FIRST SIGNAL | DEMO DISCOVERY · A Brazilian two-player detective game turns communication into its central puzzle. One investigator sees the physical file. The other works from a digital record. Neither has the whole picture.
Arquivo Cruzado — Last Access, from creator Thales Dias Silva, is designed for exactly two people using separate devices. Rather than asking a pair to stare at the same screen, it divides the evidence and asks them to describe, compare and question what they find. The premise makes the conversation between players part of the investigation.
One case, two perspectives
The free opening act presents two complementary interfaces: a physical case file for Investigator A and a digital file for Investigator B. The official demo describes the experience as a cooperative investigation in which each participant holds only part of the truth. It is an appealing twist on the familiar detective-game routine: a clue may be obvious to one player yet meaningless until the other supplies context.
That asymmetric setup is the game’s defining idea. It encourages players to explain details aloud, test theories together and notice inconsistencies rather than race through a shared checklist. Whether those exchanges sustain a full-length mystery is a question for a future hands-on assessment, not something we can establish from the submission alone.
Play the opening act in a browser
The official English-language demo is publicly presented as a free browser-based opening act, with no installation required. Its page identifies the experience as a two-player cooperative mystery. The developer says it can be used on desktop or mobile, with each investigator on a separate device. We verified the public demo page and its official description; this is discovery coverage, not a claim that we have played or completed the case.

And the complete case?
Thales has also provided an official Hotmart sales page for the paid full version. The developer explains that purchasers receive access instructions and that the complete case is not openly playable without purchase. The sales page is live, but we have not independently accessed or evaluated the paid game, so we are keeping this feature in First Signal rather than treating the full case as a tested Switchboard recommendation.
For anyone who enjoys cooperative puzzle solving and swapping theories with a friend, the free first act offers a way to see whether the two-file idea clicks. It is a mystery built around a simple social challenge: can two people reconstruct one truth without ever seeing exactly the same evidence?
