The following videos show how you go about obtaining the Ritual item's and where to do the Rituals.

As a side note it is best to not shoot the Keeper's within the Ritual since they do not give any points and upon completion of a Ritual every Player inside receives 500 points.

Ritual 1










Ritual 2










Ritual 3










Ritual 4










Pack-a-Punch Ritual










In the following video it show's you where the symbols are to open the wall and obtain the Egg and then where each Soul Box is for the Egg.










Once each Soul Box has been complete you will return the Egg and retrieve the Sword.










Here's a useful guide to quickly note down what symbols you get.


After obtaining your Sword you need to go obtain the Arch-Ovum, to do so you need to go to your Characters respective place as the following.

Magician - Nero's Ritual Site
Boxer - Waterfront Boxing Ring
Girl - The Black Lace
Detective - Ruby Rabbit










After receiving the Arch-Ovum you must go to and activate the following 4 Circles in each district. Each person in the game can only activate one Circle per round meaning the Sword Upgrade process will take 4 rounds total. Using the Sword to take out the Margwa Eye's can be very effective but you need to watch out for its Slam attack.



Once you activate one of these Circles it will appear as such, and two Margwa's will spawn and only attack the player that activated the Circle.










Once all 4 have been complete return back to where you obtained your Arch-Ovum and give the Keeper it back and then you can receive the Upgraded Sword.


Firstly you need to walk into Nero's Ritual Site and to the left of the entrance in front of the bookshelf you need to pick up this book.










Now coming down into the Rift there will be a flag opposite of the Gobble Gum machine, for the following step the Sword along with the Apothicon Servant are extremely useful here. I would also very very strongly suggest have one player bring in Round Robbin Gobblegum and another Fear In Headlights Gobblegum to greatly speed this step up and make it easy.










After obtaining this Flag you need to go to the Electrical Discs on the floor in various areas and then defend them from all damage for a period of time, killing the Shadowman will progress the flag more than defending it. After the flag illuminates purple and a ding audio cue sounds pick up the flag and go to another electrical disc. After this is done twice go to a rituals site and go next to the Keeper. It will automatically be placed and after its done transferring the energy the Keeper will no longer be a ghost and will teleport to the Pack-a-punch area. You must do this for all 4 ritual sites.


After you finish the Flag Charging all players need to go to the Pack-a-punch area then have all 4 players place their Sword in the Keeper Pedestals the same ones you originally put the Gateworms in. Once the fourth sword has been placed the keepers will rise and position themselves.
The keepers will now beam a beam at the Shadowman destroying his protective bubble. Shoot the Shadowman until he reaches the summoning table (Where you started the pack-a-punch ritual).


Keep in mind the Shadowman moves every time he is shot so watch out when you shoot him. If you are facing the Pack-a-punch he will be Middle, Left, Right then Middle the rest of the shots.
After the Shadowman has been taken in by the summoning key, the rift door block will be lifted and you can progress to the next step.












Now purple Margwa's will spawn. Killing these Margwa's will reactivate the beast mode altars. Using these altars will allow for an infinite beast mode (Provided you are not hit by the Margwa's or stand in the purple auras).

When you are in the beast mode three people will need to go to each of the tram locations and one needs to be in the middle. Firstly, the easiest spot to do the middle. The player in the middle can coordinate the others on what to do however this is not necessary. This person will zap the three keepers AFTER the Gateworm has been crushed, this spot in the image is in my opinion the best spot to stand.










Now for the people at the tram stations. They (or you) must zap the small power box in the corner or middle of the station. More accurately, look at the doors to where you would enter the tram. The box will be in the middle of the two doors or in one of the corners of that wall. When the tram has been called IN HUMAN FORM, quickly get back into beast mode and rush to zap the power box until the railway above glows a light blue. These are what the boxes look like they will differ positions for each tram station.











When the railway has been zapped for all three sides (This can be noticed by the player in the middle when all three sides and the intersection of the railway are glowing light blue and the worm has been crushed by the tram, zap the three keepers in the middle and the cutscene will start to play.

