The Alters gets a massive DLC — Last Variable is out now
Polish studio 11 bit studios — the team behind This War of Mine and Frostpunk — has released Last Variable, a major expansion for The Alters. It's out now on PC (Steam, Epic, GOG), PS5, and Xbox Series X|S at $19.99, and included free in the Deluxe Edition. Early Steam reviews sit at 94% positive, with critics scoring it 81 on OpenCritic.
The new content
Last Variable picks up from the Jan Scientist ending of the base game. Jan stays behind on the barren planet to study the Oasis — a mysterious zone shielded from solar radiation, magnetic storms, and somehow possessing its own atmosphere. Working alone proves impossible, so he does the logical thing: he clones himself. Then those clones clone more clones, each carrying a different life history and skill set. It's a setup that fits neatly into The Alters' central premise, and the expansion leans into it hard.
The DLC adds roughly 20 hours of gameplay — close to the length of the base game — alongside new mechanics including terraforming, an underground base, and a cryosleep aging system where your crew actually grows older while Jan hibernates. The scope is closer to a standalone follow-up than a content pack.

The Alters: Last Variable — new terraforming mechanics and an underground base expand the base game's survival systems.
What reviewers are saying
Praise centres on the mid-game, where the narrative and new mechanics click together in the same quietly unsettling way that made The Alters stand out. Base game credentials are strong: it won the DICE Award for Strategy/Simulation Game of the Year and earned a BAFTA nomination for Best Narrative.
The complaints are familiar territory for an expansion this ambitious. Some reviewers report minor technical issues — characters clipping into geometry, occasional frame-rate dips in the more detailed environments — though nothing game-breaking. More divisive is the ending. Both available conclusions reportedly leave key story threads unresolved, which has frustrated players who expected the philosophical payoff the base game promised.
At $19.99, this is premium pricing for a single narrative path, and players who haven't finished the base game's Jan Scientist route won't get much out of jumping in here. For those who have, per TechTimes, it delivers the same strange, morally loaded survival gameplay that earned The Alters its audience — ending frustrations and all.
