Overview
Coal Output increases Coal Output. It is available in 5 tiers (Coal Output I, Coal Output II, Coal Output III, Coal Output IV, Coal Output V), each with multiple upgrade levels.
Research costs include 5 resources: Resource, Meat, Wood, Coal, and Iron. Prerequisites require a specific Research Center level and, for higher tiers, completion of previous tiers. Construction times are base times and do not account for Research Speed bonuses.
