No One Escapes Alive Achievement

Each step will require you to use the afterlife. While you can do this solo you can get it completed much earlier with more players.

Step 1 - The Warden's Key
The first step is to get the Warden's Key. You will see it hanging and electrified in one of the cell blocks. Go into the afterlife and there will be a portal up top next to a computer console. Shock the console and the electricity should drop. Press  to pick up the key.

Step 2 - Open The Roof
You want to go ahead and open the roof as soon as possible simply because you can only hold one plane part at a time. You will need to go to the bathroom(?) and then there will be a locked door with a Roof sign lit up. You need to go into the afterlife and through the portal which leads to the roof. There is a power box you will need to shock then the door to the roof will open.

Step 3 - Uniform
Location - Laundry

You want to travel through the cell block ground level and go down the passage to Laundry. There will be a bunch of bodies hanging in the room and off to the side you will have to open a gate with the Warden's Key. Then go over to the shock box on the opposite corner of the room and travel back to the gate and shock the power box. Return to your body and wait for the washing machine to finish. Grab the uniform then attach it to the plane.

Step 4 - Rigging
Location - Spiral Staircase

You will want to travel through the catacombs until you see a spiral staircase. You need to use the Warden's Key to open the box at the bottom and then spend 1000 points to open the door to the left that seems to lead to nowhere. Travel back up to the top and use the shock box. As you travel back down the spiral staircase you will see numbers on the wall. Remember all 3 numbers and then shock each box at the bottom the appropriate number of times. The glowing platform will then drop. Return to your body then go through the door you opened previously at the bottom. You will be able to open a gate and grab the next part.

Step 5 - Propane Tank
Location - Docks

You will need to hit the power box with electricity in the afterlife for the gate to open. It is timed however so you will need to make it quick.

Step 6 - Engine
Location - Warden's Office

For this one you want to go down the spiral staircase and unlock the gate that has all of those computers. Go into the afterlife and shock the two computers until the lights go out then go through the portal and shock the third one. Return to your body and head to the Warden's Office. The door that was previously electrified will be open and you can grab the part.

Step 7 - Control Valve
Location - Next to Deadshot Daiquiri

Next to Deadshot in a glowing green case.

Step 8 - Final
Now just build the plane with all the parts and press X to fly. When on the bridge you can return via electric chairs. In order to fly again you will need fuel cans but those are found in the same spots as the plane parts. You won't have to do any afterlife stuff anymore.
