Koop Paradise Killer - SteamParadise Killer - Steam

An island outside of reality. A rogue human civilization hoping to resurrect dead alien gods. A murder behind locked doors.

Paradise is an island that regenerates every few millennia. The psychic power that the alien worshipers within release into the universe is meant to feed and eventually resurrect their fallen deities. But this force also attracts undesired interest from demons, who eventually corrupt each island — until a new alternate reality is birthed by the Council.

The system isn’t perfect, but it will be one day — on Perfect 25, the next island-to-be. But on the eve of rebirth, the Council is murdered and Paradise is killed.

In the aftermath, the “investigation freak” Lady Love Dies is summoned from exile to find the culprit. This is the crime to end all crimes.

What are the facts? What are the truths? Are they the same?




Return to Paradise Island in this updated and enhanced version of Paradise Killer, featuring new music and new mysterious beings, additional quests and rewards, extra Starlight skins, and more collectibles to find, plus performance improvements, a HUDless mode and Steam achievements. A free update for all players, available March 16, 2022.


Featuring DX12 support, ray tracing* (DX12 only), advanced upscaling (NVidia DLSS and AMD SR), and a host of other visual and performance updates, Paradise Island looks more stunning than ever!




You are tasked with finding the killer and building an airtight case against them. Take your case to trial and argue your interpretation of the evidence. Only when someone is successfully convicted can the crime be considered solved and Paradise be saved.


The “truth” is that there are many possible killers, and many ways to build a case. Even if you make a convincing case for prosecution and get someone convicted, is the mystery really solved?


Paradise is an island set in an alternate future history filled with cryptic lore and even more mysteries. Examine bizarre relics to learn more about this world’s surreal history.


You choose who to accuse, and build a case to support conviction. Everyone on Paradise has a secret to hide and something to gain. Old friends become new suspects, forcing you to choose between the evidence, the greater good and your own beliefs. There are many possible murderers, but who you pick will define your own personal truth.


Let your personal computer and electronic assistant Starlight be your guide through another dance of an investigation. Collect evidence, record testimony and interpret the facts to form your own truth.

Solve hieroglyph puzzles on ancient nightmare computers to discover new areas of the island, find concealed evidence and reveal terrifying secrets.
