Comparison

Base BuildingvsCo-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.

Axis	Base Building	Co-op Survival
In one line	A network of shelters, not one mega-base.	Co-op does not make the world easier. It makes it less lonely.
Key points	— Early game: restore ruined perimeters, do not build exterior walls. — Mid game: engineered outposts with centralised thermal cores. — Late game: communal hubs sized for up to four players.	— 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.
