This is an ultimate walkthrough for The Alters – Last Variable. This guide contains detailed information on everything a player needs to do to reach every main objective in this expansion pack while investigating mysterious occurrences that take place in the Oasis. This guide tells a player how to manage the growing number of Alters, and how to use new features for building underground bases and modifying the planet’s surface. Everything a player might need to solve any logic puzzle, figure out the right narrative sequence, or survive against new environmental challenges can be found here.
Part 1
In part 1 of the walkthrough, following the death of the Old Scientist, Jan must restore the underground base, uncover the secrets of the Quantum Computer, and prepare for long-term survival beneath the planet’s surface. As he repairs the Research Lab, gathers vital resources, creates his first new Alter, and investigates the mysterious Oasis, he gradually uncovers evidence of an unknown force protecting the region, leading to the construction of a SAM to further analyze the anomaly.
Part 2
In this part of the walkthrough, you’ll focus on expanding both your base and workforce while securing the resources needed for the next stage of the story. After creating the Geologist Alter, you’ll establish new mining operations, clear blocked paths with Drill Cartridges, and continue upgrading your base with essential rooms like a Dormitory and Refinery. As your research progresses, you’ll push further into the map to locate and harvest Rapidium by building a network of pylons to a newly discovered oasis. Before the chapter ends, a discussion with the Geologist introduces zero-gravity elevators and sets up the creation of another Alter, with the Chemist being a strong option for your growing team.
Part 3
In this part of the walkthrough, you’ll continue expanding your base while introducing the Physicist Alter and progressing several key research projects. Your main objective is to gather the resources needed to build the SAM, perform its preliminary analysis, and use the results to unlock new objectives, including Chasing Anomalies and Advanced Infrastructure. Along the way, you’ll establish a Research Station, investigate anomalies to collect valuable samples, begin researching Phased Rapidium and Identity Replication, and assist the Physicist with his personal quest. By the end of this section, you’ll be producing essential new equipment, including the Extractor, Cathy’s Modulator, and a Phaser, setting your colony up for the challenges ahead.
Part 4
In this part of the walkthrough, you’ll juggle several important story quests while upgrading your base to handle the growing challenges ahead. You’ll help the Geologist continue his anomaly research by collecting rare Prism and Time Dilation samples, while also resolving the Physicist’s troubled relationship with Cathy by completing his personal quest. Along the way, you’ll construct essential infrastructure such as the Phaser, Extractor, pipelines, an Infirmary, and a Phased Rapidium Tank, allowing you to begin producing Phased Rapidium. As the chapter comes to a close, you’ll unlock The Great Gardener quest by setting up the new extraction network and begin researching Terraforming, all while preparing your colony for an incoming Magnetic Storm.
