Large Lem update (v3.1) released for the PC version

Paradox Interactive today released the big Lem update for the PC version of Stellaris (from 35,99€ at to buy) . This free expansion adds new content to both the original game and several of its expansions. The base game Stellaris will also be free to play throughout the weekend.

“Our inspiration comes from many different sources, be it the works of science fiction authors around the world or our own ideas from the past. We keep finding new stories that we want to tell with Stellaris,” says Daniel Moregard, Stellaris game director. “This patch gave us a unique opportunity: This year marks the 100th birthday of Stanislaw Lem, a Polish science fiction writer whose stories have been a fantastic inspiration for the Stellaris team. In addition to some direct references to Lem’s work within the Game for observant fans, the Lem update refreshes the content our fans have enjoyed throughout the history of Stellaris. “

Paradox Interactive: “The Lem-Update, named after the well-known Polish sci-fi author Stanislaw Lem, is the first release by the newly formed Custodians team within the Paradox Development Studio. The Custodians team focuses on the development of free content, balance and updates for Stellaris and improves both the base game and previously released downloadable content. The Lem update adds new content and gameplay features to Stellaris, including:

  • Custom tradition trees where players can choose which trees to chase.
    • For the Plantoids Species Pack, there are two new state elements and three new species properties:
    • The state element ‘Idyllic Blossom’ (restricted to plantoid or fungoid species) enables the construction of Gaia Seeder buildings.
  • The state element ‘Catalytic Process’, which is available to species with and without swarm consciousness, exchanges metallurgists for catalyst technicians. These technicians turn energy credits into alloys. Also works with machines and lithoids.
  • Players who own the Humanoids Species Pack will have the option to raise a powerful clone army, create an empire of master craftsmen, or lead an empire fueled by the sheer decadence of pleasure addicts.
  • The state element ‘Revived Armies’ has been renamed to ‘Reanimators’. Exclusive to Necroid players, the afterlife is now available with more dynamic options for reviving targets, including the ability to revive Leviathans and enemy troops during battle.
  • New tradition trees have been added to both the Nemesis and Apocalypse DLCs, as has a new trading tradition in the base game. In addition, players can now choose seven out of up to eleven tradition trees (with all DLCs).
    • Nemesis owners get access to the traditional Subterfuge tree, which grants bonuses if they succeed in spying or if their enemies fail.
    • Apocalypse owners gain access to the Tree of Relentless Tradition, which greatly enhances the capabilities of their defensive starbases.
  • Major updates to game balance, including reorganizations of Ascension Perks, Civilizations, Ethics, and Lineage.
  • Numerous bug fixes and various AI improvements to improve the overall quality of Stellaris. “
