Abiotic Factor is a survival crafting game set inside a massive underground research facility where a containment breach has released alien creatures. You play as a scientist trapped in the labs, crafting weapons and tools from office supplies and lab equipment to survive. The Half-Life meets Subnautica premise is executed with humor — your first weapons are staplers and fire extinguishers, and your base is built from office furniture barricades. Co-op for up to 6 players adds chaos to the already absurd premise. The game entered Early Access in 2024 and quickly gained popularity for its unique setting and creative crafting system.
This guide covers everything you need: core mechanics, the best builds, equipment worth investing in, location progression, and the tips that actually make a difference.
Core Mechanics
office survival
The facility provides a unique survival context — instead of trees and rocks, you scavenge desks, computers, vending machines, and lab equipment. Hunger is satisfied by vending machine snacks and cafeteria food. Thirst from water coolers. The mundane office setting contrasts hilariously with the alien threat.
science crafting
Crafting uses a research-based system where you study items at science stations to unlock recipes. Combining office supplies creates improvised weapons (staple gun, fire extinguisher launcher). Lab equipment enables more advanced items (tesla coils, chemical sprayers). Each science station type unlocks a different crafting category.
alien encounters
Various alien species escaped from containment, each with unique behaviors. Some are territorial, some hunt actively, some are docile until provoked. Learning each species' behavior and weakness is critical — shotgunning everything wastes ammo on creatures that can be avoided or trapped.
base building
Barricade sections of the facility using office furniture, reinforced doors, and makeshift walls. The existing facility layout (rooms, corridors, elevators) provides natural defensive structure. Securing a section with barricades, lighting, and turrets creates a safe zone for crafting and storage.
co-op research
In multiplayer, research progress is shared but crafting stations can only be used by one player at a time. Coordinating who researches what prevents duplication. More players means faster facility exploration but also more mouths to feed and more noise attracting aliens.
Builds Overview
| Build | Tier | Playstyle | Key Stats |
|---|---|---|---|
| Scientist | S | Stay in the base researching and crafting while others gather materials and fight aliens. | Intelligence, Research Speed, Crafting Efficiency |
| Engineer | A | Fortify the base with turrets and traps, maintain power systems, build infrastructure for the team. | Construction Speed, Electrical Knowledge, Resource Efficiency |
| Security | A | Lead the team into dangerous areas, engage aliens directly, protect Scientist and Engineer players. | Combat Damage, Health, Armor Rating |
| IT Specialist | B | Hack terminals to open locked areas, access security cameras for scouting, reactivate facility systems. | Hacking Skill, Electronics Knowledge, Stealth |
| Custodian | B | Keep the base clean and stocked, cook meals for stat buffs, manage inventory and supplies. | Resource Management, Cooking Skill, Morale Maintenance |
Scientist (S-Tier): Focuses on research and crafting, unlocking the best recipes and equipment for the team. The Scientist prioritizes building and upgrading science stations before combat gear. In co-op, the Scientist is the force multiplier who makes everyone else more effective.
Engineer (A-Tier): Specializes in base construction and turret placement. The Engineer turns facility corridors into kill zones with electric fences, turret emplacements, and automated doors. Their builds passively defend the team while they work.
Security (A-Tier): The combat specialist who takes point during exploration and handles alien encounters. Security builds prioritize weapon damage and durability. The team's vanguard for pushing into new facility sections.
IT Specialist (B-Tier): Focuses on hacking facility systems — unlocking electronic doors, accessing security cameras, and reactivating powered systems. IT Specialists open paths that other builds can't access, including shortcuts and sealed lab sections.
Custodian (B-Tier): The support role maintaining base cleanliness (which affects morale), managing food/water supplies, and handling logistics. Less glamorous but in longer sessions, the Custodian's resource management prevents starvation and morale collapse.

Equipment Guide
| Equipment | Why It Matters | Best For |
|---|---|---|
| Staple Gun | Your first ranged weapon, crafted from an office stapler and rubber bands. | Early game all builds |
| Fire Extinguisher | Repurposed as a short-range spray weapon that slows and damages aliens. | Security (early game) |
| Makeshift Blade | A sharpened piece of lab equipment turned into a melee weapon. | Security, IT Specialist |
| Tesla Coil | An electrical trap placed on the ground that zaps aliens walking over it. | Engineer |
| Chemical Sprayer | Late-game weapon spraying corrosive chemicals that dissolve alien armor. | Security (late game) |
Staple Gun: Your first ranged weapon, crafted from an office stapler and rubber bands. Low damage but infinite craftable ammo from staple boxes found in every office. Effective against small aliens and as a distraction tool.
