In Barrage, you have 12 engineers to use in each of the 5 rounds. So your maximum number of available engineers for the game is 60. And, because it is a workplacement game, the action spaces have different cost in resources or number of engineers. Because of that, one of your best strategies to get more value in the game is liberating income as soon as possible. To do that, you need to build and manage your machinery plus your constructing wheel.
