Unsolved Case Walkthrough: How to Solve the Co-op Investigation

Unsolved Case is a cooperative point-and-click puzzle adventure featuring detectives Old Dog and Ally. The investigation follows the return of the Cryptic Killer and a mysterious locked box delivered to the detectives.

This walkthrough explains how to approach the investigation, share clues, and use the game’s built-in hints when a puzzle becomes difficult.

Step 1: Prepare Both Players

Unsolved Case requires two players using separate devices. Each player receives different information, so both screens are important to the investigation.

Before starting, make sure both players have the game installed and can communicate through an external voice application. The game does not provide built-in voice chat.

Step 2: Start the Co-op Investigation

Both players should select Play Co-op from the main menu. One player creates the session, while the second joins using the invitation code.

Follow the introductory instructions before continuing. Make sure both players are connected and ready to exchange information.

Step 3: Investigate Both Screens

Each detective sees different objects and clues. Do not assume that your partner has the same information displayed on their device.

• Describe every important object you can see.
• Read visible numbers and symbols aloud.
• Compare information from both locations.
• Write down codes and observations in the notebook.
• Ask your partner to confirm unclear details.

The notebook and drawing features can help organize clues. Use them to record information that may be needed later.

Step 4: Solve the Locked Box Challenges

The mysterious box is a central part of the investigation. Its contents are protected by codes and collaborative puzzles.

Work together to identify the information needed for each challenge. The official game description also mentions equipment rewiring, CCTV hacking, and drawing-based puzzles.

Some challenges require information from both players. Compare your observations before entering a code or making a decision.

Step 5: Use Hints When Necessary

If you become stuck, open the puzzle close-up and select Hint in the upper-right corner.

The first hints provide guidance without immediately revealing the answer. The final hint usually shows the solution.

Before using a hint, discuss the puzzle with your partner. The missing clue may already be visible on the other screen.

Step 6: Complete the Investigation

Continue solving the cooperative challenges until the case reaches its conclusion. Unsolved Case is a complete prequel, although its story ends on a cliffhanger connected to the next game, Unboxing the Cryptic Killer.
