Half the clues each
You play Ally or Old Dog, usually stuck in separate rooms with different evidence. One of you finds the cipher, the other finds the key. One reads the password hint, the other types it in.
You spend most of the game describing what is in front of you over voice chat, then solving the bit on your partner's side. Redirect a water flow because they read you the valve order, solder a component while they talk you through the diagram, wake up a drunk because they found out how. It is slow, talky detective work, and the eureka moment lands when your two halves finally click.
More than eighty puzzles to trade
The case throws over 80 puzzles at you, from intricate locks and computer passwords to cryptic ciphers and electronic soldering. NPC conversations work the same way: each detective gets different answers, and some chats are puzzles you untangle together.
Nothing here is timed, so you can sit with a puzzle and reason it out. It gets properly difficult toward the end, and you will need clear, patient communication. Keep a shared notebook habit too: you can jot notes and sketch solutions right on the screen, which helps when the codes get long.
A noir case told in comic panels
The hunt for the Cryptic Killer turns personal when Ally and Old Dog become his targets. The story arrives in almost 100 pages of hand-drawn comic panels, all shadows and hardboiled angles.
Between investigation beats you get retro minigames with a co-op twist: darts, Three in a Row, Match Three, Claw Machine, Push and Pull. And yes, you can knock on your partner's window, poke them, or shake their screen just to hear them sigh. It keeps a tense kidnapping plot funny and light between friends.
Good to know before you team up?
Can you start here without playing the earlier games?
Yes. This is the second standalone chapter in the Cryptic Killer series, after Unboxing the Cryptic Killer. Playing that first gives you more background on Ally, Old Dog, and their nemesis, but you can follow and finish this case cold.
How long does the case take?
Longer than the earlier games. Expect several evenings at a relaxed pace, more if you hunt down the missable tokens that unlock extra puzzles in the bar, or replay in investigation mode. The back half is tougher, so plan for longer sessions there.
What do you actually do minute to minute?
Look, read, describe, and combine. You search your own room, read your own documents and dialogue, then talk your partner through what they need. Puzzles range from locks and passwords to water pipes, ciphers, soldering, and odd jobs like waking a drunk, broken up by short co-op arcade games.
