Stellaris Patch 3.12.3 Andromeda Out Now with Teasers for Cosmic Storms
Stellaris patch 3.12.3 brings tradition agendas, megastructure dismantling, and sweeping balance updates for synthetic ascensions and civics. Meanwhile, Paradox outlines plans for the 3.13 Vela update, introducing galactic weather systems later this year.
Stellaris update 3.12.3 is rolling out this week, packed with quality-of-life adjustments, new tradition agendas, and balance adjustments for synthetic ascension paths. Alongside the patch notes, Paradox offered a small preview of the upcoming 3.13 Vela expansion.
New Features and Quality of Life
Patch 3.12.3 adds tradition agendas for Modularity, Nanotech, and Virtuality paths. Players who possess the required technology and are not at war can now dismantle select megastructures, such as kilostructures, with Scavenger civics refunding 10% of base costs for buildings, districts, and megastructures. Solar system tooltips now display arc furnace and habitat potential, and top-menu resource tooltips have been redesigned for clarity.
Synthetic and Empire Balance
Virtual empires now access a dedicated Virtual Economic Policy, while Machine World designations increase job output by 5% and resource district build speeds by 25%. Cybernetic Creed civics receive adjustments to pop modification rules, faction approvals, and specialized modifiers depending on chosen spiritualist factions. Synthetic authorities and corporate governments receive targeted buffs to leader bonuses, trade values, and researcher outputs, alongside reductions to Dark Matter Engine effects from 60% down to 40%.
Bug Fixes and Modding Changes
The patch addresses stability issues and bugs, including fixes for out-of-sync errors during hotjoins, crashes when switching countries in observer mode, and incorrect exploration failure probabilities for archaeology and astral rifts. Modders gain new election term variance modifiers, and several existing triggers and console commands have been renamed or refactored.
Looking Ahead to 3.12.4 and 3.13 Vela
Patch 3.12.4 is currently targeted for a June 13 release and will likely close out the 3.12 Andromeda cycle ahead of summer vacations. Following that, the autumn 3.13 Vela update will introduce Cosmic Storms, bringing dynamic galactic weather and prediction technologies to the game.
Why this patch matters
Patch 3.12.3 delivers vital tuning for synthetic ascensions and long-requested quality-of-life features, setting a stable foundation before the 3.13 expansion introduces weather systems.
