Chapter 04 - Comstock Center Rooftops

Blue Ribbon Restaurant

There are three kinetoscopes set next to each other inside the restaurant. Make sure to view all of them. Clean out the area of loot as always before speaking to Madame Lutece to receive the Shield Upgrade. This keeps Booker's health from being depleted for as long as the shield is active. Should it shatter, all you need to do is take cover until the meter is refilled. Incredibly useful stuff.

Heading into the kitchen, pick up the Voxophone from the counter before going outside. There, walk to the edge and look up to spot the freight hook that you must grab to proceed. Kill the oblivious cop on the building below you before dismounting ans grab his Machine Gun. There are ammo boxes nearby for yourr new weapon as well. Now, follow the objective arrow to the Lansdowne Residence while fighting your way through more Columbia Protectors. There will be a few gun turrets around that you can take advantage of with Possession or destroy. It's your choice.

Lansdowne and Montgomery Residence

Apart from ordinary loot, there is a Voxophone in one of shelves at the bed room, plus a locked chest. The key for it can be found within the Fraternal Order of the Raven. Just examine the chest so get the optional quest for the key. Go outside and hook over to the Montgomery Residence. There is nothing particularly noteworthy in this house so just pass through and go outside.

There are cops patrolling outside though and it can lead to quite a bit of riot when they see you. This big encounter caps off with an encounter against a Fireman.

Once you're out, head to the small stage on the grassy area where you'll find a Voxophone. Also keep an eye out for a large white tent off to the side of the grassy area. Check behind that tent for a kinetoscope. Follow the objective arrow to the next section.

Fraternal Order of the Raven

Explore and loot base while killing a few cultists. Stop by the tavern to grab the Voxophone from the bar. Next head for the chapel and face off with a rather large army of cultists. Once the room is clear, take the Voxophone on one of the pews then check the altar for a Health Infusion phial plus the key to the locked chest in the Lansdowne Residence.

With the key in hand, you can now bactrack to the Lansdowne Residence which shouldn't be all that far from here. That chest contains another Health Infusion and some Salt.

Back at the cultist base, follow the objective arrow to the elevator and riding it down to another floor. There, enter the room across from the vending machine. Look at the desk for a Voxophone.

Upon entering the large room that has a projector on the table, you'll want to move the white bookshelf aside to gain access to a hidden room that has a Gear in it. Clean out the items in the room before going outside to face the new Crow enemy.

These things are vulnerable to explosive traps from the Devil's Kiss which means that you need to hold the Vigor button instead of just tapping it to set the trap. Pick up the Murder of the Crows Vigor after you kill him. Proceed to the next room after dealing with the Columbia Protectors. There, check the floor next to a broken vending machine to find a random Gear.

Continue outside to a balcony and jump on the police barge in front of you. Use the telescope to add to your Sightseer progress. Traverse the freight hooks and proceed to the Gondola Station.
