Quake 4's canceled expansion, The Awakening, is playable in openQ4 0.14.1. Raven Software and Ritual Entertainment worked on the campaign before it was shelved. Justin Marshall recovered and published the alpha, and the openQ4 team got all 13 maps running on its own game code, rebuilding the expansion's monsters, weapons and vehicles. The port repairs several broken encounters, including the Valkaryne finale and the death-ray turret on the beach.

The expansion sits alongside the original campaign under Single Player > Campaign and keeps its own saves and settings. You'll need a copy of Quake 4 and the separate expansion files. The setup guide explains where to put them. The team is still testing full playthroughs.

The release also adds Vulkan support on Windows, softer and steadier shadows, redesigned menus and HUD, and bots that can follow team orders. There are Windows and Linux builds, a preview for Apple Silicon Macs, and an experimental Android build.
