The Blind Descent playtest allows players to experience developer Pokuch's subterranean Martian survival adventure ahead of its scheduled Early Access launch on December 2, 2026. Available on PC via Steam, testing sessions let explorers venture into subsurface alien biomes either solo or in four-player cooperative teams. Participants can access between two and five hours of survival gameplay while evaluating core systems, reporting technical bugs, and guiding development.
How to Sign Up for the Blind Descent Playtest
Access to testing builds is managed directly through Steam's built-in playtest feature. Players do not need external keys or third-party launchers to request entry.
- Navigate to the official Blind Descent store page on Steam.
- Log into your Steam account.
- Locate the playtest registration section beneath the purchase and wishlist buttons.
- Click the button labeled "Request Access" or "Apply for playtest."
- Check your Steam library or notification email to see when access is granted and begin the download.
Previous test sessions have occasionally distributed invite links allowing invited players to grant access to up to three friends, though availability depends on the specific testing phase.
Gameplay Length and Save Data Policies
Testing sessions provide a self-contained slice of Martian exploration. A typical run lasts roughly 2 to 5 hours, with the co-op testing build averaging around 4 hours depending on pacing, survival caution, and exploration depth.
Testing windows are temporary periods typically scheduled to run for about two weeks, with the developer announcing the concluding date several days in advance.
Save files created during any Blind Descent playtest do not carry over to the final release. Because underlying mechanics, world layout, balance numbers, and crafting recipes undergo frequent adjustments between builds, player progress resets when test phases conclude.
Features and Mechanics in the Playtest
Recent test builds incorporate both earlier survival foundations and newly overhauled game systems.
- Map and Navigation: Exploration utilizes a fog-of-war mechanic tracked on your character's in-game Holowatch display.
- Martian Dungeons: Explorers can descend into vast underground spaces, including major locations such as the Amphibious Cave, the Column, and the Silkworm Cave.
- Organic Restoration: Structures built by players trigger reactive infection clusters nearby. If neglected, alien fungi and organisms spread to dismantle bases, while felled flora and dropped items gradually rot and regenerate.
- Dual Progression Paths: Players choose between a technological path that preserves human form through engineered tools and shelter, or a symbiotic path that embraces alien mutations to gain new abilities.
- Scanner System: A handheld scanner analyzes biological specimens and terrain to reveal crafting recipes, environmental hazards, and lore entries.
- Reworked Combat and Movement: Both melee and ranged encounters feature updated animations, accompanied by complete controller support and revised user interfaces.

| Component | Minimum Requirements (Low Preset) | Recommended Requirements (Medium-High Preset) |
|---|---|---|
| Operating System | Windows 10 (latest) or Windows 11 64-bit | Windows 11 64-bit |
| Processor | Intel Core i3-10100 or AMD equivalent | Intel Core i5-12400, AMD Ryzen 5 3600, or higher |

| DirectX | Version 12 | Version 12 |
| Storage Space | 36 GB available space (SSD recommended) | 36 GB available space (SSD required) |
Note that while testing specifications target 36 GB of free SSD storage, the general Steam store page lists a baseline storage requirement of up to 40 GB for the complete project.
How to Report Bugs and Submit Crash Logs
Because test builds represent an active stage of development, players may encounter visual glitches, inventory bugs, or sudden crashes. The development team collects feedback and technical logs through their official Discord server and the Steam Community Hub.
To generate a detailed crash report when encountering stability issues:
- Right-click Blind Descent in your Steam Library and select "Properties."
- Under the "General" tab, locate the "Launch Options" field.
- Enter the command parameter: -gpucrashdebugging
- Launch the game and recreate the issue until the crash occurs.
- Open Windows File Explorer and navigate to your local save directory: %LOCALAPPDATA%\BlindDescent\Saved\
- Archive the entire Saved folder and submit it alongside your system specs, a brief description of the bug, and an optional DXDiag report to the official Discord bug channel or developer contact address.
To generate a DXDiag report on Windows, type "dxdiag" into the Windows Start search, allow the tool to complete its diagnostic scan, click "Save All Information," and attach the resulting text document to your report.
