Barrage

Play five rounds: Income and Headstreams, Actions, Water Flow, Scoring, then End of Round. Take turns placing the required Engineers on one available action space and resolving it until everyone has used their Engineers. Most shared spaces remain occupied for the round; the Bank is an exception.

For construction, use your Company board’s spaces from left to right, insert an appropriate or wild Technology tile and all required machinery, then immediately rotate the wheel one segment clockwise and place the structure. Reclaim machinery and tiles when they return to the open segment. Round end does not empty the wheel; Workshop and other effects can accelerate it. Spent Credits return to the supply, never to the wheel.

Bases cost five, four or three Excavators in Mountains, Hills or Plains; Elevations cost four, three or two Concrete Mixers respectively. Raise only your own dams, to level three at most. Conduits cost twice their production value in Excavators; powerhouses cost two Concrete Mixers plus one per existing powerhouse. Red-bordered building spaces add a fee. Neutral dams cannot be modified.

Production requires water in your own or a neutral dam, a legal conduit of any player’s color, and your own powerhouse. Multiply water drops by conduit value, then apply action and Company modifiers. For an opponent’s conduit, pay its owner one Credit per drop; that owner also scores one VP per drop. The production must yield at least one Energy Unit.

Contracts use a single production, never the sum of several productions, with at most one private or National Contract fulfilled per production. Record the energy on the round track as well; fulfilling a contract does not spend it. Hold at most three unfulfilled contracts; completed contracts do not count toward that limit.

After production, water leaves the powerhouse along natural rivers, one drop at a time. It stops at dams with remaining capacity, overflows full dams and is removed only on leaving the map. A normal dam holds one drop per level. New headstream water normally waits until Water Flow; actions explicitly showing immediate flow are exceptions.

The first and second energy producers normally score six and two VP, provided they produced at least one Energy Unit; ties use the printed split rules. At least six energy is required for the current Bonus tile; subtract four VP for each energy section behind the current round, to a minimum of zero. Zero energy also loses three VP. Construction unlocks income immediately and again in later Income phases.

After round five scoring, award the final Objective’s first three places 15, 10 and five VP, sharing tied tiers and rounding up. Score one VP per combined five Credits and machinery in your personal supply, plus one per water drop in your dams. Machinery still on the wheel does not count. Most VP wins; break ties by energy produced in the final round.
