Metro 2033: Walkthrough → Delirium
At this point, we'll be overcome by hallucinations again. First, we'll find ourselves in the center of a huge well. There will be doors on all four sides. We can only reach them by following a straight line from the center to the doors. As we walk, a path will appear beneath our feet. If we stumble, we'll fall not only in the hallucinations but also into the towers in real life.
Of the four doors, we need to find the one with the red light and the Black One beckoning us. The next moment, we'll regain consciousness at the tip of a mast jutting from the tower. Then we'll find ourselves in another world again. Now we have to find a way out of the labyrinth. One of the Black Ones will be chasing us; we must avoid falling into his clutches.
The final challenge will be running through a tunnel that appears a few meters ahead of us. It's a beautiful sight.
At the end of the path, we'll meet Hunter, who will give us a pistol and tell us to exterminate the enemies. Which we do. We'll turn around and fire a few well-aimed shots at the Black One pursuing us. He'll fall, and we'll find ourselves back in the real world, witnessing one of the game's two endings.
The books on which the games Metro 2033 and Metro 2034 are based by Dmitry Glukhovsky.
