How the 100-player limit works
Up to 100 players online at once. This limit includes all players in private Homes and active Raids. You keep your place when moving between them. Each player counts only once.
Keep your progress. Risk your equipment. A Raid fits into an evening. If you die, other players can take your equipment and sell it on the player Market.

More about buying and selling
BUY // Available supplies Buy food, water, medicine, tools, and equipment for immediate use. Each item shows how many you can still buy, when your stock limit resets, and the full price.
SELL // Items you can sell The trader checks your carried items and all ten Home crates. Choose an item and quantity. The payment goes straight into your Humidor. Higher trader trust gives you better prices.

The player Market
Cigarettes are the in-game currency.
How item values work
Each item has a base value in cigarettes. This depends on how rare it is and how much it costs to craft. Crafting costs include materials, required skills, and tool wear, with a limit on wear costs. Traders, stored items, and the Market use this same base value.
Trade with the four traders for immediate purchases and payments. Or offer an item on the player Market at your own price. Pay the displayed 5% listing fee, then wait for another player to buy it. Each offer shows the exact item, its condition, and its price in single cigarettes. Change and seller payments are automatic.
Traders, Market, and your Humidor
- Traders Buy and sell immediately. Higher trust gives you better prices.
- Market Trade with players. Check the item, its condition, and the seller's price.
- Humidor Your money balance, shown as cartons, packs, and single cigarettes.
