Amplitude Studios now offers Shadows, a new DLC pack for Endless Legend on Steam, adding new espionage gameplay to the 4X strategy game. A new Shadows of Auriga trailer accompanies the release, and here's an outline of what it involves:

The Forgotten are the latest major faction to be introduced in Endless Legend Shadows. Masters of deception and subterfuge, they were assumed lost or dead by all. Against their will, the faction were forged into a tight society of violent and distrustful survivors, having spent the final years of the cataclysm alone on the surface of Auriga. A violent and distrustful society, who after many years have emerged from the shadows once more in the hopes that the other factions will accept them - or kneel before them.
