Overview
890B is a top-down 3D adventure puzzle game developed by Nerd Games and published by Eastasiasoft. Set in a near future where severe pollution has made Earth uninhabitable, the game casts you as Noah, a scientist tasked with locating planet 890B, a world that matches Earth's specifications closely enough to sustain human life. The stakes are as high as they get, and the game leans into that weight with a stripped-back storytelling approach that lets player choices do most of the talking.
The setting is largely confined to a research lab environment, which keeps the scope tight and the atmosphere claustrophobic in the best way. Every room has a purpose, every item you pick up matters, and the puzzles are woven directly into the narrative rather than feeling like obstacles dropped in to pad runtime. For a game priced at $4.99, the ambition is real.

Gameplay and mechanics
At its core, 890B is built around exploration, item collection, and puzzle-solving from a top-down perspective. The key features that define the experience:

- Environmental puzzle-solving tied to story progression
- Item discovery and inventory management
- Branching choices that affect the ending
- Multiple endings based on player decisions
- Single-player, ESRB Mature rated for blood and violence
The puzzles themselves are not the brain-melting variety that sends players to walkthrough guides, but they carry enough logic and context to feel satisfying when solved. The real mechanical hook is the choice system. Decisions Noah makes throughout the lab don't just color the narrative, they determine whether humanity survives or doesn't. That's a meaningful amount of consequence for an indie game at this price point.
World and setting
890B's near-future Earth collapse premise is familiar territory for science fiction, but Nerd Games keeps the execution grounded. Rather than sprawling across multiple environments, the game focuses almost entirely on the research lab where Noah works, which gives the world a concentrated, pressurized feel. The minimalist visual style reinforces this. There's no visual noise competing for attention, just clean geometry and purposeful design that keeps the player focused on the story unfolding around them.

The storytelling is largely environmental and choice-driven rather than delivered through cutscenes or heavy dialogue. That approach means the narrative lands differently depending on how you play, which is a smart way to make a short game feel more personal.
Does 890B have multiple endings?
Yes. 890B features multiple endings determined by the choices Noah makes and the player's success or failure at key moments in the game. The branching structure means a single playthrough doesn't necessarily reveal everything, and the outcomes range from humanity finding a new home to a far bleaker result. For a puzzle adventure game at this length and price, the replayability built into those alternate endings gives the game more legs than it might otherwise have.

Content and replayability
890B is available on PlayStation, Xbox, Nintendo Switch, and PC via Steam, making it one of the more accessible indie puzzle games in its category. The game's short runtime is its most common criticism, but the multiple endings and the choice-heavy structure give players a reason to revisit. For anyone drawn to compact, narrative-driven puzzle adventures with genuine consequence baked into the mechanics, 890B delivers a focused experience that doesn't overstay its welcome.
