Heaven Burns Red

Humanity survives in underground bunkers after an alien invasion known as The Unseen wipes out most of the surface. Players command the 7th Melody, a specialized unit of young women piloting bio-mechanical units called Prototypes to fight back against these threats. This free-to-play title blends grid-based tactical movement with real-time action sequences that require precise timing to trigger Break states and stun enemies.

The narrative stands apart from typical gacha games by prioritizing a deep, emotional story written by Jun Maeda. The main plot spans approximately 30 hours and concludes its initial arc in August 2026. While combat involves strategic positioning and skill management, the game also includes a dedicated story mode for players who wish to experience the script without engaging in battles. [edit]

Battles take place on hexagonal grids where players must position their squad members to maximize damage output while avoiding enemy attacks. Once a command is issued, characters execute actions in real time, meaning players cannot pause to adjust tactics mid-attack. Success relies on breaking enemy defenses through well-timed strikes to trigger stuns, followed by powerful follow-up combos.

The system features unique skills for each character with specific elemental affinities and cooldown periods. Players collect new units and weapons using an in-game currency called Shards, which are obtained through gameplay or microtransactions. The design emphasizes individual progression rather than competitive multiplayer modes like PvP or co-op raids. [edit]

The 7th Melody operates out of Sanctuary 7, a massive underground facility housing the last remnants of humanity. Their mission involves patrolling the surface to locate and eliminate The Unseen before they can breach the sanctuaries. The narrative explores heavy themes of sacrifice and what it means to remain human when faced with extinction.

Character interactions often feature romantic subtext and explicit relationships between female soldiers, a hallmark of the series' writing style. The story concluded its primary chapter updates in late 2026, coinciding with the announcement that lead writer Jun Maeda had entered palliative care for pharyngeal cancer. Despite his health decline, the team released the final story chapters and a major collaboration event with Persona 5 Royal later that year. [edit]
