Stellaris celebrates 10 years with free weekend and Season 10 roadmap

Stellaris is using its 10th anniversary to do something rare for a decade-old grand strategy giant: make itself feel newly approachable. The base game is free to play for the weekend, the Anniversary Edition is 70% off at $17.99, and Season 10 gives both newcomers and long-time commanders a clear look at where Paradox wants the galaxy to go next.

The timing is the point. Paradox ties the celebration to May 9, the game’s launch date, and says it has spent 10 years “exploring this vast galaxy full of wonders” with the community. That anniversary push now overlaps with a free weekend that runs through Monday, June 22 at 10 a.m. PT, 1 p.m. ET, 6 p.m. BST and 7 p.m. CEST, while the 70% discount on the Anniversary Edition lasts through Thursday, June 25. For anyone who has looked at Stellaris’ reputation for sprawling systems and endless DLC and bounced off, this is the cleanest test run the game has had in years.

Paradox is also cutting down some of the intimidation factor at the base-game level. On March 19, the company said Utopia, Synthetic Dawn and the Humanoids Species Pack would be added to the base game on May 11, while the price of the base game would rise by $10. That bundle gives every player access to Hive Mind empires, Gestalt Machine Intelligences, humanoid portraits, civics and shipsets, which is a meaningful widening of the vanilla experience before anyone even buys an expansion.

Season 10 is the other half of the pitch. Paradox frames it as the 2026 roadmap and describes it around “resilience and movement,” with Nomads available now, Willpower due in Q4 2026, and two Season 10 scenario packs also set for Q4 2026. The pass includes an instant-unlock Vipra the Vapor portrait with five phenotypes and custom animations, a small but unmistakable signal that this is not a wind-down cycle.

Nomads itself leans into the kind of left-field design that keeps Stellaris alive. It lets players build nomadic empires around Arkships instead of ordinary territorial sprawl, then adds Waystations, Waylines and a Contract system for structured interactions with other empires. Paradox has also opened an official 10th anniversary merchandise store, and on the console side, Cosmic Storms and Grand Archive are lined up for May 25, 2026.

For first-time players, the advice is simple enough: start with the United Nations of Earth and use the free weekend to see whether Stellaris’ famous depth clicks. For veterans, the answer is more pointed. Ten years in, Paradox is not treating Stellaris like a museum piece. It is treating it like a game with more map left to explore.
