot of pop-ups; if it gets overwhelmed, a BSOD will appear. Even though the game received some updates that added new content and features, it is safe to assume it has been abandoned due to the lack of updates and discussion about it.
