Afterward, move up and take the mounted machine gun turret as Helghast flood the area between your building and the next. Blast them all and then take the gun with you by hitting Triangle.
As you enter the museum, you'll encounter fairly heavy Helghast resistance — particularly around the corner to the left and up on the balcony. Use your heavy turret to take out as many as you can, as fast as you can, especially above you.
Move carefully left and sweep the area clean. Use the cover on the right side of the room as a good place to stop and open fire. You'll deal with light armor troops up here, and if you leave too many alive too long, they'll get brave and come try to stab you up close.
Head forward and you'll reach the stairs to an upper level. Clear the balcony ahead of you as you enter the open room ahead and push across to the far side. More stairs lead to the roof.
Take cover at the hole in the wall on the left and start knocking out the Helghast positioned nearest you. Your objective is away to the left, where there are a lot more troops.
Go to the door and go straight across to the corner of the roof ahead, where you'll find additional ammo and a good place to hole up. You'll have to clear the roof twice, as a drop ship appears to bring Helghast reinforcements to the next section. Watch the opening on the right.
When you're safe, make your way to the door up ahead and plant a charge. Blow the door and turn back to the right before going through — that same place that saw Helghast guys charging through to engage you will now cough up a couple more. Kill them and move through the door to the last section.
Mop up and cross the bridge on the right. You'll push through a residential area — melee the broken doors to get through them. A cutscene activates as you leave the building.
