The Alters Last Variable Review After 100 Percent
Achieving 100 percent completion in the expansion reveals a masterfully crafted sci-fi survival loop. Unlike the base game, this campaign demands tighter resource management, stricter cycle planning, and deeper ethical engagement with your cloned crew. By analyzing The Alters Last Variable review after 100 percent, players can optimize their routing, avoid catastrophic bottlenecks, and witness every narrative conclusion.
| Feature | Details | Game Impact |
|---|---|---|
| Story Length | Approximately 20 hours | High replayability via branch saves |
| New Alters | 4 Specialist types | Controls production and research speed |
| New Arenas | 9 Terraforming zones | Expands resource lines and hazards |
| Achievements | 7 Additions (210 Gamerscore) | Rewards complete narrative exploration |
Reaching 100 percent completion requires finishing all four specialist Alter storylines, unlocking both final endings, and starting production on all advanced materials. Keeping a manual save before activating the final generator saves hours of backtracking.
Specialist Alters and Best Work Assignments
Managing your scientific crew is the core pillar of survival. Creating Alters in the correct order prevents early-game resource starvation and ensures your research moves faster than the planetary cycle deadlines.
S-Tier: Jan Geologist
- Creation Priority: 1st
- Efficiency: 50% faster Metal mining
- Best Assignment: Early Metal extraction and geology research
A-Tier: Jan Physicist
- Creation Priority: 2nd
- Efficiency: 50% faster base maintenance and Workshop crafting
- Best Assignment: Workshop queues and Splitter research
A-Tier: Jan Chemist
- Creation Priority: 3rd
- Efficiency: 50% faster refining; 37.5% faster Field Lab research
- Best Assignment: Field Labs and rare-resource processing
A-Tier: Jan Biologist
- Creation Priority: 4th
- Efficiency: 100% Greenhouse speed; 8x faster Infirmary healing
- Best Assignment: Crop growth, medical recovery, and biological research
| Specialist | Scientific Specialty | Key Research Project | Field Lab Suitability |
|---|---|---|---|
| Geologist | Deposits, terrain barriers, anomalies | Phased Rapidium | Keep at base until late game |
| Physicist | Base networks, processing, instruments | Splitter, scanner | Send after crafting spare parts |
| Chemist | Refined materials, food, samples | Field Laboratory | Excellent early Field Lab candidate |
| Biologist | Crop growth, medical, ecosystem | Uses for Slime | Keep at base if injuries are high |
When an Alter is assigned to an external Field Laboratory, they stop contributing to daily base maintenance and production. Complete their personal conversations and urgent workshop tasks before sending them out.
Underground Base and Cryosleep Cycle Guide
Your underground base must be prepared to survive the planet's years-long hot phases. Each cool phase acts as a frantic preparation window where you must secure resources, maintain power grids, and stockpiles Organics before entering cryosleep.
Repair the Core
Build a Repair Kit in the Workshop for 10 Metals, repair the damaged Research Lab, and research the New Branching Procedure.
Construct the Cryosleep Chamber
Reserve 50 Metals and 65 Rapidium to build the chamber before the 14-day Forced Dormancy deadline.
Secure Organics Reserves
Stockpile 50 Organics for each person entering cryosleep (e.g., 150 Organics for Jan and two Alters) to prevent waking up to critical shortages.
Run the Final-Day Checklist
Dismantle surface structures to recoup parts, heal injuries, feed the crew, and assign your chosen Alter to the Field Lab before sleeping.
| Resource | Primary Use | Early-Game Bottleneck Solution |
|---|---|---|
| Metals | Base modules, Repair Kits, outposts | Build Metals Outpost south of base on Day 1 |
| Rapidium | Alter creation, advanced modules | Extend power pylons to southern deposits |
| Organics | Food, cryosleep buffer, modules | Establish Organics Outpost behind the base |
| Proxilium | Tier II Terraformers, Splitters | Build Proxilium Tanks during Cycle 3 |
Entering cryosleep with low crew morale, untreated injuries, or high radiation levels can trigger an Alter Revolt upon waking. Always use the final evening of a cycle to heal and feed your team.
