Note: If this is your first time playing, I highly recommend getting aquainted with the ship first. You should know how to navigate from the spawn to the engine room without much difficulty before attempting the full Easter Egg.
When you spawn, you will find yourself on the front end (bow/Forecastle) of the ship. Your first goal will be to unlock doors until you reach the other end (stern/Poop Deck). Once there, you will see a glowing object suspended above a catwalk. Climb onto the catwalk and interact with the Artifact to open additional areas of the ship and begin the Easter Egg.
Four terminals will appear across the ship.
You can determine the current location of the Pack-a-Punch by walking up to a terminal and reading the text that appears on screen. Each of the locations also correlates with an elemental symbol (see Clocks). Once learned, they can be used to determine the location from a distance. The active terminal's element will be lit up.
In the engine room, use the Kraken to shoot the four moving pistons in the center of the room. They will begin smoking and stop moving.
Above the pistons, there will be several red wheels with matching lights further above them (3 per piston, 12 total). Looking up at the lights, turn the wheels that have a flashing light. This light can be red or white. If a wheel does not turn right away, holding the interact key (F on PC) will work. You must turn each wheel so the handle-bar is facing away from the light. The bars below the non-flashing lights must be turned toward the light.
There should be six flashing lights. Once all six wheels have been turned, step into the Turbine Room and look to your right. Against the wall there will be a lever. Pull it to complete the upgrade.
The new Pack-a-Punch will spawn in all locations, cost 5000 points to upgrade, but will also refill the ammo of your weapon. This effect will last one round, after which the Pack-a-Punch will return to its normal rotation.
When you reach the engine room and cargo hold, they will be flooded. You can drain these areas easily by using a well-lit wall valve located somewhere under water.
Once the Pipes Easter Egg is completed, these sections will re-flood, but can be drained again using the same valves.
The outlets will spawn in 4 locations, chosen randomly from a pool of 6 possible locations. The outlet will always be present in the location, but will not always be "active." You will know an outlet is active because it will occasionally spew a certain element from the list above. See the Help section for more information.
For this next section, you will need a Kraken upgraded with the Acid element. See the Distillery section for more info.
Once you have the restored Artifact, you will need to go to the Turbine Room. There will be 9 blue pipes with one or two leaks in them. Initially, these leaks will be spewing steam only. But, once you hit them with an Acid Kraken, they will also begin leaking small droplets of water. After all nine have been hit, the room will re-flood.
Next, you will need to wait until the Pack-a-Punch is moved back into the turbine room. You will then be able to Pack-a-Punch the Artifact, completing this step of the Easter Egg.
Click and drag a planet between the two lists to keep track of their order. The planets are initially sorted in alphabetical order for convenience. The sun always comes last. Use the reset button above to reset the order.
