Shelf-style database

Systems should answer what problem they remove, not just what they are called.

Use this shelf when the topic is a named system and you need the shortest path to its value, timing, and next upgrade decision.

Best fit

Open this page when the system name is already known, but the value, timing, or upgrade order still feels unclear.

System entries

Use the system row that matches the friction you keep repeating.

System Main value When it matters most Best next page
Scanner Room Reduces repeated search time When route shape already works but scouting still wastes trips Scanner decision
Storage support Makes returns and crafting cleaner When the base works, but hauling still turns into clutter Storage upgrades
Base power Keeps utility from collapsing mid-run When the base exists but still feels fragile or annoying Base power
Vehicle support Turns longer routes into reliable travel When home flow is stable enough that travel is now the real blocker Vehicle upgrades

System shelf

Use this page for named system lookups once the blocker is clearly scanner, power, storage, or vehicle support.

Upgrade Planner

Use this when several systems all sound useful and you need the one that fixes the repeated failure first.

Base Building Center

Use this when the system question still depends on site choice, layout, or cleanup order.

System shelf notes

What this system shelf should answer before the player spends materials.

System pages are only useful when they show what problem the system removes. A shelf that only names the system without the effect still leaves the player guessing.

Quick answer
  • Spend on the system that fixes the repeated failure first.
  • Check whether the base or vehicle is already doing enough work.
  • Use the smallest upgrade that solves the bottleneck.
Common mistakes
  • Spending materials on a system before knowing what broke.
  • Upgrading for comfort instead of for removal of a real problem.
  • Letting multiple systems compete for the same batch without a priority order.

System value check

What the shelf should decide after the system name is already known.

The system shelf should help the reader decide whether the system solves the current blocker now, whether a different support page should come first, and what the next upgrade step should be if the system is worth building.

Quick answer
  • Spend on the system that removes the biggest repeated failure.
  • Check whether base or vehicle support would solve more of the problem first.
  • Keep the system choice tied to the current run, not to a generic build list.
Common mistakes
  • Choosing systems by prestige instead of usefulness.
  • Buying support tools before the core failure is identified.
  • Letting one upgrade batch try to fix every problem at once.

Systems depth

What the systems shelf should explain before the reader uses it.

System pages are strongest when they name the problem they solve: storage, power, scanning, vehicles, or base timing. That keeps the shelf from becoming a list of labels without practical value.

Quick answer
  • State the problem the system removes before the feature name.
  • Point readers to the page that shows how the system changes a run.
  • Keep the shelf focused on comparison and handoff, not long background.
Common mistakes
  • Explaining a system without saying why it matters now.
  • Letting the page become a loose glossary entry.
  • Forgetting to point toward the base or upgrade page if the system is really a planning choice.

System shelf rule

Every system entry should say what friction it removes.

If a page cannot connect the system to a real blocker, it is not helping the reader yet. The shelf should translate feature names into practical run changes.

Storage

Use when cleanup trips are the problem.

Power

Use when the base or tool chain cannot stay online.

Scanning

Use when the player needs a better information loop.
