Holospark's Earthfall is a co-op survival shooter where up to four players take on the aliens that have invaded Earth. The title is currently in Early Access on Steam, and the development team has detailed a new map, Revelation, that has arrived on that platform.The new map looks serene on the surface. The small northwestern town is covered in snow, but the calm hides a dangerous secret. Players must search for a tracking device and retrieve the data from it, but the aliens won't be terribly pleased about it. Take a look at the screens below to see the map in action.Earthfall and its Revelation map is available now.
