About the Game

Somewhere beneath the known world, a void is growing. Starfall: Elpis of the Abyss opens with a catastrophic event called a starfall, an occurrence that tears open a bottomless chasm and allows a creeping darkness to spill outward. Nobody fully understands what is driving the expansion of the abyss, though suspicions point toward a powerful and enigmatic figure whose motives remain deliberately unclear at the start. Stepping into this unstable world, you assume leadership of a makeshift expedition team assembled under desperate circumstances, and the story builds from that uneasy foundation.
The narrative is one of Starfall's most deliberate strengths. Rather than presenting a straightforward hero-versus-villain structure, the game complicates the relationship between the player character and the Great Demon King herself. She is described through a combination of power, beauty, and dread, and the story hints that understanding her true nature may matter as much as defeating her. Along the way the expedition gathers unexpected allies, including a character named Anneshi and a pink-haired girl who appears without warning, each bringing their own history and personality into the group dynamic. Choices made throughout the journey are framed as genuinely consequential, shaping how bonds develop and how the world responds.
Where Starfall distinguishes itself mechanically is through its semi-real-time combat system, which sits between the deliberate pace of turn-based strategy and the constant pressure of fully real-time action. Key features of the battle system include:
Pre-battle preparation: party composition, skill loadouts, and resource management all feed into readiness before the first enemy appears
Real-time command input: once a fight begins, issuing orders demands quick thinking and situational awareness
All-out attack command: a high-impact directive that rallies the entire party and can shift the momentum of a difficult encounter
Four profession classes: each profession contributes differently to overall damage output and team synergy, rewarding players who build varied rosters
Up to eight companions per battle: coordinating a large party amplifies both strategic depth and the stakes of each decision
Beyond combat, the expedition's daily rhythm includes a surprisingly grounding detail: Monica, the team's chef, prepares home-cooked meals four times a day. This is framed not as a minor side feature but as a genuine survival necessity, with the game suggesting that maintaining mental clarity requires nourishment just as much as strength or equipment. It is a small narrative choice that gives the expedition a lived-in quality absent from many RPGs.
Character growth is handled through a gacha collection system where new companions are recruited and then developed over time. The roster expands with repeated play, and the investment in leveling specific characters pays off in battle scenarios that punish underprepared teams. The voice cast adds considerable personality to each companion, with performances from recognized names lending emotional texture to story moments that might otherwise feel routine.
The musical direction reinforces the sense of scale throughout. Composer Go Shiina, known for work on other high-profile game soundtracks, contributes a theme that anchors the emotional tone, while BGM composition and arrangement from ACE supports the range of environments and moods encountered across the journey.
