|“||The elevator delivered us to the top of the tower. For decades, news was broadcast from this place. But whether today's news would be good or bad, depended entirely on us. Once we installed the guidance system, our mission would be over, But plans were made to go wrong.||„|
— Level description
At this climax of the story Artyom and Miller begin their ascent of Ostankino Tower. The old elevator system breaks about 3/4 of the way to the top, and Artyom is sent plummeting down a few floors. He manages to hold on however to some rubble, and the resulting view shows just how serious this situation is getting. The climb back to Miller is short, but there are many demons for Artyom to evade. After some close calls, Miller manages to fight off the demons and Artyom reaches Miller. It is then that the last demon makes it's move and breaks through a tower wall; the demon injures Miller before Artyom can finish it off. Having to climb the rest of the tower alone Artyom makes several more ascents up crumbling ladders and frozen pipes. Several times the dark ones begin to speak to Artyom, not message of peace but this time of panic and frustration. Artyom eventually reaches the broken top of the tower and gets a full view of Moscow and Botanicheskiy Sad. Upon setting up the nuclear missile guidance system, the dark ones use their telepathic powers, attempting to stop Artyom, and a battle of minds ensues.
- A dark one is following Artyom and Miller during the ascension to the top of the tower, when Miller is injured the dark one tries to speak with Artyom; and later when he is in the top the dark ones use their telepathic powers to stop Artyom. Finally when Artyom shoots it and leaves the ether, the dark one's injured body is near to the missile guidance system supplicate desperately trying to stop the missile strike.
- The breathtaking view from the top of the tower reveals the extent of Moscow's destruction. Ostankino tower was very close to the epicenter of the blast, but is remarkably intact. Shrouded in smoke, the edges of the blast crater can just be made out; Moscow is significantly less ruined beyond this border, evidenced by the dense silhouette of intact buildings.
- According to Dmytro Zenin, the textures used for the devastation were based off satellite images of the streets, creating a somewhat accurate layout to what modern Moscow looks like.
- The Garden, where the "nest" of the dark ones are can be seen, appears to be slightly different in Metro: Last Light.
- Occasionally the demon that tries to attack Artyom in the elevator will not leave and simply stand there swiping or looking around. Because it is invincible the only solution is to load the last save.
