The Barrage: The Colorado Connection expansion includes a specific map set on the Colorado area providing a new mechanic: the Bridges.

The Colorado Map includes some new elements: the Construction Sites for Bridges and the Areas for Productive Settlements.

The rivers represented on the Map flow along deep canyons creating clear physical separations between the delimited regions: the presence of bridges built on the crest of the Dams will allow an easier connection between the Productive Settlements of each region; on the other hand, a Dam with a Bridge cannot be further elevated for the rest of the game. Choose carefully when to build them!

The Productive Settlements are new action spaces (4 in the Mountains Area, 3 in the Hills Area, 3 in the Plains Area) that can be activated by placing the required number of Engineers. Activating a Productive Settlement has a cost in Credits that depends on the presence or absence of Bridges along the route from the Construction Site (located on the left edge in the Mountains and Plains Areas and right in the Hills Area) to the Productive Settlement you intend to activate.

You need the base game Barrage to be able to use it. You can also use the Barrage: Leeghwater Project expansion in combination with this expansion.

Dispatch Time

We operate a dynamic stock level system. The items that do not show a stock level are items we can sell as a retailer for those manufacturers. Those items can be back-ordered and we will update you when we have the items in our warehouse ready to ship.

If all your ordered items are in stock we will aim to dispatch your order within 1 working day of receiving your order and will send email confirmation to let you know when it has left us. If any of your ordered items are out of stock we will order them from our supplier at the earliest opportunity, this is usually on a Monday morning. The majority of orders from our suppliers arrive on Thursday or Friday of the same week and we will aim to ship your order out to you within 24 hours of the supplier delivery arriving with us.

If any of your items are on ‘back-order’ then we will attempt to order a resupply. If the items on your order remain out of stock for 2 weeks then we will contact you with some options to refund or wait for a resupply. If you wish alternative arrangements to be made then please contact us at your earliest opportunity after placing your order on our website.
