Evaluation

DUAL PROTOCOL: The Case of Eva & Miles launched on October 2, 2026 — one day before this assessment. The developer's launch announcement celebrated the release and thanked the community, but made no statements about post-launch content plans, DLC, or future updates. The pre-launch announcement on October 1, 2026 focused on wishlist milestones and a new Brazilian Portuguese localization, with no roadmap or content promises. There are no DLC listings on the store, no unreleased content entries, and no developer communication indicating what, if anything, comes after launch. The game is simply too new to draw any conclusions about its long-term content trajectory.

About this game

Track clues behind locked doors as Agent Eva, or manage the operation from analog terminals as Analyst Miles. One is in the heart of danger on the field; the other is at the desk, buried in data. You cannot see each other's screens, yet you must become each other's eyes and mind. Dual Protocol is a pure Noir asymmetric detective experience where your voice and the information you relay are your only weapons.

In this investigation, the only way forward is to keep talking. You must instantly describe every complex symbol, every mysterious object, and every lock you encounter to your partner. A single miscommunication or a missing detail in the halls of the Castellari Manor could lead to the case being closed forever.

The mysterious murder at the city’s most prestigious estate is too deep to be solved from a single perspective. As Eva, touch the physical evidence on the ground; as Miles, dive into the archives to decrypt technical blueprints. Eva finds the clues Miles cannot reach; Miles analyzes the complex data Eva cannot decipher.

A bleak universe where the technological texture of the 90s collides with classic noir atmosphere. Search for the truth amidst CRT flickers, heavy shadows, and the tactile clatter of vintage computers. Manually enter terminal commands, scan documents, and piece together the Castellari murder bit by bit.

Cross-Data Verification

Connect the dots by matching real-time field info with hidden central records.

Asymmetric Operation

One player physically triggers mechanisms in the manor while the other reads complex system manuals to guide the way.

Critical Deduction

When Miles's data and Eva's observations unite, the veil of mystery over the Castellari murder will finally lift.
