🧪 Green Gas

Not everyone is your friend.

Green Gas is a multiplayer social–strategy game where trust is the most fragile and dangerous resource.

In each match, players take on the role of Cells, working together to repair the main generator —

but hidden among them is a Cancer, whose goal is the exact opposite…

Roles

Cells

Collect money and resources

Identify and eliminate the Cancer before it’s too late

Cancer

Sabotage and create chaos

Steal money

Use toxic gas, traps, and deception

Prevent the generator from being fully repaired or eliminate the Cells

Win Conditions

✅ Cells Win By :

Repairing the generator to 100%

Or successfully eliminating the Cancer

❌ Cancer Wins By:

Preventing the generator from being completed

Or eliminating the Cells before repairs are finished

Money, Tools, and Sabotage

How does the Cancer grow stronger?

Stealing money from rooms

Transporting money through underground tunnels to their personal account

Spending money on:

- Green toxic gas or toxic water

- Traps to hunt or slow down Cells

- Deception, lies, and misinformation

If the Cells remain confused and waste time → the Cancer wins.

- Cell Objectives

Collect money and deliver it to the main room

Gather metals and convert them into money

Buy keys to unlock sealed rooms for more resources

Purchase tools to repair the generator faster

Coordination, healthy suspicion, and timely decisions are vital

- Toxic Gas – Will You Survive?

Being exposed to green toxic gas doesn’t always mean instant death.

Each time you enter toxic gas:

A mini-game is triggered

Win it → you survive

Lose it → you are eliminated

- Generator Progress Stages
