Dr. Maxis will tell you to turn off the power after turning it on. With the power off, you will need a player to use the Turbine to open the door nearby, allowing everyone to leave the Power Lab. Dr. Maxis' side can be done with just 2 players.

Step 4 - Go to the Transmission Tower

Remember, Steps two must be done before doing this step!

The transmission tower (Commonly called an Electricity Pylon in some countries) is a large steel structure in the Corn Maze. The Corn Maze is an area between Bus Stops three and four, which is the Farm and Power Lab. Since it's between bus stops, Denizens will attack everyone. The Galvaknuckles are very useful against these guys. If you get lost, look into the sky for the large tower.

Step 5 - Kill Him

Survive until He comes to the tower. Once he shows up, use two turbines near the tower and kill him inside the fence with an EMP Grenade or Galvaknuckles. All of these must be used to fully kill it. Maxis will say you need more power if done correctly.

Step 6 - Use Turbines

The final step is to send two players to two different street lights with their turbines (you can remove the turbines from the tower if you only have two players). Have two players place their turbine next to a street light, and the Achievement / Trophy should unlock. The players may need to go at specific street lights. The ones we've seen were at the Rest Stop (gas station & diner) and at the Bus Stop (starting location).

For those who don't know, there are several street lights on Green Run. They are located at and in between bus stops. Using Turbines on the street lights will turn a green light on. If a Denizen walks under it, a portal will open, allowing players to jump from one spot on the map to another.

Step 4 - Start Building Special Equipment

Special equipment can be built at the fifth bus stop (Town) before taking on Him. Unlike all the last Buildable Equipment, these pieces must be collected between bus stops. It's best to collect them after getting decent perks and weapons. These two items are the Thrustodyne Aeronautics Model 23 and the Navcard Usage Machine.

Use the Thrustodyne Aeronautics Model 23 on the Navcard Usage Machine until the Element 115 rock is heated up. Dr. Richtofen will tell the team to go to the Transmission Tower (AKA Pylon) next.

Wooden Board - Under the stairs by the work bench at Power Lab / Demolished Building
Control Panel 2 - Leaning against dumpster beside mystery box location in the Town (Area 5).

Step 5 - Kill under the Transmission Tower

The transmission tower (Commonly called an Electricity Pylon in some countries) is a large steel structure in the Corn Maze. The Corn Maze is an area between Bus Stops three and four, which is the Farm and Power Lab. Since it's between bus stops, Denizens will attack everyone. The Galvaknuckles are very useful against these guys. If you get lost, look into the sky for the large tower. Kill many, many zombies until Dr. Richtofen speaks again. Mostly Just 1 Round Should Be Enough or Less.

Step 6 - Reduce Power

Richtofen will say there's too much power and it needs to be reduced. All four players must now go to four different street lights around the map. There's one at each bus stop and sometimes one between bus stops. Some may require a turbine to turn the light on, and some are always on. Each player must take a Denizen underneath the lit street light to create a teleporter in the ground. When all four players have a teleporter next to them, they must all throw an EMP Grenade inside at the same time. If this is done right, the light from the teleporter will glow blue and swirle around the light and the achievement / trophy will unlock.

Part 5 - Get The Balls Wet

Richtofen will tell you to get the balls wet. To do this, build the Sliquifier and shoot each one until they start spinning. It may take two magazines each.

Part 6 - Make a Sacrifice

This step requires four Trample Steams. Build one on the table in the first building, and have all four players grab it. All four need to be placed on four more gold symbols around the map. Three symbols are located on the rooftop of the second building, and one is located near the elevator just outside the starting room. Make sure you aim them so they fling zombies at the satellite tower. When enough are killed, the step will be complete.

Part 7 - Power Up the Satellite

This final step requires at least one player to buy the Galvaknuckles. Remember, they're inside the elevator shaft in the upside down building. The player must hit the four corners of the satellite tower on the rooftop of the second building until it glows blue. The order the corners must be hit is randomized. You can figure it out based on seven or eight small white tiles hidden around the map, but it would probably take longer than trial and error. Activating the tower will complete the Easter Egg and unlock the High Maintenance achievement / trophy.

Part 5

Kill zombies in the Buddah room until maxis says reincarnation. Can be anywhere from 1-6 rounds, possibly longer.

