Fields

Fields are your home base in PetroNad. They house your Rigs and produce the Energy needed to keep them running. Upgrade your Field to expand your empire's capacity.

Fields house Rigs. Field tiers can be upgraded (level-by-level) using $PETRO. Every Field has three parameters:

1. Max Items: The maximum number of Rig the Fields can hold.

2. Energy Capacity: The total power limit of the Field. This is a static capacity, not a production rate. Each Rig requires and occupies a specific portion of this capacity to operate. You can only place Rigs as long as the Field has enough available energy capacity.

3. Upgrade Cost: The $PETRO (or initial $MON) cost to acquire or upgrade a Field.

Rules:

• There is a 24-hour cooldown before the next upgrade (except from Tier 1 to Tier 2).

• There is a maximum of 1 Field per wallet.

• Fields must be upgraded sequentially (Tier 1 -> Tier 2 -> Tier 3...).

• Fields also have a "Decommission Rig" option, allowing you to remove old Rigs to make space for new ones.

• To place a Rig, the Field must have both an available slot (Max Items) and sufficient Energy Capacity.

For fairness, everyone starts the game on the same foot by acquiring the Tier 1 Field with $MON. All subsequent upgrades are paid for in $PETRO.
