Blue Protocol: Star Resonance is a free-to-play action-combat MMORPG developed by Shanghai Bokura Network Technology and published by A Plus Japan. It launched worldwide on October 9, 2025 for PC via Steam and the Epic Games Store, Android, and iOS. The game serves as a follow-up to Bandai Namco’s Blue Protocol, the 2023 MMOMMO. Massively Multiplayer Online — a game that hosts very large numbers of players together in one shared, persistent world. that was discontinued prior to this release.
Gameplay & Combat Systems
Star Resonance is built around traditional party-based roles — DPS, tank, and healer — paired with action-combat mechanics that include real-time dodging and combo-driven encounters. The game also features open-world exploration, gathering, and social systems such as trading and guilds.
Monetization Structure
The game operates on a free-to-play model with microtransactions. It uses multiple in-game currencies, available in both “bound” (earned through gameplay) and “unbound” (purchased) forms. Gacha mechanics are present, covering cosmetic items like costumes and mounts, convenience items that accelerate progression, and items that grant combat abilities.
Development & Release Context
The project began as a mobile-only entry set in the Blue Protocol universe but was later expanded into a distinct cross-platform MMORPG. It was announced at Tokyo Game Show 2025 and produced by Chen Min. The Western release was confirmed for 2025 following the shutdown of Bandai Namco’s original Blue Protocol MMO. The worldwide launch on October 9, 2025 covered Microsoft Windows, iOS, and Android simultaneously across all regions.