Part 6

Get the Krauss Defibrillators (upgraded Ballistic Knife) with Samuel and have Rusman down himself in the Buddah room from grenades or a zombie and make sure he has Who's Who. Have Samuel shoot Rusman with the Krauss Defibrillator.

Part 7

Have two players grab the balls from the lions. Have everyone except the two players with balls put Trample steams down on the symbols with lions on them and face them at the tower. There is one in the spawn room, one in the back area where you find the circuit box for the nav card machine, one next to the two elevators near the claymores, and another down one floor from the spawn at the bottom of the stairs. Make sure the two players without balls have the trample steams put down correctly. If they do, they should not be able to pick them up. Now the other two players with the balls should put their trample steams down on the symbols and place the ball on the trample steam before it is ready to use.

Part 8

Use galvaknuckles to hit the beams on the tower. It is down exactly the same way as the Richtofen path, using the mahjong tiles as the key to which beams to hit. Once this step is done, the achievement will be unlocked and you will be granted 6 perks just like the Richtofen path.

Step 1: Build The Noose

The first thing you need to do is collect four parts around the map and build a noose near the Courthouse. It doesn't matter which order you collect the parts in.

Antennae in Stable near hay
Wire on a spool in Gunsmith Shop, near the tunnel's entrance to the Bank
Light Bulb on second floor of the Jailhouse
Battery in the Church near the pedestal
Step 2: Charge and Destroy Orbs

The next step requires the Paralyzer from the Mystery Box, the Subsurface Resonator equipment, and the Turbine equipment to power the Subsurface Resonator. The Subsurface Resonator is built from four parts from the General Store. See either the Buried page or the Buildable Equipment page for images of what each part looks like.

When you have the weapon and equipment, you'll need to charge four glass orbs around the map with the Paralyzer until you hear a chime, then destroy them with the Subsurface Resonator. The four locations are:

Left of the Church's front door
Near Saloon
In tunnels near Quick Revive room
In back of Mansion at the outside
Step 3: Obtain and Fill the Lantern

After completing the last step, a lantern will fly around the map. Get it down by cooking a grenade so it explodes right next to the flying lantern. One of the players must then pick it up and fill it. To fill the lantern, you will need to kill zombies around the player holding it until Maxis speaks again.

Step 4: Find and Decipher Code

With the lantern filled, you will need to place it on a glowing lantern symbol at the top of the Gunsmith Shop. Jump over from the Saloon's balcony to reach the rooftop with this symbol. A code of some sort will appear on the wall nearby that gives you a hint to the next step. This code will change between five available codes on each game. This code will give the names of three out of five signs around the map. These signs will have a name clearly written on them, so it'll be easier to know which to hit first. See the image below for the code and name of the sign.

You must hit all three in the order they are listed with the Galvaknuckles or Bowie Knife. Before you do this, make sure one player has obtained the Time Bomb from the Mystery Box.

Step 5: Escort Soul to Noose

This step is tied in with the last step. You will need to hit all three signs to unleash some sort of energy. It may be a lost soul. Make sure one player has obtained the Time Bomb from the Mystery Box before unleashing it. Drop the Time Bomb, then hit the third sign.

You will need to escort this soul all the way to the Noose. To keep it alive, run it through some Zombies on the way. Reach the Noose to illuminate one of the light bulbs. When it's lit up, activate the Time Bomb to do it again. The first light will remain illuminated, and now you must illuminate the others. Escort the soul again until all light bulbs are lit.

Step 6: Use Service Bells

This step requires all four players to split up into four areas: the Confectionery, the Stables, the Courthouse, and the Haunted Mansion. The first three buildings have three service bells inside each one, making a total of nine bells on the map. The Haunted Mansion contains a wooden board with nine lights, each light corresponding with a bell. The light board is located on the second floor of the house near the maze entrance. When a light turns yellow, tell one of the players to ring that particular bell to turn the light green. Light up all nine lights to complete this step.

Step 7: Target Practice

The next step is to Make a Wish on the fountain. To do so, you will need the Prisoner to smash the fountain by giving him booze. An option to make a wish by holding the reload button on the fountain will appear. Now it's time for Target Practice.

