Indie publisher First Break Labs and developer Underwater Fire Games have announced that their upcoming atmospheric puzzle title Particle Hearts will release on 25 August 2025 for PC via Steam, Nintendo Switch, Xbox, and PlayStation 5.
Set in a mysterious world built entirely from particles, Particle Hearts invites players to uncover their role in a strange and visually striking environment. Using a range of special abilities, players will manipulate particles to solve intricate puzzles, sneak past threats, and access hidden paths as they explore a land where nothing is quite as it seems.
The game seeks to place an emphasis on open-ended exploration and non-linear progression, allowing players to chart their own path through each particle-rich biome. Along the way, they’ll meet strange creatures and uncover fragments of a narrative where the lines between ally and enemy are deliberately blurred.
Promoted features of the game include:
- Unlock and master a variety of abilities that let you interact with the world’s particles in creative ways
- Use your skills to bypass hazards, unlock secrets, and solve environmental puzzles
- Navigate open-ended environments with freedom of movement and exploration
- Engage with a mysterious storyline filled with moral ambiguity and hidden truths
