Corps of Discovery: Expansion 2 – Vameter

From BoardGameGeek:

As they explore deeper into the heart of the continent, the Corps of Discovery encounter the Fezron, a species of small, sentient, blue-feathered beings. You share a mutual enemy with the Fezron in the form of the Vameter, a vicious, winged predator that claims the heads of its victims as its own. The Fezron and the crew of the Corps must work together in order to weaken the Vameter and then trap it. You'll need to plan carefully and be willing to make sacrifices to give your sharpshooters the best chances of putting a bullet into the beast before it takes to the air to elude capture. -description from the publisher
