How co-op works
Two online detectives use separate copies and screens, each receiving different objects, clues, and half of every location’s puzzle. Old Dog and Ally must describe what they see, compare notes, and relay codes or solutions that only become usable when both perspectives are combined.
About this game
Unsolved Case is a free-to-play detective puzzle game built around two-player online cooperation. A new lead reopens a cold case, and you and your partner must determine whether it's a trap or the work of a copycat. This prequel to the Cryptic Killer series is true co-op, not competitive, with both players working toward the same goal.

Each detective sees different parts of the crime scene and receives unique information. You'll decode ciphers, solve riddles, and compare evidence by talking through every detail. Progress depends on reading your screen carefully, sharing what you find, and listening to your partner's clues. The puzzles click into place only when both perspectives combine.
The game supports two-player online co-op with cross-platform play between Windows and Mac. Every session requires voice or text chat to succeed, creating an experience that feels like a real investigation conducted over a call. It's designed for duos who enjoy verbal puzzle-solving and detective work as a shared activity.

Frequently Asked Questions
Do both players need to own the game?
No, Unsolved Case is free-to-play, so both you and your partner can download it at no cost on Steam. It works on both Windows and Mac with cross-platform support.
How does the asymmetric information work?
Each player sees different parts of the crime scene and gets unique clues on their own screen. You have to constantly communicate what you're seeing because neither player has all the information needed to solve the puzzles alone.
Is this a competitive game or are we working together?
You're working together toward the same goal. This is true cooperative play, not competitive. Both detectives are on the same team trying to crack the case.
