Sludge Life is a first-person graffiti platformer game developed by Terri Vellmann and Doseone and published by Devolver Digital. It was released May 28, 2020 for free on the Epic Games Store for PC. A Nintendo Switch port is planned for release in 2020.
Taking place on small, man-made island built over an endless expanse of 'sludge', Sludge Life has the player filling the shoes of a graffiti writer known as 'Ghost' navigating its world in order to complete 100 tags.
The gameplay of Sludge Life is largely that of a non-linear 3D platformer open world. All 100 of the tags the player can find and engage with are pre-determined artwork that fit their location. The challenge is in figuring out how to get to specific areas in order to engage in the tag.
The game also features a virtual desktop that serves as its pause screen. Multiple apps can be added to the desktop, including minigames and tools, that are found throughout the world.
