Reservoir and base economy

Tiles Survive reservoir should be treated as part of the base economy. Without verified data, it would be wrong to list exact production, speedups, costs, or upgrade values.

Before upgrading, open the current game screen and check the shown requirements, resources, and queues.

Resource planning

Do not spend food, wood, metal, or fuel without a near-term goal. If the reservoir competes with heroes, squads, power plant, or events, decide the priority first.

Compare available upgrades and choose the one that best supports the current plan.

Routine checks

Keep the reservoir in a base checklist with resources, squads, gold mine, rewards, and events. This is simple but prevents missed details.

Tiles Survive Helper may help with repeated checks and resource routine for supported features, but it does not promise specific reservoir output.