Here's a video version of the Shadows Of Evil Easter Egg.

The following images show the Shield Part locations. (As a note there are multiple shield part spawn location on each "Electric Door" area these images showcase one, in your game they may differ between different nearby locations).

Waterfront










Canal










Footlight










The following images show the general location of Fuse spawn locations along with the Fuse Box in the Rift. (As a note there are multiple fuse spawn location on each "Bridge" area these images showcase one, in your game they may differ between different nearby locations).

Waterfront










Canal










Footlight










Here is my video showcasing how to go about getting the Fuse's required and where to put them to unlock the Civil Protector, it should also be noted after the Main Easter Egg the Civil Protector will get an upgrade including a Golden reskin and a Pack-a-punched weapon.

The Apothicon Servant consists of three parts: Margwa Tentacle (Found randomly by harvesting grown, purple pods). Margwa Heart (Found by killing the first Margwa that appears). Xenomatter (Dropped by Parasites or Meatballs only after round 12). After retrieving all materials you can craft the Apothicon Servant.

The following videos will showcase each beast mode skip to see the symbol's without using the tram.

Waterfront










Canal










Footlight











To get an easy free 500 points and basically just refund buying the first door once you spawn in buy the door then to the right there will be Chang's Laundry, just simply look in at the coat with the paper and throw a grenade at it and if you hit it then you can then interact with the paper on the box to your right as shown in this video.



Cream Cake Trip Mine's can be gained by damaging the Devil-O-Donuts Food Carts with the trip mine thrown next to it when a zombie walks past and detonates it. It will turn the trip mine into a Cream Cake Mine, spreading some cakes upon detonation. Cart locations are as the following.

In the Junction, near the Gobblegum machine.
In the Canals, near the Gobblegum machine.
In the Footlight district, on the corner where the fuse can spawn.
In the Waterfront district, on the same level as the lower box towards the rift.

Donuts Trip Mine: Gained by damaging the Cream Cake Food Carts with the trip mine thrown next to it when a zombie walks past and detonates it. It will turn the trip mine into a Donut Mine, spreading some Donuts upon detonation. Cart locations are as the following.

In the Junction, near Stamin-up.
In the Canals, in front of the buyable door towards the Ruby Rabbit.
In the Footlight district, in front of the Perk-a-Cola machine.

Here's an image of what these carts look like.

In my opinion this is NOT worth it. After the shield breaks you cannot upgrade or get the upgraded version anymore. Anyways the way to upgrade the shield is to line up 10 zombies and rocket boost into them when you successfully do this it will make a bowling sound queue to let you know you did it properly, you must repeat this 12 times in a row without missing once if you do then you need to restart. The best way to do this is to get 3 in a row then let a zombie break your shield I also suggest using a widows wine grenade on the group of zombies before dashing directly through them. This will reward you with 4 rocket boosts on your shield instead of 3 and increase the durability.

There are three teleporters around the map located to the left, right, and front of the spawning area throughout the door's. After activating every teleporter will open Pack-a-punch, then from Pack-a-punch go through the left door and you will see a barricade. Then you will aim for the Fly Trap with a Pack-a-punched weapon and shoot, then after green orbs will go up in the sky if you've done it correctly.


Three items will now be found across the map in the following locations. One is in a furnace just in front of the 2nd teleporter (Left of the 1st). The second one is located on the fire escape outside the map next to the power switch, and the final one is located in a water cooling vat in the 3rd teleporter room (Right of the 1st).

Next go to the furnace shown below (second door to the right of the 1st teleporter). It is opposite of a perk machine and mystery box location. Once here, find the open door side and pick up the Annihilator from the furnace.










Here's a video version of The Giant Easter Egg.

Dragon head locations are as the following in the images below. As a note each head will take a total of 8 zombies to feed, one to activate 7 to fill.

