Step 1 "Electrical Inadequacy" -

*Requires Dead Wire Pap Weapon* Purple Orb is always at spawn where you start. Your gonna use your Dead Wire Pap weapon and it will move and stop every time, Keep Shooting at it till it goes and will open the Insufficient power door that leads to downstairs to Observation Floor.

Dogs would be spawning while your shooting the orb. In my opinion, when your getting the Tesla gun, you can kill these dogs to charge the power that requires dogs at spawn.




Step 2 "Language Barrier" -

Travel to 1983 and there are 6 locations of symbols, one of em would show a glowing lighting symbol like a Revelations Symbol, when you see one, keep that in mind and go to the "Observation Floor" to travel to 1951, go to the symbol panels and press the exact symbol that you've seen before on one of the walls. Your gonna travel back and forth to do the same thing 3 times the symbol would change and change locations sometimes it would be in same wall spot or same symbol, once you've press the exact symbol 3 times, the door will open for you to press the panel and you've complete it and your ready to move on to the next step.

If you mess up by pressing wrong symbol it would give you a zap screen which means your gonna have to travel back to make sure to look, keep the symbol in mind and try it again.

Symbol locations: West Stairs, Prison Cellar, East Stairs (If your not sure to find em all, don't worry the video link is right there for you to watch.)




Step 3 "In-line with the Times"

*Requires Tesla Gun need to be pap* Your gonna travel back to 1951, your gonna go outside near the Offices, you'll see the crate. Your gonna use your Grenade to drop to the ground to break and there it will be a panel. Your gonna press the panel 2wice to activate. Once you do that, right next to the panel there 4 conductors, your gonna use your Pap Teslagun and zap it in the very center and the electric will shoot into the sky.




Step 4 "Chronologically Challenged"

You will be taken into the time travel and all you do is just follow the path that'll lead to the teleporter that will lead back. It'll cool for 1 min till its ready to say (leave) and your rdy to move on to the next step.




Step 5 "Caught up to speed"

Your gonna have look around the map to look for 4 alarm one of em would be at 1983
and the rest at 1951.
Sometimes you will see the Walking Zombie that will have a Alarm clock attached on you will kill it and clock will drop.
Clocks might float around somewhere per round not 100% sure on that. which you can go for a round and keep looking around the map till you find it.
Once you got all 4 clocks, your gonna go to the spawn, and place them next to the teleporter and you completed this step.




Step 6 "Lack of Coordination"

*Requires Dead Wire Pap Weapon* Make sure you use every teleporter to travel back & forth.
Your gonna travel to 1983, your gonna hear that familiar sound effect thats from Der Riese
when a power is out when you start the game.
It means the 4 teleporters are not available to travel back to 1951.
There are 4 coordinate stations, your gonna need and shoot the conductors with your "Dead Wire" weapon.
Begin 4 Coordinate searches and it'll do a short lockdown. When the lockdown is over, you will grab the tape and go to your next one.
Once you got all 4 tapes, you will place em each every table next to each teleporter
which they'll let to travel back to 1951 and you have completed this step.

Coordinate Searches Locations: Hallway near Offices, Lower Cellblock, near Cafeteria & East Stairs & Prison Cellar


Step 7 "Timeline Diversion ahead"

All 4 teleporters need to be hold "Square" or "F" on to configure the connection. and your pretty much done the Easter Egg.




Final "Reversion of the Unity"

Spent 45K on Teleport to escape, run and follow the path to the Portal.
