Which digital format of Dual Protocol: The Case of Eva & Miles should I buy for PC? An Account or a Steam Key ?

The account format is cheaper but has a more complicated activation process compared to a simple key or code. It may also cause access issues in the future, which is why we only recommend it to users who are familiar with this format or have used it before. If you’re looking for a simpler and safer activation process and don’t mind paying a bit more, we recommend buying the Steam Key format.

If I buy the account format of Dual Protocol: The Case of Eva & Miles, will the store provide all the activation instructions?

Yes, stores that sell this format usually guide users through the entire activation process, and if any issues arise, they offer customer support services. And if they don’t help, don’t worry—we’re here to assist you too.

Dual Protocol: The Case of Eva & Miles is an asymmetric noir puzzle game designed for two players who cannot see each other's screens. One player takes on the role of Agent Eva, investigating the Castellari murder from the field, tracking physical clues and navigating locked doors within a prestigious estate. The other becomes Analyst Miles, managing the operation from a desk surrounded by analog terminals and technical blueprints. Progress depends entirely on conversation—neither player can advance without the other's observations and insights.

The core gameplay loop revolves around real-time communication and information sharing. Eva discovers physical evidence and encounters complex mechanisms that only Miles can decipher from archived data and system manuals. Miles analyzes technical blueprints and encrypted information that Eva cannot access from the field. A single miscommunication or overlooked detail could close the case forever. Players must instantly describe symbols, mysterious objects, and lock mechanisms to guide their partner through the investigation.

The game's asymmetric design creates a unique puzzle-solving experience where complementary skill sets are essential. Eva's field observations combine with Miles's analytical capabilities to uncover the truth behind the Castellari murder. The noir atmosphere and minimalist visual style reinforce the detective narrative, while the conversation-only mechanic eliminates traditional gameplay barriers between partners.

Dual Protocol targets cooperative players seeking a communication-focused experience that rewards teamwork and clear information exchange. It appeals to fans of detective narratives, escape room puzzles, and games that prioritize dialogue and collaboration over action. The title works for both online and local co-op play, making it accessible to various gaming setups. Its design emphasizes the relationship between two characters working toward a shared goal, creating an intimate multiplayer experience.
