If you want a game that actually puts conspiracy at the center of its story, start with Deus Ex, Paradise Killer, or The Painscreek Killings. They offer three very different kinds of investigation: an escalating sci-fi thriller shaped by player choices, an open-world murder case that asks you to build a prosecution, and a small-town cold case solved through observation and deduction.
The other five games below are worthwhile investigations, but their cited official descriptions establish mysteries or crime stories—not conspiracies. They’re included for players who want to piece together hidden truths, with that distinction made clear.

The games that explicitly involve a conspiracy
1. Deus Ex
In Deus Ex, you play JC Denton, a nano-augmented agent of the United Nations Anti-Terrorist Coalition. Eidos-Montréal’s official description frames the story as a conspiracy orchestrated by mysterious groups seeking world domination. It’s the most direct match here for a conspiracy thriller, with the plot’s scale growing as you investigate.
The investigation is tied to role-playing and problem-solving rather than one fixed approach. The official page highlights player choice, character interaction, action, and multiple solutions, so how you handle obstacles matters as much as what you uncover. The official listing identifies the game as available on PC. Eidos-Montréal: Deus Ex
#1 Best Overall
- New character: The game is a faithful but augmented adaptation of the original story, with a new character named Joanna Locke added to the mix. With her, you can regularly exit the train environment during playable flashbacks.
- Gameplay: Enter into Hercule Poirot’s head to discover mind maps and make deductions, adding an extra layer of depth to the gameplay. And don't forget the many puzzles with object manipulations that are scattered throughout each chapter.
- Plot: Get ready for major plot twists that will keep the players hooked until the very end. Murder on the Orient Express is renowned for having one of the best plot twists in literary history, and this game is no exception.
- Solve puzzles: As you play, you'll take on the roles of Poirot and Joanna, solve puzzles and make deductions to uncover the truth behind the murder. In a 3rd person view, you'll inspect the sets and talk to all the protagonists, searching for clues and confronting the suspects.
2. Paradise Killer
Paradise Killer begins with a mass murder: Lady Love Dies must investigate the deaths of the island’s ruling council. The official site describes it as a free-form, open-world, first-person investigation. You explore the island, collect clues with help from the Starlight assistant computer, and prepare arguments for a trial. The central question is whether you’ll find one culprit or expose a centuries-old conspiracy.
This is the strongest choice if you want to roam freely and decide how to assemble a case, rather than follow a tightly directed sequence of clues. Nintendo UK lists a digital Nintendo Switch version; that listing does not establish physical-cartridge availability. Official Paradise Killer site · Nintendo UK listing
Rank #2

3. The Painscreek Killings
In The Painscreek Killings, journalist Janet is sent to an abandoned town to investigate its killings and hidden secrets. Developer EQ Studios explicitly describes conspiracies among the truths she may expose, but this is a grounded murder investigation—not a globe-spanning secret-society thriller.

- Unassisted observation and clue connections: The Painscreek Killings.
- Reconstructing events from evidence or testimony: Return of the Obra Dinn or Her Story.
