Halloween
The Halloween Event is a yearly event held from October 31st to November 6th. It was first added in 2021, and expanded on in 2022.
Like Talk Like a Pirate Day, Dr. Cubical will dress in a costume, appearing as a pumpkin, calling himself Dr. Pumpkical.
Halloween 2021
The first incarnation of the Halloween event was a simple quest board, with 9 total quests ranging from defeating a number of bosses in the Statue of Cubos to crafting a number of factory items, and completing all of them would award an Achievement and an Artifact.
As it was the first Halloween event, it was also very simple, and very easy to complete.
Halloween 2022
The second Halloween event in contrast, is much more complex. To even access it, you must be at least Military Tier 1. After that, clicking on the button that has appeared at the left-side of the screen, or the Ghost Ship near Shipyard, will take you to Halloween Island.
Halloween Island
Halloween Island is the main center of all things spooky. Dr. Pumpkical's spooky lair, the Spooky Tower, is where you will find the revamped quest system, along with upgrades needed to complete the event.
There are 3 main currencies: 
Pumpkins, 
Blood, and 
Souls. Each are used in their own section of the Spooky Tower to buy upgrades.
