After solving the safe puzzle and getting the Colt handgun, go back down the stairs to the basement. While exploring, you will hear from the walkie-talkie a transmission to all units to be on the lookout for Wayside Inmates Transfer Bus, headed northbound on route 73 with 7 inmates and two C.O.'s, and that the Officer failed to check in and the driver's not answering the radio.
Reach a closed gate, and break the lock with your weapon. There is a note on the table that will add information to your journal, so be sure to pick it up as it will add some information to your journal. Pick up piece of wire from atop a container nearby. This piece of wire can be used as a replacement in a burned out electric circuit.
Go back towards the stairs, and you hear some commotion. An inmate there is punching some woman. You attack him in order to help her, but as soon as she is set free you realize she is a monster. She kills the other inmate and attacks you. Kill the Screamer monster. Use the first aid kit after the battle to heal yourself. Watch out for more screamers as you explore the house, as there might be additional Screamer encounters. Screamers can produce a high pitched scream that stuns you, so be careful.
In the basement, locate the platform with the broken panel. Open inventory and use the piece of wire to fix it. The platform will rise and take you outside. You will find yourself in the center of some town. Enter the house closest to you, and find the clothes on the bed. Pick up the clothes to change. You also find a police badge, and a rusty key.
On a shack nearby, you see the ticket machine. But power is out. Follow the wire to go out the back, and turn the lever on the generator to bring the power back up. Go to the machine and play the Jail Break Puzzle. Note that there are three holes on the top. One red, and two green. You need to get the red marble into the red hole, and the two green balls into the green holes. As the water level rises, move the colored ball to the left and right to get them into their corresponding circles. On harder difficulties, the Jail Break game will get filled with water at a faster rate. Once you solve this puzzle, you get the sky tram ticket.
Locate the big dumpster, and slip through the opening between it and the wall. Use the rusty key to open the gate and leave the area. You will be attacked by a group of Screamers.
