In Blind Descent—the sci-fi underground survival game developed by Pokuch and published by META Publishing—the objective to "explore the column" marks the primary story dungeon in the demo and playtest builds. This massive alien structure lies deep beneath the Martian surface and tests your gear, puzzle-solving, and combat preparation before unlocking game-changing mutations.
How to Unlock the Explore the Column Objective
Before the Column becomes your active destination, you must progress through the opening survival storyline:
- Craft basic tools and survive the surface area: Establish a small base camp by harvesting wood, stones, and vines. Build a fire pit, boil water, and craft a workbench using split logs.
- Handle the comms sequence: Depending on your playtest path, you either repair the radio tower using an antenna plant gathered at the waterfall overlook (requiring a sour lung bulb for the purifier system) or unlock the distress call sequence through your AI assistant, Hollow Watch.
- Locate Hakan: Follow the distress signal marker roughly 500 meters toward the central sector. You will find Hakan mortally wounded and leaning against alien remains.
- Acquire his gear: Speak with Hakan until his dialogue concludes. After he passes away, download his encrypted logs and pick up his dropped gear (the grappling hook gun / multi-tool). Hollow Watch then identifies the massive pillar in the distance and designates it as your next primary objective: Explore the column.
Gear Check: Preparing for the Column Descent
As you approach the mouth of the Column cave, Hollow Watch initiates a Preparedness Scan. Entering underprepared makes navigating the dark interior and surviving enemy ambushes significantly harder.
Before stepping inside, ensure you have gathered the following equipment:
- Melee Weapon: A Stone Sword or crafted Spear. The Spear provides better reach against low-crawling bugs, while the Sword delivers swift horizontal and vertical strikes. Note that weapon durability drops rapidly against armored bugs; carry a backup tool such as a Stone Axe or Pickaxe.
- Shield: A Wooden Shield is essential. It completely negates projectile attacks from ranged enemies and absorbs heavy hits from chargers.
- Ranged Weapon: A Makeshift Bow crafted with long branches, vines, and utility spools/silk. For ammunition, harvest reeds or shoot the straight spines produced by exploding flora (which function directly as arrows). Stock roughly 40 to 60 arrows.
- Light Source: Craft a lantern (such as a Firefly lantern or waist-mounted plant light) or gather Lunar Light nodes. Attaching a light to your waist keeps your hands free to hold both a weapon and a shield.
- Medical Supplies: Carry at least 5 to 10 healing bandages or pigment/mender gels, alongside an infection suppressor if your environmental resistance drops.
- Sustenance: Consume high-tier cooked meat to boost your maximum HP pool before entering, and top off your hydration with a canteen or water cone.
Step-by-Step Walkthrough: Inside the Alien Facility
The Column transitions from natural caverns into a manufactured alien research complex. Follow these steps to navigate through the interior sectors:
1. Powering the Entryway
Enter the cave descent and drop into the lower chamber. You will locate an initial alien room equipped with sleeping beds.
- Pick up the loose alien battery found near the central console area.
- Insert the battery into the glowing green Energy Socket / Battery Socket on the central cylinder.
- This restores lighting to the surrounding sector and unlocks the initial security blast doors. Use the beds to set your respawn point before moving deeper.
2. Clearing the First Corridors and Acid Spitters
Proceed through the opened blast door into the metal corridors:
- Silkworms: Small, low-profile worms will crawl along the floors. Aim downward or use vertical weapon swings to connect hits.
- Spitting Bombardier Beetles: These enemies fire explosive acid projectiles. Raise your Wooden Shield to block the glob; if you charge directly at them with your shield raised, the projectile will detonate at point-blank range, damaging or killing the beetle itself.
- Alternatively, use explosive barrels scattered throughout the halls to eliminate clustered enemies from a safe distance.
3. Overriding the Security Console and Bypassing Steam Vents
Follow the lit cables running along the ceiling and walls to find the first alien computer terminal:
- Interact with the alien console to allow Hollow Watch to upload the decryption key.
- Select Initiate Unlock Sequence to clear the biohazard containment lockdown on the interior blast doors.
- In the adjoining corridor, timed steam vents will block your path. Wait for the steam cycle to pause, move across, and interact with the wall switch to shut down the venting hazard permanently.
4. Opening the Central Containment Chamber
Proceed past the classrooms and egg-filled side chambers until you reach a large circular arena sealed by heavy revolving bulkheads.
- The door mechanism requires batteries placed into both left and right feeder sockets.
- Search the flanking side corridors. Fight through the silkworm clusters, avoid flammable egg clusters, and retrieve the required batteries.
- Slot the batteries into the corresponding colored sockets. Once all indicator conduits glow green, the central containment unit will unlock.
Boss Fight: Silkworm Queen / Corrupted Entity
Once inside the arena, the lockdown releases a massive boss encounter (the Queen Silkworm / Corrupted Queen).
| Combat Phase | Boss Mechanics | Recommended Strategy |
|---|---|---|
| Ranged Assault | The Queen spits toxic gases and acid clouds that blur vision and inflict damage over time. | Keep moving backward along the outer edge of the arena. Keep your shield raised during spit windups or take cover behind structural pillars. |
| Add Spawns | Minor silkworms and flying mosquito pests disrupt your positioning. | Let the Queen's sweeping attacks and projectiles cleave through the smaller mobs, or clear them quickly using your Spear's long thrusts. |
| Vulnerable Windows | Pauses briefly after lunging or discharging heavy gas bursts. | Fire arrows into the weak points of the head, or move in with a Spear/Sword for quick strike cycles before raising your shield again. |
Stay mindful of your weapon durability. If your primary blade breaks mid-fight, swap immediately to your backup tool or throw rocks and explosive pods to finish off the remaining health bar.
Unlocking Symbiosis and Overriding the Facility Lockdown
Defeating the boss unlocks the final narrative and gameplay progression available in the playtest:
- Interact with the Plant: Approach the pulsing organic flower inside the opened containment unit. Interacting with it grants your character a permanent mutation (such as adapted lungs or symbiotic resonance).
- Clear the Blocked Path: Walk up to the dense infection tendrils blocking the exit corridor. With your new mutation, raise your hand—the bio-matter recognizes your DNA and retracts to clear the path.
- Deactivate the Facility Lockdown: Head to the master computer terminal. Review the expedition data logs regarding the bipedal experiments, then initiate the command to deactivate the layer-wide lockdown.
- Take the Elevator to the Surface: Step into the extraction elevator. Once you return to the upper caverns, you will discover that disabling the facility lockdown has drained the central lake, revealing an open descent hatch and massive underground complex leading to the deeper Martian layers.
