The goal of this Easter Egg is to destroy a Cargo Ship off the coast in the past, before the virus goes loose in the city. To do this, you will need to charge a Time machine, this being the main focus of the Easter Egg.

Step 1: Turn on the Power. This can be done by turning on 5 generators.
Generator 1: In the spawn room, right in the middle.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177700930

Generator 2: In the area with the Urn Cleansing table. In the middle of the area. This is also 2 doors away from spawn if you open the single door in spawn, and the boxes straight ahead (one of the boxes leads to double tap, you should be able to see the generator from where the path splits on one of the sides).

Generator 3: On the complete right side of the Main street. To the right of Dr. Carbine's room.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177701918

Generator 4: In the market area by the starting box location.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177702601

Generator 5: Up by the fountain to the north of the market area.

Step 2: Shoot the skulls around the map. (This might not be required, but I'm almost sure that it is)
There are 8 skulls around the map that must be shot.
Skull 1: In the spawn room, on a box next to the generator.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177700930
Skull 2: In the Double Tap area, on a box between 2 cargo crates.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177701068
Skull 3: By the Urn cleansing table, on top of a makeshift roof out of sheet metal.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177701415
Skull 4: In the Cargo area, next to the switch behind the open cargo crate. This one is on the ground.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177701567
Skull 5: In the Juggernog area. Between Jugg and the Main street, is a pile of rubble on the left side. Poking out from the rubble, on the left side of the rubble, is the skull.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177701711
Skull 6: On the main street on the left side on top of some girders. By Deadshot I believe.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177702109
Skull 7: This one is tough to see. It is inside of the toilet closest to the Main street and the MPL wallbuy. It is in the bowl. You probably won't be able to see it, so make sure you listen for the noise to know you got it.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177702316
Skull 8: By generator 4 and the starting box location. When entering the room, turn right and it will be on the ground in front of the barrier.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177702458

Activating all 8 of these skulls will spawn G-Strikes near Generator 2. This will probably also allow a future step to start.


Step 3: Activate all of the switches. These switches look like the Afterlife boxes from Mob of the Dead.
Switch 1: In the spawn, to the left of the m14.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177703578

Switch 2: By generator 2, looking North, on the path to the left.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177704183

Switch 3: In the room between the Urn Cleansing table and the Cargo Area.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177704325

Switch 4: In the Cargo Area, behind the open cargo crate.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177701567

Switch 5: On the Main Street, by Dr. Carbines room, to the left.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177704497

Switch 6: In the Speed Cola room.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177704635

Switch 7: In the bathrooms.
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177704961


Step 3.5: Activating these switches will do 2 things.
1: Ability to talk to Dr. Carbine
2: Charge up the Time machine by 25%

Step 4: Talk to Dr. Carbine, and complete his request.
With the switches turned on, you can now talk to Dr. Carbine in his room on the Main Street. His house is the one next to the big question mark.
He will request that you bring him a syringe and a health pack.
The location of the syringe is in the bathrooms, on a lone sink across from Mule Kick.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177705604 ( i already took it, but it was there)

The location of the health pack is on a box, next to Stamin-up, and by Generator 4 and the start box location. The model is a bunch of pill bottles.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177705803


Bring these Items back to the door, and Dr. Carbine will give out a single Ray Gun Mark 4, being a ray gun- shotgun hybrid. In Co-op, only one player can grab this.

Step 4.5: Ask Dr. Carbine for hints by going to his door. He will mention that the Urns around the map contain energy. On the second hint, he mentions that filling the fountain with blood will release an Evil.

Step 5: The Urns. To do this, you need to take 4 urns from around the map, and cleanse them on a table near Generator 2. The Urns spawn in order, and never change location.
Urn 1: On a box near Double Tap. It will be glowing green. Take this to the cleansing table, and set it down. Some extra zombies will spawn in, but the cleansing is time based. I think. After it cleanses, return it to the same spot.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177706421

Urn 2: In the Market Area by generator 4. Same thing as the first Urn.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177706739

Urn 3: Inside of the Speed Cola room, on a box close to the perk machine.
The screenshot I took got deleted, but you should be able to find it.

Urn 4: In the spawn room, on a box close to the M14.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177706865

Once all of these Urns are returned, this will charge up part of the Time machine.
This will also lead into Step 6.

Step 6: This requires Step 5, and possibly step 2. In the Spawn room by Quick revive, a floating skull surrounded in blue light will spawn. Press your use key, and it will move location. It follows the same path each game.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177707515

It starts next to quick revive, moves to the second room by the B23R, to gen 2 area, through the room between the Urn table and the Cargo Area, To the Cargo Area, by the Turret, by jugg, to gen 3, all the way down the main street, to the power station area, through the market, and finally ends near the church.
This will charge part of the time machine, and allows the bloody bucket to be picked up.

Step 7: You will want to be set up for this part. The best weapon to have is the Ray Gun mark 4 upgraded. In this step, those really fast Brutus-looking guys will spawn non-stop until 4 portals are shut down around the map. The Mark 4 is very good at killing them with headshots. Stamin-up is heavily recommended.
Step 7.1: With the completion of step 6, the bloody bucket at the end of the Main street, by generator 3 will be glowing green. You can now pick this bucket up. To start the next step, which is very difficult if not prepared, you have to throw the bloody bucket into the fountain by generator 5.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177707702

Step 7.2: This is very easy with 4 people, as there are 4 portals to close, and if you can get all 4 players to stand next to a portal, it can be ended very quickly. I recommend saving 1 zombie at the end, so you don't have to worry about 20+ extra zombies chasing you along with the boss zombies.
When you throw the blood into the fountain, it will wait about 10 seconds, and say how and evil has been released. This is your cue to close the 4 portals around the map. These portals look like Shadows of Evil Rift portals, and they always spawn where the piles of Mini-Squids are.
I do recommend getting the portals in this order, as to not get 20 of the bosses trapped in spawn with you.
Portal 1: By the Church, close this one first as it is closest to the fountain.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177710112

Portal 2: In the spawn room, to the left of the M14 wallbuy.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177710325

Portal 3: By the cleansing table

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177710497

Portal 4: At the end of the Main street, by gen 3.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177710685

Once all portals are shut down, take out all of the boss zombies, and no more will spawn.
This will finish charging the time machine.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177710894

Step 8: Use the Time Machine.
The time machine is located inside of the church. Once activated, the map will turn black and white.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177711168

All you need to do in this mode is head over to the turret gun, and press the console.

https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1177711482

Pressing the button will activate the turret, and cause it to shoot the cargo ship.

The Easter egg will be completed. The time machine effect will be completed, and you will be rewarded with all the perks, and a buyable ending will be located at the spawn room for 50,000 points.

Congratulations.
