Outbound Mountains
The endgame biome — Rose Minerals (T5), Adamant Metal, Chrome Ore and the Summit Beacon. Cold, steep, and unforgiving until you have the Insulated Cabin module.

Mountains prep checklist
- Workshop T3 unlocked, Reinforced Pickaxe + Reinforced Axe crafted.
- Insulated Cabin module installed (12 Fibre + 6 Strong Weave + Hardened Metal).
- Suspension upgrade for the steep passes.
- At least 4 Bandages, 2 Thermal Tea, 1 Comfort Bed sleep before entering.
- Optional: Wind Turbine — solar drops to ~60 % in snow; Wind + Reactor Core covers the gap.
Rose Mineral route
All 6 nodes can be cleared in two in-game days if you park the van at the central peaks base camp. Mine 4 central nodes on day 1, sleep, push to the northern glacier face on day 2 for the last 2. You only need 4 Rose Minerals for the full endgame craft set (Reactor Core ×1 + Communicator ×2 + 1 spare).
Summit Beacon — ending trigger
The Summit Beacon sits at the highest point. Activating it with the Communicator triggers the ending choice. Which ending you get depends on prerequisites met before activation — see Chapter 4 Endings for the full branching table.
Common questions
What is the Mountains biome in Outbound?
The endgame biome — Tier 2–5. ~15 resources but the only place in the game with Rose Minerals (T5), and the densest source of Adamant Metal and Chrome Ore. The Summit Beacon at the top triggers the ending choice.
Do you need warm gear for the Mountains?
Yes — the Insulated Cabin module on the van is effectively mandatory. Cold drain is 12 Heat per 30 s on the high passes; without insulation you take HP damage through any night stay.
Where are the Rose Mineral nodes?
Six nodes total, all in the Mountains. Four on the central peaks, two on the northern glacial face. You need the Reinforced Pickaxe (Workshop T3) to mine them.
What is the Summit Beacon?
The peak structure that, when fed the Communicator, triggers the ending sequence. Reaching it requires Insulated Cabin + Reinforced tools + at least 1 Rose Mineral processed into a Phase Lens.
