Zombicide - Invader: Dark Side (EN)

From the publisher:

On the planet PK-L7, humanity thought it had found the answer to its prayers when Xenium was discovered there. This substance could be used to make a powerful fuel that would send civilization across the stars. But, as mining operations got underway, the seemingly peaceful aliens changed, becoming murderous.

Now, few Survivors are left, including Green Squad, a group of operatives that had been deep below the surface when the attacks started. Who will make it out of the tunnels alive? Dark Side is a standalone expansion for Zombicide: Invader. Players take on the role of members of Green Squad and must fight their way through a 10-mission campaign, battling the dangerous and deadly Driller Xenos along the way. Will it be humanity or the aliens that make it to the surface first?