East Side Castle










Church










Catacombs Pyramid










After you feed all 3 of the dragons head down the stairs to the left of Speed Cola to the Catacombs and pick up the Wrath of The Ancient's Bow. After you do this (On Ranked Mode) you need to get one upgraded bow per player, if you are not on Ranked mode then you need to get all 4 bows for the later steps. You do only need one though to start the Wisp step although its ideal to have in a 4 player lobby at least 3 bows.

After upgrading the Wrath of the Ancients to one of the previous 4 bows, you can now shoot the teleporters electrical orbs with the Wrath of the Ancients to make them glow orange. After shooting these orbs a sound cue will start it sounds like a growl and the orbs should lose their orange glow. You will now have to look around the map for one of the eight wisps that will have lightning around them. You will shoot 4 of these to enable the teleporter to glow Purple so you can travel to the past. The wisp locations are shown below. I heavily advise you have 3 players stand at each different area walking between the locations shown below. Ex. player 1 rotating between the 3 church spots and same goes for two other players.

Church

East Side Castle

Spawn Area

Once entering The Past you will turn left and pick up the Blue Canister on the ground then to the right to pick up the Fuses and then back to the safe to get the 3 digit code below is a cheat sheet for remembering the code easier.


After coming back you will need to go to the death ray and insert the fuse into the central machine and go to the other side and then switch it to Protect mode, then head over to the terminal and you will need to input the Code from the Safe from The Past. after doing so return downstairs to the teleporter and retrieve the items within the safe. After so return to the death ray and switch it back to Destroy and insert the Fuses from the safe into the pillar with the missing fuse.

Now head back to the Terminal and interact with the center of the terminal and remember the positions of each symbol then the screen will flash with a symbol and you will interact with the smaller blank screen with what the symbol is that was there prior Ex. If the circle is far right then the screens go black and the big screen shows the circle then you interact with the far right monitor. You will do this for the terminal outside Clock Tower and then the one in the Rocket Test Site near Pack-a-punch.

After doing this each Ball on the Death Ray will be glowing white then you will head to the back of the Machine and press the green Button then you will see Dempsey's Cryo Pod coming down from the sky.

Going over to Dempsey's pod you will notice an Artifact on the ground as shown below you will pick this up then you must do the Wisps again to go back in time and this time you will go to the right and interact with a Book and then go to the middle of the room and there will be a box with a Stone Slab, after this step go to the Knight's Grave next to the Wrath Of The Ancient's Bow and interact with the small hole inserting the Vrill Artifact into it to summon the Keeper.

Now you will need to follow the Keeper for a total of 4 soul boxes, it will lead you to 4 different areas and then you need to stand inside the small circle and it will glow on the edges of your screen the color of the bow you need to use. Purple being Void, Red being the Fire bow, and going on for 4 total. The more players you have within the circle the bigger it gets so you should have everyone in it. Now after this the Keeper will go to the Pyramid and then it will rise up and you will insert the Blue Canister into the missing slot.
Now you will have each player stand on each of the Gravitation Plates and deploy the Ragnarok at the same time to teleport you to the Boss Fight. Make sure you are fully ready because there is no going back.










Now the keeper will go through it's attack phases and Panzers will spawn and everything so you must survive and wait until you see an Electrical Ball under the keeper then someone needs to rush over and place the Ragnarok in it and then the Keeper will slowly come down and then you will see its Chest turn Yellow and then you open fire on the Yellow spot. You will need to do this a total of 4 times successfully you will know when you do it when the keeper spins in circles after you do this step. After all of this Congrats! you will now leave the fight and move onto the final step.

Now you will go to the Pyramid and pick up the Summoning Key, after this return to the Terminal next to the Clock Tower and interact with it. Doing this will blow up the Moon and then shortly after start the Cutscene. Congrats you finished the Easter Egg.

Here's a video version of The Der Eisendrache Easter Egg.

Head to the Death Ray area and you will see a tower with a little Dragon on it, shoot this with your Wrath Of The Ancient's Bow. It will then open up revealing the Broken Arrow.

