To complete the Main Easter Egg for Shaolin Shuffle, simply follow the steps below exactly!

    Speak with Pam Grier.

    Using the Shuriken in one of the rat cages found around the map with a rat in it will unleash a rat that will lead you to all of the rat cages around the map - 1 at a time, you have to follow the rat to each cage around the map & then once you reach the final cage.. a little star will appear that you pick up and a LARGE YELLOW CIRCLE will appear on the ground! Kill zombies inside the circle and Ninjas will spawn. Kill the ninjas and a key will spawn where the circle was.

    Bring the key to the lockers in the subway near Bang Bangs and it will open a locker with symbols inside saying SOULKEY.

    Go around the map and shoot the symbols around the map in order.
        Outside Spawn to the right of the Dojo

        Near lion statue next to Deadeye Dewdrops
        Next to 3

    Go and find circle in front of the Black Cat Dojo, then fight rat king. He will drop an eye. Take that eye.

    Talk to Pam. You need to find 6 orange Rat King symbols around the map. You press L1 to use the eye to reveal a symbol near you. Shoot the symbol when you see it. Only 1 symbol spawns at a time. These can spawn in any order
        In the dojo above the door
        In the window of a Barber shop next to the dojo
        In the spawn area behind the train
        Behind a speaker in the Heebie Geebies
        On a water tower at the roof of the Inferno Disco
        In a window on the roof near the dojo
        On a clothes line near the Magic Wheel near Deadeye Dewdrops
        Ontop of an air duct in the Inferno Disco

        Behind Bombstoppers on a police car
        In the left corner in the blue room near Trail Blazers (You need to jump to see it)
        On the Inferno Disco sign across from the Theater
        Behind the stairs on the side of the Bang Bangs. Requires you to jump a bit

    After collecting 6 symbols a phone will start ringing. It will play a morse code message. Go around the map and find the Nightmare Summer poster with the number your morse code translates to on it. Every 5 beeps is a number (Short beep = .) (Long beep = -). Use this site to translate your beeps into numbers: http://rumkin.com/tools/cipher/morse.php

    Easy Morse Code Cheat Sheet

    Take the Nightmare Summer poster up to the roof of Inferno. You need to place this poster onto the spot-light. An X will spawn on a window and you will need to use explosives on it. After that you are required to kill some Ninja Zombies. This will cause some symbols to appear in the area. You need to shoot these symbols to spell out a word from the following list.

    After doing this, go to the RPR Evo wall-buy near Deadeye Dewdrops. There will be an option to start another boss fight with the Rat-King. Kill him, and pick up his brain.

    Talk to Pam. After 3 rounds the game will skip ahead 3 rounds and lock you in the Dojo area. Fire will block off all of the exits. Surviving this will drop the turnstile gate piece in front of the Dojo.

    Bring the turnstile piece to the broken turnstile gate in the spawn subway. You must interact with it to place it on the turnstile.

    Go to the alleyway near Mule Munchies and climb a wooden ladder. then shoot the symbol in this window

    Glowing Yellow circles will appear around the map kill zombies inside them until you hear a gong.

    Head to the Disco and hold Square on the DJ booth. A dancing Zombie will spawn on the dance floor in the Disco Inferno with a glowing Disco Ball above its head. You must group up normal Zombies and bring them on to the dance floor, only killing the Zombie with the Disco Ball above its head. The Disco Ball will transfer from Zombie to Zombie everytime you kill, you must repeat this multiple times until the Disco Zombie no longer spawns.

    A Rat King Symbol will now spawn outside of the Disco Inferno, activate it and fight the Rat King for a third time, rewarding you with his heart.

    Speak to Pam in the Blackcat Dojo. After this once you enter the Rat King's lair at any moment the boss fight will start and you will be locked inside.

    When you spawn in the Boss Fight you will be greeted by the Rat King and Zombies, the first step is to damage the Rat King as much as possible until he retreats. Afterward there are 3 tiers to the Boss Fight, you can choose which ones you begin and in what order. In the Boss Fight you will have Unlimited Revives on Solo thanks to Pam. Also, using your Chi Fighting Style you can smash the wooden crates around the edges of the arena, revealing Perk spawns that will indefinitely respawn throughout the Boss Fight.
        Eye: Scan the room using the Rat King's Eye, the Eye will be begin to rapidly bounce around the arena, revealing symbols on the ceiling, you must shoot all of these symbols to complete this tier.
        Heart: Hold activate in the center of the Arena on the Rat King Logo. Deadly Acid will be dumped around the perimeter of the arena by Willard Wyler, getting a kill on this acid will cleanse that section for a short period of time, the goal is to clear the entire perimeter of acid.
        Brain: Walk around the arena until the zombies destroy the Rat King's brain