Terraforming Arenas and Resource Priorities
The expansion features nine distinct arenas centered around the Oasis. Activating Terraformers changes pathways, exposes rare materials, and unlocks new stages of the research tree.
| Arena | Terraformer Tier | Key Pickables | Primary Role & Strategy |
|---|---|---|---|
| Oasis | Reference Biome | 3 Electric Algae | Collect all opening samples on Day 3 |
| Rocky Valley | Terraformer I | 3 Polymer Gas, 1 Obsidian | Location of the first Field Lab site |
| Base | Terraformer I | 4 Technology Debris | Rebuild resource network first after waking |
| Narrow Cliff | Terraformer I | 1 Electric Algae, 2 Gas | Secure the Enriched Metal Outpost early |
| Misty Gorge | Terraformer II | 2 Obsidian, 2 Debris | Midgame research hub; location of Field Lab 2 |
| Volcano | Terraformer II | 4 Obsidian, 1 Mushroom | Mineral extraction zone for Megafluid lines |
| Remains Hollow | Terraformer II | 3 Technology Debris | Search ruined base for Chemist story items |
| Waterfall | Terraformer III | 2 Algae, 1 Mushroom | Late-game biological sample expedition site |
| Far Hill | Terraformer III | 2 Mushrooms, 1 Obsidian | Location of the third Field Lab; high radiation |
Terraforming triggers defensive planetary reactions. Expect earthquakes and radiation waves to damage base modules. Keep a surplus of Metals and Repair Kits in your inventory to handle emergency repairs.
Endings, Missable Content, and Achievement Checklist
Reaching 100 percent completion requires experiencing both narrative conclusions and unlocking all seven expansion achievements. The defining narrative split occurs during the final conversation with JanBot.
Ending 1: Create a Successor
- Requirements: Choose to create a successor during the final JanBot exchange.
- Outcome: Jan Scientist's legacy continues as a new Alter and JanBot carry on the endless research.
- Theme: Prioritizes scientific discovery over personal closure.
Ending 2: Break the Cycle
- Requirements: Choose to stop the succession model during the final conversation.
- Outcome: Jan rejects creating another life to carry the research burden, accepting mortality and restraint.
- Theme: Prioritizes ethical responsibility and closure.
Expansion Achievement Checklist:
- Space Gardener: Place the first Terraformer.
- Mastering Rapidium: Start production of Phased Rapidium.
- Mix and match: Start production of Proxylium.
- Substance Genius: Start production of Megafluid.
- Wait, you can do that?: Create the same Alter for a second time.
- Caring after all: Complete all four Scientist's Alters' storylines.
- The reason I stayed: Complete the Last Variable campaign.
The game creates an autosave right before the final JanBot conversation. After completing the campaign and viewing your first ending, reload this save to immediately trigger the second ending and secure your final completion achievements.
Frequently Asked Questions
Q: Does The Alters Last Variable review after 100 percent show that you need a base game save?
No. The expansion runs as a completely separate campaign from the main menu and does not require an existing completed save file from the base game.
Q: Can you miss any achievements during a single playthrough?
Yes. 'Caring after all' requires completing all four specialist Alter storylines, and 'Wait, you can do that?' requires cloning the same Alter type twice. Keep manual saves before assigning Alters permanently to Field Labs.
Q: What is the consequence of sending an Alter to a Field Lab?
The assigned Alter will age visibly across cycles as they work outside while Jan Scientist sleeps. They will also stop contributing to your underground base's daily production and maintenance.
Q: How do you avoid running out of Organics before cryosleep?
Set up an automated Organics Outpost behind your base early in the cycle, and treat the final day as a strict gathering phase instead of starting long research projects.
