After he reaches the station, DeWitt must find a way to reach the Monument Island.
This is the first mission that features a new addition to the BioShock series, the sky-line system, which is a very fast method used to travel within the game world.
Players who encounter difficulties in locating every BioShock Infinite collectible in Monument Island Gateway should use the information in the following collectibles guide.
Immediately after you enter the station, turn right. You should see the first BioShock Infinite Monument Island Gateway Kinetoscope between the benches (where you see the two posters).
Uncanny Mystery in Columbia
The only BioShock Infinite Monument Island Gateway Telescope is very easy to miss because of its position. After you exit the gondola station, you need to use a gondola to reach Monument Island.
Unfortunately, the gondola isn’t working, so the new sky-line system is introduced to you for the first time. You can use the grappling hook attached to your arm in order to access the sky-line rails.
Therefore, grab the rail and pay attention, because at some point during your ride two enemies attack you and you need to quickly jump onto their balcony.
Finish them and then look through the Telescope located on the same balcony.
Shortly after you pick up the previous collectable, your path on the sky-line is blocked, so you have to find a way to clear the freight off the tracks.
The lever is in the room thats on the right side, and if you go inside you can see theres another smaller room to your right (as you enter).
In this room is a desk which holds the first BioShock Infinite Voxophone hidden in Monument Island Gateway.
