Sludge Life

Sludge Life is an open-world adventure game based on graffiti, parkour, and urban culture. Initially equipped with nothing more than a spray can and laptop, the player must leap and climb to find preset locations for tagging in order to further explore the environment. Tagging (especially difficult tags) enables the player to gain respect from other taggers and eventually allows the player to co-operate with a series of murals. A handful of items found around the world can provide the player with new gameplay features: a camera that can – aside from taking pictures – reveal tagging locations, a glider that can extend the player's airborne distance, a teleporting device called the "warper" that allows the player to place a marker down and teleport back to it any time, and a pair of "vandal eyes" floating in a jar that always look towards the closest tagging location.

), and the player can play basketball, smoke cigarettes, eat some of the food lying around, and "zoom" (the term for using psychedelic mushrooms). There are 100 tags to spray and there are three possible endings. The player cannot die, although there are a handful of environmental hazards – such as fall damage – that will knock the player out causing them to reawaken in a hospital bed.

Sludge Life is based on the efforts of a graffitist to be recognized by his peers. Set in a fictional 1990's-era oil rig/shipyard, the main character, Ghost, spends time meeting inhabitants, exploring, and spray-painting tags and murals. Exploring the rig and talking to other characters can reveal some of the world's backstory, including secrets about the megacorporation Glug, and revealing a strike against Glug protesting the death of the corporate mascot, Ciggy.

While climbing and exploring the rig, its environs, and the buildings on it, Ghost is able to find three possible endings:

Sludge Life was developed by Adam Drucker AKA Doseone and Terri Vellmann from Devolver Digital. Previewed at 2020's PAX East (29 February – 1 March), the game demonstrated an emphasis on graffiti, music, resistance, grime, and crass humor. Notably, however, the game was dramatically less violent than the developer's previous High Hell (and later Disc Room). In fact Vellmann's first conception of Sludge Life would be to remove guns entirely.

Focusing on NPCs rather than enemies, Drucker and Vellmann began to develop personalities in the new game. Characters were designed based on real people the developers encountered. As ludic aspects developed, Drucker drew from activities of his youth, including running, climbing, and street art. To emphasize the visual aspects of graffiti and its spatial relationship vis-à-vis the observer, parkour became a primary theme.

After its initial 2020 release as a free game on Epic Games Store, numerous reviewers encouraged players to test Sludge Life. The second release (allowing Switch and Steam) in 2021, provided additional reviews to examine the game again. Recognized for its laissez-faire exploration which the developers described as a "walking simulator", early reviews emphasized the humor in the game as well as its strange mood/atmosphere. The game was compared to 2000's Jet Set Radio in its themes, but otherwise more similar to visual media like the programming from Adult Swim or Liquid Television from the mid-1990s.

From the initial 2020 release from Epic Games Store, reviewers emphasized the game as having a niche and unique/eccentric vibe. The 1-year free price was also broadly appreciated, and the game was praised for its gameplay and the music. Criticism was primarily limited to controls which were found to be "wonky", however additional criticisms came in the form of its relatively short length and the inelegance of developing its uniqueness. Hardcore Gamer gave the game a score of 4/5.