Now that you have the arrow you must go to 3 different spots and light some bonfires the following are shown in the images below.

Outside Clock Tower










Right Of The KRM Wallbuy










Rocket Test Site










Now you will fill the following 3 Soulboxes shown in the video's below then re shoot the bonfires with the electrified arrow's.

Outside Clock Tower










East Side Castle Above Gate Trap










Rocket Test Site










Now return to the original tower with the Dragon on top of it and interact with the blue cloudy smoke and then wait for your repaired arrow to come down.










Now return to the Lightning Bow Box and place the arrow inside then kill zombie's within the Pyramid area once finished interact with the box and the Lightning Bow will come out.










Firstly you will need to go around the map interacting with the following paintings in the following order to obtain the arrow.

Corridor Near Samantha's Bedroom










Downstairs From The Courtyard










Clock Tower










Church










Now head downstairs to the Pyramid and you will see a Wolf Symbol on the wall, when walking up to it then it will fall apart giving you the broken arrow.

Now you will have to head to the Rocket Test Site and as soon as you leave the big Circular door turn right and you will see up on the hill a Flag, you will now shoot this Flag with your bow and then down will fall a wolfs skull, pick this up. Return this skull to the Wolf Bow Soulbox in the Pyramid room by interacting with the Box and a Wolf will be summoned.










Now you will follow this summoned wolf around the map and it will begin to dig up areas, these are Soulboxes, now you will kill zombies until the dog digs up some Bones. Once you pick up 3 bones return to the Pyramid room, there will be a tomb across from the Pack-a-punch machine and once Anti-Gravity is enabled then you will shoot the Wolf Symbol above the tomb and then a platform will build itself, once this is complete wall run up on-top of it and interact with the coffin to build the skeleton. This skeleton will hold the Repaired Arrow.

Now return to the Wolf Bow Box and place the arrow inside then kill zombie's within the Pyramid area once finished interact with the box and the Wolf Bow will come out.

Head over to the Double Tap machine where the Gate Trap is located and between the gates look up and shoot the Void Symbol.

In order to get a free Mega Gobblegum you must go to the Teleporter room and pick up the little pot to the right after entering the doorway, then after this when you return to the past in the main Easter Egg you will place the pot in the same spot and once you come back it will be fully grown, interacting with the grown plant will reward you with a free Mega Gobblegum.












To get better Gondola items you must throw all your grenades inside the Gondola before it leaves in the beginning of the game. After this you must insert a total of 5 fuses throughout the game and the 5th one will bring up the 2nd Gondola with much better powerups and a chance for Monkey Bombs and other good items.

To turn on the power you must go underground just follow the symbols leading to power and then once you are down there enable the multiple switches they are both in the room with the 2 large Wooden Wheel's.

Now that you have power on there are 4 statues around the map you will need to have a player stand on each pressure plate near the statue at the same time to activate Pack-a-punch they are as the following.

Middle Spawn

Left Side Of Quick Revive Going To Power

On The Hill From The Bridge

Between Power Switches

In the main spawn room there are 4 circular buttons, each player will need to press one of these at the same time to activate the Eclipse. you will need to do the 3rd and 4th step within 3-5 minutes because the eclipse will end.

Go to the left side of quick revive near where you go down for power and before the entrance there is a statue to the right, you will need to interact with the circular button on this statue and it will begin talking.

Now 12 stone square slabs will have been spawned on either side of the spawn room. So now you will have everyone off the panels and have one person say the "Panel Finder" stand on a panel and check the symbol and then describe it to the "Panel Caller". now the "Panel Caller" will stand on the same symbol on the opposite side and then the "Panel Finder" will stand on the same symbol on their side, then they will both sink into the ground. Do this until all 12 on each side have sunk down then the Eclipse will end and there will be dialog at the statue again.

Now you will re enter Eclipse and have 3 players go down the waterslide and stand on the grate where you exit it at then the 4th player will come down a few seconds after while holding the interact button to flip a lever, after this is complete then you will get kicked out of Eclipse mode.
