Is DUAL PROTOCOL: The Case of Eva & Miles worth it in 2026?
Mixed bag — reception is lukewarm: 58% of 153 Steam reviews are positive (player score 51/100). Most-praised strength: Co‑op mode shines. Current price: 6,89€ (25% off).
Verdict
Dual Protocol delivers a concise, cooperative mystery that works best in the company of friends, leveraging its puzzle design to keep sessions lively. Yet technical hiccups and shallow content prevent it from achieving broader acclaim, making it a niche but enjoyable experience for the right audience.
