Passage: A Hat in Time is a platform action-adventure video game developed by Gears for Breakfast for macOS, Microsoft Windows, PlayStation 4 and Xbox One. The game was developed using Unreal Engine 3 and funded through a Kickstarter campaign, which doubled its fundraising goals within its first two days.  It is inspired by earlier 3D platformers such as Super Mario 64, Banjo-Kazooie, Spyro the Dragon and Psychonauts. The game was self-published for Microsoft Windows and macOS in October 2017, and by Humble Bundle for the PlayStation 4 and Xbox One consoles two months later. A Nintendo Switch port will be released at a later date.
