Blind Descent playtest coop lets up to four players explore the subterranean Martian jungle together in an early development build created by Pokuch and published by META Publishing. While earlier testing phases were limited strictly to single-player exploration, the dedicated co-op playtest opened multiplayer functionality so teams can build shelters, harvest Martian flora, and fight native wildlife side by side.
How Multiplayer Co-op Works in the Blind Descent Playtest
The co-op playtest is built specifically for groups of up to four pioneers, though you can still choose to venture into the Martian depths solo. The development team runs playtests through Steam, allowing participants to sign up directly via the store page or accept friend invite passes distributed through Steam gated access.
- Register for testing access directly through the Blind Descent Steam store page during an open playtest phase.
- If selected, install the playtest client from your Steam library.
- Invite up to three Steam friends directly into your lobby, or coordinate with other players in Discord to form a squad.
- Launch the session together, taking care not to join midway through the opening elevator crash sequence so player menus and inventories initialize properly.
Multiplayer sessions do not feature friendly fire, meaning teammates cannot injure each other with melee swings, arrows, or thrown items. However, cooperative management is vital for survival. The squad must coordinate sleeping schedules, share base generator fuel, and communicate during resource runs to avoid squad wipes.
Playtest Content, Length, and Available Dungeons
The cooperative playtest offers approximately four hours of gameplay, depending on exploration pace and how your team approaches base building and combat. Rather than providing the complete open world planned for the full Early Access release on December 2, 2026, the playtest focuses on a curated slice of the Martian underground.
| Feature / Location | Playtest Availability & Details |
|---|---|
| Max Team Size | 1 to 4 players online |
| Estimated Session Length | Approximately 4 hours (2 to 5 hours depending on playstyle) |
| Major Dungeons | Amphibious Cave, Column, and Silkworm Cave |
| Progression Paths | Technological path (science/tools) and Symbiotic path (alien mutations) |
| Fast Travel System | Pink tendril fast travel points unlocked across caverns |
| Platforms Supported | PC via Steam (DirectX 12 required; console cross-play planned for full release) |
Exploration in this build utilizes a fog-of-war map displayed through your wrist-mounted Holowatch interface. Progression is driven by the Adaptation system rather than traditional static quest logs, pushing your squad to react dynamically to hazards like acidic rain and invasive pathogens.
Squad Survival and Resource Management
Surviving as a team requires balancing personal maintenance with base development. After crashing down the elevator shaft, your squad must clear an abandoned research outpost and bring its primary systems back online.
Generators require energy sources, such as electric plant bulbs, to provide power to critical utility stations. Once the base is powered, teams can hook up a water purifier using punctured watermelons and hollow plant stalks to produce clean water. Cooking ingredients like seed pods and Faux-mato inside the nutrient processor grants maximum health buffs that last for several minutes.
Sleeping is synchronized across all players. Beds—such as repaired leaf mattresses—require teammates to interact and confirm they are ready before advancing the clock.
Combat involves crafted weapons like stone axes, wooden clubs, bows, and makeshift weapons combining handles with materials like slime or electric sacs. Players can also throw loose rocks, watermelons, and explosive pods at range.
If a player dies, they drop their backpack containing their inventory. While squad members can help defend the area, aggressive alien creatures often linger near player corpses, making recovery difficult. Dying a second time before retrieving your belongings results in your dropped loot despawning.
Known Bugs and Playtest Fixes
Because Blind Descent is actively in development, playtesters frequently encounter technical issues, balance quirks, and performance drops. The developers have released patches during testing to address critical bugs reported by the community.
- Opening Cutscene Sync: Early playtest builds allowed players to join during the intro sequence, causing broken Tab menus and locked inventories. A patch updated the lobby flow so new players wait until the initial infection cutscene finishes.
- Bed Interface Cancelation: An issue where one player exiting the bed interface canceled sleep readiness for everyone in the session was resolved in a playtest patch.
- Audio Levels and Settings: Players noted that respawn noises, falling acid rain, and ambient storms were excessively loud. Additionally, testing showed voice chat volume and dialogue sliders were accidentally swapped in the audio settings menu.
- Creature Desync: Testers observed occasional entity glitches where creatures, such as tortoises, lizards, and mites, vanished when looking away or phased below terrain geometry during combat.
- Item Inputs: The developer clarified that applying infection suppressants requires using the left mouse button after selecting the item, rather than pressing the outdated E prompt displayed in older tutorials.
Frequently Asked Questions
Does my progress from the co-op playtest carry over to Early Access?
No. Playtest saves will not carry over to the final release or Early Access. Systems, crafting balance, and map structures are continually evolving across testing phases.
Can I play the Blind Descent playtest on PlayStation with PC friends?
Not during the current playtest. While Pokuch confirmed cross-platform multiplayer between PC and consoles for the future, current testing builds are hosted exclusively on PC via Steam.
What are the PC system requirements for the Blind Descent playtest?
The playtest runs on Unreal Engine 5 and strictly requires DirectX 12. Minimum specs demand Windows 10/11, an Intel Core i3-10100 (or AMD equivalent), 16 GB of RAM, a GTX 1080 Ti (or equivalent), and 36 GB of storage space. Recommended specs include an Intel Core i5-12400 (or Ryzen 5 3600), 32 GB of RAM, and an RTX 3060 12 GB.
How do you report bugs encountered during a multiplayer session?
Bug reports can be submitted through Discord in the bug-report channel or on the Steam Community Hub. The team requests a description of the issue, system specs, reproduction steps, screenshots or video, and an exported DXDIAG file.
