Comparison

Frozen TundravsFrozen City

Both are biome 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	Frozen Tundra	Frozen City
In one line	Open, wind-scoured flatland — the most exposure-heavy biome.	Buried ruins — the highest-value salvage and the highest risk.
Key points	— Whiteout storms — Creeping chill with no shelter nearby — Exposure during long crossings — Scrap — Salvaged machinery — Basic insulation materials	— Hostile factions in deep districts — Structural collapse inside ruins — Frostbite during long indoor scavenging runs — Fragile pre-catastrophe technology — Generator parts — Advanced salvage

Which one you deal with first

Biome order is a route decision: you go where the salvage you need is, and you accept the exposure that comes with it. Plan the route around shelter spacing, not around distance.

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.
