Find Maeda in NYPD and listen to his stupid talking. Go to the hospital and get the stupid good luck charm from Maeda. Go to NYPD again and give Wayne the good luck charm. This time, go in the hospital and make sure you get the tool in the closet near the door. Go left and get in the elevator. Watch Eve's meanness. Find the 3 fuses, autopsy key in the desk, and the blue cardkey from the dead guy. Note: this takes forever and is really boring. Use the blue cardkey to get to the fuse box. Note: you should only have 2 fuses now. Fuse box: put in the fuses, repair the wires, and turn the power on (if you do this in the wrong order, Aya gets zapped but doesn't die, if you haven't seen it yet, I suggest you get zapped). Go find the 3rd fuse and put it in the fuse box. Go back up the elevator and go right then up. Get the green cardkey from the nurse after you watch the doctor with his patient. Go back and open the door near the elevator with the green cardkey. Go up and get the treasure, then go down and close the valve. Then, get in the elevator and go to the 13th floor. Find room with the door that won't open and go to the left. Push the junk over to get to the red button, after you push it, go in the door. Search the clothes and papers near the sperm. Get in the elevator to go to the roof and watch the planes take off. Kill the spider on the roof, then watch Eve screw up some pilot. Run as fast as you can to the bottom left corner and get on the thing that falls. Note: if you don't get there fast enough, you will die. Talk to Maeda and Daniel and then go to the NYPD and talk to more people. Good luck with day 5, you're going to need it.
