Warmth & SheltervsCo-op Survival

Both are system entries in the same Permafrost reference set. The table below puts them on the same axes — and the last row is the one that matters: what neither of them can tell you until the build ships.

AxisWarmth & ShelterCo-op Survival
In one lineWarmth is the currency. Shelters are the banks.Co-op does not make the world easier. It makes it less lonely.
Key points
  • — Restore abandoned shelters instead of building walls from scratch — far cheaper in scarce materials.
  • — Centralise generators deep inside the shelter; perimeter placement bleeds heat.
  • — Build "warm rooms" to wait out whiteouts instead of burning fuel continuously.
  • — Split roles by resource stream, not by task order.
  • — Size communal hubs for the actual player count — overbuilding wastes heat.
  • — Loot sharing needs a rule before the run starts, not during it.

Which one you deal with first

System order is a priority decision: fix the meter that is killing you fastest, not the one that is easiest to optimise.

Both entries share the same rule on this site: no number appears unless it is published or measured. The “unmeasured” row is identical in spirit across every comparison page — it exists so you can tell the difference between a wiki that knows and a wiki that guesses.
