DEATH IN UNISON

About this game

Survive the world's deadliest psychopaths. Experience a unique 2 player co-op experience that puts your teamwork and communication to the test. Complete your duties alone or with a partner in a prison like no other.



Nestled in the Pacific Ocean lies the Corton Island Institute of Rehabilitation. Hidden from the public, the island prison harbors society's most notorious criminals, many wielding supernatural abilities.


Join forces with a companion to tackle the job together. Each person will find themselves in separated rooms and must rely only on communication through walkie talkies to complete duties together. No partner? The job can be done entirely solo as well!

Note: The co-op experience relies on the use of voice chat as a vital mechanic.




Take on the role of administration while alone in an office. Fulfill duties to meet your employer's expectations. Failure is not an option, where consequences are as unforgiving as the ocean that surrounds.


Each day, the prison experiences electrical outages. Defend yourself against a diverse range of convicts, all the while ensuring the execution of your duties.




Infiltrate prison network systems and solve puzzles to discover the truth behind how the prison came to be.

  DEATH IN UNISON | MINI PATCH 7

  What up peeps! Wanted to start off and say that the reception of the game has far exceeded my expectations. I am so super grateful to everyone who has played it. The success of this game has allowed me to pursue my game development career as a full time developer. I've got plenty more games and ideas that I want to make and provide to ya all, so stay tuned! But first, another lil update for DEATH IN UNISON. Notes below: ADMITTANCE had an issue where the grading with multiple crimes was taught in an unintuitive way. The duty will now only provide one type of crime to prevent confusion and misunderstanding. ACCESS training now shows on the intended day Fixed bug where dying to SACRA would cause some whacky stuff to happen Fixed bug where the keypad noise on the cooking screen would play twice. Fixed issue with navigating the files on the secure network. Fixed issue where roles could be swapped in SOLO. Reworded some descriptions for better clarity.

There is no new added content so don't let the large update size fool ya. This update should fix the (extremely) annoying bug where some players could not connect to their friend's co-op lobby. Extremely sorry to all who were experiencing this! I am so incredibly honored by the feedback of the game. I've got plenty more to do so I hope you continue to stick around!
