Nemesis, as its name suggests, finally lets Stellaris players properly embrace their dark side by giving them the opportunity to initiate a crisis. Usually these are late-stage events that mark the arrival of powerful AI forces who’ll either perish in bloody battle or eradicate all known life, but Nemesis will let human players mastermind the galaxy’s devastating denouement themselves. First, however, they’ll need to perform nefarious deeds and accrue Menace, which is used to ascend through the ranks of evil, eventually unlocking the Aetherophasic Engine - a doomsday device powered with the dark energy created by consuming the stars. Players who’d prefer to cast themselves as heroes can adopt the mantle of Galactic Custodians, using Nemesis’s new tools - including espionage and covert operations - to thwart the forces to evil. Both sides will be establish spy networks, gather valuable intel, acquire assets, steal research, and manipulate the truth in their quest for domination. All that comes to Steam, GOG, and the Microsoft Store on 15th April with the launch of Stellaris’ Nemesis expansion. Consoles players will be able to enhance their space-faring adventures, this time courtesy of the Lithoids Species Pack, on 25th march. This smaller-scale expansion introduces a new rock-based species to the galaxy by way of new portraits, a new voice pack, ship models, and unique mechanics for Lithoid Empires. You can get a glimpse of that in the trailer above.
