At a certain stage, it was planned to expand the world of the shooter.
Recently, Justin Marshall presented online the gameplay of a "rare prototype" - an add-on for Quake 4 that was never released.
Judging by the presented footage, players in The Awakening were expected to see dark locations. Some assets and mechanics look unfinished.
Justin Marshall explained that this material is published "for history":
It demonstrates the early stages of development - content, locations and gameplay elements that were eventually cut before release. This video provides a rare opportunity to see what The Awakening add-on could have been and imagine how it could have expanded the original Quake 4.
