The Alters Last Variable price on Steam France

The official Steam listing for the add-on shows €14.99 in France. It displays no crossed-out price or discount percentage. This is the regular listed price, not a limited sale.
Last Variable is not a standalone game. The store page says that The Alters is required. Buying the expansion alone will not unlock Jan Scientist’s new story.
11 bit studios estimates around 20 hours of content. That is not a guaranteed completion time. Research, base management, and failed planetary cycles can extend a run.
Which edition includes Last Variable?
Standard Edition owners can buy the expansion separately. Deluxe Edition owners should check their library first, because the add-on is included in that package.
The official PlayStation Store listing names the game, Last Variable, an exclusive outfit, and the soundtrack as Deluxe content. It is a US listing, so do not treat its dollar price as a French store price.
The standalone DLC is the direct choice for players who already own the base game. Deluxe only makes sense for new players who value its extra content.
The Alters Last Variable price and platforms
The €14.99 price is verified on Steam France. The expansion is announced for PC, PlayStation 5, and Xbox Series X|S. Microsoft’s official Xbox page identifies it as add-on content requiring a separately sold game.
Base-game access through a subscription does not automatically include the DLC. Check the offer displayed in your region before paying. PlayStation players should also confirm the edition installed on their account.

What the July 13 expansion adds
Last Variable follows Jan Scientist after he remains on the planet to investigate the Oasis. He works with Geologist, Biologist, Chemist, and Physicist Alters drawn from his own variants.
Terraforming, underground construction, field laboratories, and new resources shape the expansion. Solar cycles still force retreats and cryosleep. This is a story continuation with survival-management systems, not a cosmetic pack.
