Steamwatchers: Spark of Hope

With Spark of Hope, you'll be able to use mobile structures, the Caravans, to make your Clan stronger and more influential. Have your Caravans evolve each turn to gain even more adaptability. But beware, only Careeners can build them, and they will certainly remind you of what you owe them.

—description from the publisher

Spark of Hope is all about a new type of miniature: Caravans.

These vehicles are like mobile structures, but they come with a cost: you need to provide upkeep to benefit from their powerful abilities.

The three vehicles will allow you to specialize your caravan to better your production, your military prowess, or your logistic ability. First and foremost, the caravan is a mobile algofuel production unit. When on a steam column during Thaw, it may produce algofuel barrels with which you can further develop your vehicles by installing Kits on them, or by improving existing Kits.

This expansion also includes new Scenario and Archon cards for the main game.
