Endlessly roaming through the Space, an alien fleet is closing to a blue planet. Its inhabitants, blissfully unaware of the upcoming threat, are struggling with the chaos they have to face everyday. And yet, it will all soon change. The world will finally become united against a common enemy. The Earth will never be the same anymore. But what will this war bring? Do the humans stand any chance against such a foe? Will everyone willingly join to fight the alien thread? And why, do the aliens seem to look so human-like?...
First officially identified in the city of Wanamingo, Stalkers are confirmed to be fully mechanical and autonomous. They seem to possess an ability to disappear in plain sight, making them impossible to spot with any optical device, and perfect for ambushes.
Because of this, Essence is forced to use Artemis Walkers to detect electromagnetic anomalies whenever a Stalker presence is a possibility.
Unfortunately, they are difficult to kill even if visible, as, like all Vintarid machines, machinegun fire seems to pass through them doing little damage. As if that wasn't enough, their tentacles seem to cut through metal like through butter.
