# Scarlet Tide: Closed Beta in China — Everything You Need to Know
> Scarlet Tide: ZeroERA, YoMio's 2.5D turn-based RPG mixing sandbox exploration and tactical battles, opens closed beta recruitment in mainland China in August 2025 on Android and iOS.
## [Scarlet Tide](https://after-strategy.com/en/jeux/scarlet-tide-zeroera/): The Closed Beta Arrives in China
- **Closed beta recruitment** opened in mainland China in August 2025, on Android and iOS.
- **2.5D turn-based RPG** mixing sandbox exploration and tactical battles.
- **A post-apocalyptic world** where the Scarlet Tide phenomenon froze humanity in eternal youth.
- **Gacha character collection** with young male heroes for turn-based combat.
- **Pre-registration open** on the official site yomio.cn ahead of the 2025 release window.
### Introduction
Scarlet Tide: ZeroERA is YoMio's upcoming 2.5D turn-based RPG, blending sandbox exploration with tactical battles and gacha character collection. The Chinese studio first revealed the game in November 2024, targeting a 2025 release on Android, iOS and Steam. In August 2025, YoMio opened recruitment for a closed beta test in mainland China. Here is what the announcement confirms and what to expect from the test.
### A world frozen in eternal youth
The story takes place in a post-apocalyptic world reshaped by the Scarlet Tide, a planetary phenomenon that emerged as Earth's response to environmental destruction. The phenomenon halted human growth in adolescence, leaving a society of children as the last survivors. You play as Zero, a frail boy raised on Atlas Island, who ventures beyond the ruins to uncover the secrets of the Scarlet Tide.
### Sandbox exploration and tactical battles
Gameplay blends sandbox exploration with tactical, turn-based battles. You roam a 2.5D world, gather resources, team up with young male characters and plan each fight on a horizontal battlefield. Characters are collected through gacha mechanics, so building a strong strategy means choosing which heroes to pull and upgrade.
In practice, the horizontal battlefield rewards positioning and timing: a well-placed team beats raw stats. The gacha pool rotates with each version, so saving currency for a favorite hero pays off.
### The closed beta in China
YoMio announced the closed beta test in August 2025, with recruitment open for players in mainland China on Android and iOS. The test gives selected players early access to the game before its official release, and the studio has already opened pre-registration on its official site, yomio.cn. No exact beta dates have been communicated yet, and the global release window remains 2025 or later.
### How to follow the beta
To take part on Android or iOS, watch YoMio's official channels: the game's website yomio.cn, its Bilibili account and the X account @ccZeroERA, which shared the recruitment news. The studio also announced that the game received its official license in China, a required step before launch. In practice, applying early through the official site for the current version is the safest way to secure a beta spot.
### Conclusion
Scarlet Tide: ZeroERA is still early, but the pieces are falling into place: a licensed title, open pre-registration and a first closed beta in China. The risk is a niche premise — a world where everyone stopped aging — that may not click with every player, but the gacha loop and tactical strategy give it identity. If you play turn-based RPGs on mobile, this beta is the first chance to test the current version. For players who follow gacha news, the August 2025 recruitment is the date to remember.
