Bridge is the name of Chapter 24 in Metro Last Light and it can be played when Artyom finds a way to climb to the inner section of the bridge from The Crossing.
Bridge can be a very short mission, depending on how the situation is approached, but regardless, it only takes place on an abandoned bridge.
However, even if the chapter features only one hidden Diary Page collectible, it’s in an easy to miss place, hence the collectibles guide below uncovers its exact location.
Chapter 24 Description
BRIDGE
“Whatever my intentions concerning him might be, the little Dark One just does not seem to care.
He keeps following me as if I never was going after him, as if we were tied together by fate…”
Diary Page
Cross the bridge while dealing with the enemies (if you play as stealthy as possible and you choose not to kill a single one of them you can unlock an extra achievement/trophy).
As soon as you reach the inner part of the bridge, away from the storm, you can clearly see some escalators a few meters front of you.
Check for a door on the left side of the area (look for a gas mask painting on the wall) and get inside the small office to grab the Metro Last Light Bridge Diary Page collectible from the desk.
“But I remained human. I was afraid to be different, afraid to be considered abnormal… I was the only one free from their influence, but I suspected myself to be a sleeper agent of the monsters…
The meeting with the Dark One just got displaced from my memory. The beast within me woke up and devoured the human. I went out to the surface an orphan, yet I came back a firstborn son. I was to create a connection between the angels and men, and instead I targeted the missiles at them.
There was only one survivor. And now he stands before me. A child. An orphan. Alone in the whole world. The circle is complete.”
The chapter named Depot becomes available after you use the zipline to traverse the bridge and you are rescued by the Dark One.
