About Lab 47
Lab47 is a cooperative exploration adventure game centered around interdimensional portals.
As a member of an experimental exploration team, you will activate a laboratory portal that leads to entirely different worlds—each one shaped by unknown forces, failed experiments, or realities beyond human understanding.
From endless backroom-like spaces to deep pool-like structures, twisted magical realms, and surreal dimensions, every portal opens the door to a new adventure.
🚪 Interdimensional Portal Exploration
Use the laboratory’s portal to travel to a variety of themed worlds. Each world features its own atmosphere, rules, events, and points of interest, ensuring that no two expeditions feel the same.
👥 Cooperative Multiplayer
Explore alongside friends in online co-op. Coordinate movement, share discoveries, and work together to face unfamiliar environments and unexpected events.
🌌 Diverse Worlds and Themes
Encounter worlds inspired by horror, dark fantasy, magic, and mysterious realities. These dimensions range from unsettling and surreal to visually striking and otherworldly.
📦 Discovery and Item Collection
Search each world for valuable artifacts, materials, and special items. Everything you find can be brought back to the laboratory after the expedition.
🔧 Trading and Equipment Progression
Sell or exchange collected items to obtain new equipment, tools, and upgrades, unlocking access to more dangerous or unusual worlds.
🧩 Event-Driven Adventures
Lab47 is not a survival game. The focus is on exploration, atmosphere, and events. Each portal jump may trigger unique encounters that shape the course of the expedition.
Your Mission
Enter the portal
Explore the unknown
Bring discoveries back to the lab
Prepare for the next expedition
In Lab47, there is no single path—only worlds waiting to be opened.
