sry for the large amount of color coding, especially in the Island and Ending parts 😅
Brief Introduction
“Terrible experiments are still ongoing on the island of betrayal. Will you be able
to escape the island?”
Island of Betrayal is a halloween event that takes place in an isolated island being run by
researchers who are performing mental experiments on humans. Experimental Subject units
have escaped the Mansion and are looking for a way to escape the island, while Researcher
units have been deployed to capture the escapists before they escape.
Teased already in the lobby screen before starting the game, Island of Betrayal serves as the
continuation to the Invitation to the Mansion event (Nightmares of the Mansion/Mansion 2022),
where it follows up the Exodus ending after escaping the Mansion. It has similar game
mechanics with the aforementioned event, where in 2 bad guys have to kill 6 good guys who
have to escape their current habitation.
Island of Betrayal also has a similar game play to Black Survival, where players are stuck on an
island, and they scavenge for resources. However, unlike Black Survival, players are split into
two roles: Researcher and Subject. Elaboration of these 2 roles at the Win Condition category
below.
The Island (needs confirmation on location items)
The Butterfly Island
The ‘Butterfly Island ’ is shaped like a Butterfly, with 6 locations in each wing. These locations
have different items and machines in them that can contribute to getting other items or
completing endings. These locations are split proportionally into two separate islands, and the
only things connecting them are the Tideland and the Cable Car vehicle.
From L-R, where in entity #, entity is the type of entity, # determines the level of object to
break/open/operate it, and the color determines what kind of tool or object you need/it is.

Win Condition
There are 2 roles : Subjects and Researchers.
Subject and Researcher Role Cards
The goal of the 6 Subjects is to escape the Mansion by any means, may it be through killing
other players to obtain their items, or working together to escape.
The goal of the 2 Researchers is to kill all the subjects that have escaped the Mansion. They
may use means such as gathering them together in the tides, separating them to kill one by
one, or using trickery to make subjects kill each other.
Researchers and Subjects can opt to work together and claim an easter egg ending, as it
results in victory for both parties as long as they fulfill the condition of the ending. However,
these endings require maximum cooperation and a lot of time, so unless you que with players
who are trustworthy and will help you, attempting easter egg endings will be hard.
Researchers spawn with one Level 1 Security Card and one Tracker each. They can use these
to access the Cable Car and Megaphone, or locate other players. Meanwhile, subjects spawn
with nothing.
Researchers can know who the other Researcher is by meeting them/encountering them. In
such case, the Researchers will see a red walkie-talkie icon on the other player, signalling the
fact that they are the second Researcher.

Gas Mask or cure it by using Antidotes.