Targets will appear around the Haunted Mansion, Courthouse / Confectionery area, Saloon, and Jailhouse. All four players must hit all these targets without missing one before it disappears. Overall accuracy doesn't matter, just make sure it gets hit. If all targets are hit, the achievement / trophy will unlock! All Perk-A-Colas that can be found on the map will be permanently unlocked, as well.

Optional Step: Ending

Complete the Maxis sides on all previous zombie maps to gain access to this ending. Interact with the button in a box at the back of the courthouse to see it. The game will not end, and no other achievements / trophies will unlock. However, Richtofen will appear as a blue-eyed zombie from time to time and always drop a Power Up when killed.

Step 1: Build the Guillotine

The first step to this Easter Egg is to build a Guillotine on a table between the Saloon and Gunsmith Shop. You will need four items. These items can be collected and built in any order:

Wire and spool from Gunsmith shop near tunnel to Bank
Crystal inside Quick Revive Saloon Tunnel. It's just after the pitfall
Satellite on the second floor balcony of the Saloon
Antennae inside the Stables
Step 2: Charge Glass Orbs

For this step you will need the Paralyzer from the Mystery Box. When one player gets it, charge four Glass Orbs around the map until a chime sounds. The locations are:

Left of the Church's front door
Near the Saloon
In the tunnels near the Quick Revive room
At the back side of the Haunted Mansion
Step 3: Obtain and Fill the Lantern

After completing the last step, a lantern will fly around the map. Get it down by cooking a grenade so it explodes right next to the flying lantern. One of the players must then pick it up and fill it. To fill the lantern, you will need to kill a few Ghosts from the Haunted Mansion until Richtofen speak.

Step 4: Find and Decipher Code

With the lantern filled, you will need to place it on a glowing lantern symbol at the top of the Gunsmith Shop. Jump over from the Saloon's balcony to reach the rooftop with this symbol. A code of some sort will appear on the wall nearby that gives you a hint to the next step. This code will change between five available codes on each game. This code will give the names of three out of five signs around the map. These signs will have a name clearly written on them, so it'll be easier to know which to hit first. See the image below for the code and name of the sign.

[ Register or Signin to view external links. ]

You must hit all three in the order they are listed with the Galvaknuckles or Bowie Knife. Before you do this, make sure one player has obtained the Time Bomb from the Mystery Box.

Step 5: Follow the Soul

This step is tied in with the last one. You will need to hit all three signs to unleash some sort of energy. It may be a lost soul. Follow the soul around the map, touching it from time to time until it reaches the guillotine. Once it finally reaches it, you will need to charge the crystal. Allow zombies to walk near the guillotine; they will start to glow with the same light as the crystal. With them glowing, kill the zombies to fill the crystal. Do this until you hear more dialogue.

Step 6: Round Infinity

The next step is to obtain a Time Bomb from the Mystery Box. Have the player throw the Time Bomb onto the guillotine and detonate it to enter round infinity. Each of the four player's dead bodies will be laid out around the map. Look for them and search the bodies until you find a lever like the power switch. It may take your team more than one attempt to find it.

Step 7: Maze Levers

This step revolves around four colored levers on the doors in the Maze. You will need to use each lever in a specific order to complete the step. If you chose the right lever, a spark should come out. If not, exit the maze and try again. Try to remember which order the colors go. The colors will change each game, so we can't give you an exact order.

Step 8: Target Practice

The next step is to Make a Wish on the fountain. To do so, you will need the Prisoner to smash the fountain by giving him booze. An option to make a wish by holding the reload button on the fountain will appear. Now it's time for Target Practice.

Targets will appear around the Haunted Mansion, Courthouse / Confectionery area, Saloon, and Jailhouse. All four players must hit all these targets without missing one before it disappears. Overall accuracy doesn't matter, just make sure it gets hit. If all targets are hit, the achievement / trophy will unlock! All Perk-A-Colas that can be found on the map will be permanently unlocked, you will be able to hold four weapons at a time, and there will be a permanent Fire Sale.

Optional Step: Ending

Complete the Richtofen sides on all previous zombie maps to gain access to this ending. Interact with the button in a box at the back of the courthouse to see it. The game will not end, and no other achievements / trophies will unlock.
