Quake Brutalist Jam began as a celebration of old-fashioned shooter level design, but its latest version is one step away from being a game in its own right

A lone concrete spire stands in a shallow bowl of rock, sheltering a rusted trapdoor from the elements. Standing on the trapdoor causes it to yawn open like iron jaws, dropping you through a vertical shaft into a subterranean museum. Here, dozens of doors line the walls of three vaulted grey galleries, each leading to a pocket dimension of dizzying virtual architecture and fierce gladiatorial combat.

Welcome to Quake Brutalist Jam, the hottest community event for lovers of id Software’s classic first-person shooter from 1996. First run in 2022, the Jam started out as a celebration of old-school 3D level design, where veteran game developers, aspiring level designers and enthusiast modders gather to construct new maps and missions themed around the austere minimalism of brutalist architecture.
