After the scene, follow Lev until you reach a waterfall, then go into the Barbershop on the right to find a Coin 18/32 on the counter, now jump across the water to the buildings on the right and then go upstairs to find an Artefact 95/117 on the floor.
From here, smash open the window and head out onto the balcony, then go up. Drop down onto the highway, then jump into the apartment on the left and grab the Artefact 96/117 from the table, now go into the room on the right and open the safe by inputting 30-23-04.
Exit the room and climb up onto the roof, then drop down onto another balcony. Here you'll want to take down the enemies and then use the crashed vehicle to go back outside, now jump across and go into the Interbay Store. Use the workbench on the left, then grab an Artefact 97/117 from the body by the counter before going through the window and jumping across to the next building.
Here you'll want to go out the window on the right to find a Coin 19/32, then follow Lev up higher. Eventually you'll enter a room that contains loads of computers, grab the Artefact 98/117 from the desk, then climb up two sets of ladders to reach a shrine.
After you're done examining it, use the workbench in the room on the right, then climb up another ladder and take down the enemies here. Once the enemies have been taken down, use the lift to go higher, then when you exit you'll find an Artefact 99/117 on the wall ahead.
Finally, follow the Lev across the crane and then you'll eventually fall down into a building.
