The Alters: Last Variable: Days 4–6 Walkthrough – SAM Research Route

The clean Days 4-6 route in The Alters: Last Variable is to secure the Metals Outpost first, use that income to keep a Metal reserve, then run the Research Lab through Repair Kit, New Branching Procedure, and Analysis of Samples. Do not chase every anomaly as soon as it appears. Open the path to the Oasis, collect the required samples there, and return to the lab with your base able to handle repairs and equipment production.

Days 4-6 Priority Order

These days can stall if you treat exploration, research, and construction as separate jobs. They feed into one another: the Metals Outpost supports repairs and production, the Research Lab turns samples into progression, and the Oasis route supplies the materials needed for the next SAM objective.

• Establish steady Metal income through the Metals Outpost.
• Keep a reserve of Metal instead of immediately spending every delivery.
• Set up the Research Lab as soon as the base can support it.
• Prioritize Repair Kit research before committing resources to optional expansion.
• Continue into New Branching Procedure to advance the SAM research chain.
• Open the route toward the Oasis, investigate the required anomaly path, and gather samples.
• Bring the samples back for Analysis of Samples rather than leaving the research objective half-finished.

Day 4: Secure Metal Before Expanding the Research Queue

Your first important milestone is the Metals Outpost. Once it is operating, Metal becomes a dependable part of the base loop instead of a resource you have to interrupt every other task to find. That reliability matters more than a quick burst of construction, because Days 4-6 introduce enough research and infrastructure pressure that a single damaged system can derail the whole plan.

Keep Metal in Reserve

The common trap is treating fresh Metal income as permission to build everything immediately. Hold enough back to repair damaged infrastructure or produce emergency equipment. If a repair need appears after you have spent the reserve on a non-essential room or project, SAM progression stops while you rebuild your economy.

Use the first stable income to support the infrastructure that keeps the base functional, then let surplus Metal fund expansion. The goal is consistency: the base should still be able to repair, research, and produce equipment after an unexpected demand.

Day 4–5: Build the Research Lab Loop

With Metal income secured, make the Research Lab the center of the next stretch. The lab is where the SAM chain advances, and delaying it creates a false economy: you may have materials in storage, but no way to convert them into the next objective, equipment, or quest unlock.

Research Repair Kit First

Put Repair Kit at the front of the useful research queue. Repairs are the safety net for the base loop, especially while your Metal supply is still settling into a steady rhythm. Having this research handled means damage does not force you to abandon an Oasis run or postpone the next SAM step.

Follow With New Branching Procedure

Once Repair Kit research is complete or safely underway, move to New Branching Procedure. This is the progression project that keeps the SAM research route moving forward. Avoid filling the lab queue with side priorities ahead of it; the research chain is what opens the next set of objectives and gives your collected materials a purpose.

• First priority: enough Metal and base capacity to avoid a repair crisis.
• Second priority: Repair Kit research for infrastructure stability.
• Third priority: New Branching Procedure to continue SAM progression.
• Afterward: equipment production and other expansion projects that do not interrupt the sample-analysis route.

Day 5: Open the Oasis Route and Gather Samples

After the Research Lab is active and the SAM chain is moving, shift your field focus toward the Oasis. The important job here is collecting the samples required for Analysis of Samples. Do not treat the Oasis as a general scavenging detour. Your priority is the objective material that lets you finish the current research step.

Handle Anomalies in Objective Order

When several points of interest compete for attention, follow the route that opens access to the Oasis and leads to the required samples. This prevents a familiar slowdown: spending resources and time on nearby anomalies, then returning to the Research Lab without the one item needed to continue.

Once the samples are in hand, bring them back promptly. Carrying them while extending exploration only delays the research unlock and leaves the base waiting on the field team.

Day 6: Complete Analysis of Samples and Stabilize Production

Day 6 is where the route comes together. Submit the Oasis samples for Analysis of Samples, then use the Metal income and Repair Kit access to keep the base from falling behind while the next SAM results resolve. This analysis step is the bridge to the next quests and equipment progression, so it should take priority over cosmetic or optional construction.

Set Up Equipment Production Without Draining the Base

Only begin broader equipment production once the repair loop is covered. Metal has three competing uses during this stretch: maintaining infrastructure, supporting research-related needs, and producing useful equipment. The correct balance is simple: protect repairs first, preserve the Research Lab’s progress second, and spend the remainder on production.

If a specialist Alter path is available, the Geologist route is the practical early choice for this phase because resource acquisition supports every part of the plan. More reliable materials reduce the chance that research pauses halfway through or that a repair consumes the Metal intended for equipment.

What Usually Causes a Days 4–6 Stall

• Spending all Metal on expansion: leave a reserve for damaged infrastructure and Repair Kit production.
• Building the lab but delaying its key projects: start Repair Kit, then New Branching Procedure, before letting optional research occupy the route.
• Exploring anomalies without a sample objective: push toward Oasis access and take the samples needed for Analysis of Samples.
• Holding samples too long: return to the Research Lab once the required collection step is complete.
• Producing equipment too early: production is valuable, but only after the repair and research loop has enough Metal behind it.

Days 4–6 Checklist

• Metals Outpost reached and supplying steady Metal.
• Metal reserve held back for repairs or emergency equipment.
• Research Lab built and operating.
• Repair Kit research completed or actively progressing.
• New Branching Procedure placed next in the SAM research route.
• Oasis access opened.
• Required samples collected and submitted for Analysis of Samples.
• Equipment production added only after the base can sustain repairs and research.
