About DEATH IN UNISON
Death in Unison places you on Corton Island Institute of Rehabilitation, a hidden prison in the Pacific Ocean that contains society’s most dangerous criminals, many with supernatural abilities. You must survive the environment while completing demanding administrative duties.
The game offers a two‑player co‑op mode where each participant is isolated in separate rooms and must rely on walkie‑talkie voice chat, as well as a solo mode where a single administrator handles the same tasks alone.
01 / THE GUIDE
Co‑op Communication
In two‑player mode each player occupies a different room, and the only method of coordination is voice chat through walkie‑talkies. The description calls this communication a vital mechanic, meaning it is required for progress.
Because visual information is limited, success depends on clear spoken instructions and careful listening. Players must describe their actions and surroundings so that both can act in sync.
- Speak slowly and confirm each step before acting.
- Agree on short code words for recurring tasks.
02 / THE GUIDE
Solo Administration
When playing alone you assume the role of an administrator working from a solitary office. The description states you must fulfill duties to meet your employer’s expectations, indicating that duties must be fulfilled.
All puzzle solving, network infiltration, and defensive actions are performed without a partner, while fulfilling duties to meet your employer’s expectations.
- Create a simple checklist of duties before each session.
- Pause briefly after major actions to reassess the environment.

03 / THE GUIDE
Electrical Outages
Each in‑game day the prison experiences electrical outages, as explicitly noted in the description. During these periods the player must continue to defend against convicts and complete duties.
The outages are presented as a recurring condition, so players should be prepared to act while power is unavailable, without assuming any specific changes to combat or puzzles beyond what is stated.
- Plan tasks that can be done without reliance on powered equipment.
- Keep a mental note of which actions you can perform during an outage.
04 / THE GUIDE
Convict Threats
The island houses notorious criminals, many wielding supernatural abilities. The description says you must defend yourself against a diverse range of convicts while completing duties.
These encounters are part of the core challenge, requiring the player to balance combat with administrative responsibilities regardless of whether they play solo or in co‑op.
- Observe a convict’s behavior before engaging directly.
- Use environmental cover when possible to reduce exposure.
05 / THE GUIDE
Network Puzzles
Players must infiltrate the prison’s network systems and solve puzzles to uncover the institute’s origin. The description links puzzle solving directly to discovering the truth behind the prison.
Solving these puzzles is tied to uncovering the truth behind the prison, as the description links puzzle solving directly to that discovery.
- Write down any code fragments or clues you encounter.
- Cross‑reference puzzle hints with environmental details for context.