Fire Extinguisher: Repurposed as a short-range spray weapon that slows and damages aliens. The CO2 cloud obscures vision, useful for retreating from tough encounters. Found in hallway emergency stations throughout the facility.
Makeshift Blade: A sharpened piece of lab equipment turned into a melee weapon. Higher damage than the staple gun but requires close range. Stealth attacks from behind deal 3x damage, rewarding careful approach.
Tesla Coil: An electrical trap placed on the ground that zaps aliens walking over it. Crafted from lab electrical components. Multiple coils create kill corridors that clear aliens without ammo expenditure. The Engineer's signature weapon.
Chemical Sprayer: Late-game weapon spraying corrosive chemicals that dissolve alien armor. Requires rare chemistry lab components to craft and refill. The highest DPS weapon in the game but ammo is expensive and limited.
Location Progression
| Location | Level Range | Key Rewards |
|---|---|---|
| Office Floor | Starting zone | Basic supplies, starting crafting materials, safe base location |
| Labs | Early-mid game | Science stations, lab materials, advanced crafting recipes |
| Parking Garage | Mid game | Metal materials, vehicle parts, large-scale building components |
| Server Room | Mid-late game | Computer access, security camera network, automated defenses, electronic components |
| Deep Labs | Late game | Endgame blueprints, rare materials, story completion, best weapons/armor |
Office Floor: The starting area with cubicles, break rooms, and supply closets. Abundant basic resources (food, water, office supplies) but weak alien threats. This is where you establish your first base and learn mechanics.
Labs: The research wing containing science stations and specialized crafting components. More dangerous with escaped lab specimens. The chemistry lab, biology lab, and physics lab each contain unique crafting materials.
Parking Garage: A large open area with vehicles that can be scavenged for metal and mechanical parts. The garage connects to the surface exit (blocked by heavy debris). Alien nests form here due to the open space.
Server Room: A high-security area requiring IT specialist skills to access. Contains the facility's computer network which, when restored, provides camera access and automated defense controls. Cold environment due to server cooling.
Deep Labs: The lowest facility levels where the containment breach originated. The most dangerous area with the strongest alien types and environmental hazards (radiation, toxic spills). Contains the best equipment and crafting blueprints.
Tips That Actually Matter
- Build a science station before anything else. Research unlocks exponentially better equipment — 30 minutes of research is worth more than an hour of scavenging.
- Vending machines are your best early food source. They respawn on a timer. Mark vending machine locations on your map and create a collection route.
- Tesla coils placed in corridors create automatic kill zones. Set up 3-4 in a row leading to your base entrance and aliens die before reaching you.
- Noise attracts aliens. Crafting, building, and fighting all generate noise. Do noisy work in batches, then go quiet to let the area cool down.
- The fire extinguisher isn't just a weapon — the fog cloud blocks alien line of sight, letting you retreat through a smokescreen.
- In co-op, specialize roles. One player researching while another gathers materials is twice as fast as everyone doing both.
- Barricade with office desks first — they're everywhere and provide decent protection. Upgrade to reinforced walls once you research them.
- Light keeps some alien types away. Well-lit areas have fewer spawns. Prioritize restoring power to lighting systems in your base section.
- Food spoils. Build a refrigerator from the kitchen components early. Spoiled food gives food poisoning, which drains health and stamina for hours.
- The Deep Labs require radiation protection gear. Don't go down there without it — radiation damage is constant and lethal within minutes unprotected.
Common Mistakes to Avoid
- Exploring too far from your base without establishing a safe return route. Getting lost in the facility with low health and no supplies means death.
- Ignoring science stations to focus on combat. Better weapons come from research, not from scavenging. A researched chemical sprayer outperforms any found weapon.
- Fighting every alien instead of learning which ones can be avoided. Some aliens are territorial — walking around their area costs nothing. Walking through it costs ammo and health.
- Building your base in an indefensible location like an open lobby. Corridors with single entry points are the best base locations — only one direction to defend.
- In co-op, everyone exploring in different directions. The facility is dangerous and getting separated means no one can help when aliens attack.
Frequently Asked Questions
