The Alters Last Variable

The Alters: Last Variable is a DLC that follows the ending in which Jan Scientist stays on the planet. With an estimated playtime of 20 hours, it follows his effort to lead a team of new specialists, all assembled by and from himself, to investigate the Oasis phenomenon. The crew’s scientific focus may not align with the goals of Jan Geologist, Biologist, Chemist or Physicist.

Investigate the Oasis

The Oasis is a lush paradise that should not exist. You terraform nine arenas to unlock it and search the landscape for answers, while earthquakes and radiation complicate each research step.

Survive planetary cycles

Years-long cycles bring scorching sunrises that force the crew underground. You build a functional base in varied soils, construct new components and research modules such as the Cryosleep Chamber, which lets you wait to see the long-term effects of your scientific work. Increasingly vicious cycles still wear down the crew’s readiness to work, even during cryosleep.

Each planetary cooldown gives you a brief opportunity to explore a surface that has changed dramatically. Terraformed terrain opens new building options, contains pickables that provide bonuses and yields new resources for extracting and refining research-essential technology. Specialised structures let you transform, combine and amplify the resources you gather.

Work and ageing

Field Labs add assignments that let the alters continue their work while you cryosleep. The crew’s outlook may change as its members face the vulnerability of ageing.
