One-line summary
Polar Storm — a frozen map where season-only temperature management gates every action, and Rare Soil ranking/war plus Scattered Supplies are the core. About 8 weeks.
Core systems
- Temperature — the season’s premise. Base temperature shifts with location, furnaces, alliance buildings, city heat, and blizzards. The polar center is colder. Below −20°C you can’t rally or teleport — always check temperature before advancing. Supplies only appear when you heat an area to 0°C or higher.
- Rare Soil. Captured cities/dig sites produce Rare Soil over time, and alliances are ranked by total Rare Soil at season end — holding territory is the ranking.
- Coal · Titanium Alloy · Alliance Furnace. Manage coal for heat, and position the alliance furnace to carve warm advance routes.
- Scattered Supplies. Season-long; reveal by heating to 0°C+. Rewards: weapon shards, universal shards, alliance points, resources. Coordinates are identical across servers in your season group.
- Violet SSR→UR promotion available this season.
Priorities
- Stay above the −20°C safety line so you’re never action-locked.
- Hold territory to accumulate Rare Soil — the ranking core.
- One main carry to EW Lv20 (Murphy/Carlie/Swift per your line).
- Keep collecting Scattered Supplies — shards feed your carry.
- Black Market at season end.
Week-by-week
Week 1 — Open + temperature + Murphy EW
- Adapt to temperature (furnaces/city heat), gather early supplies by heating to 0°C+. Murphy EW opens (tank).
Week 2 — Holdings + Rare Soil setup
- Capture cities/dig sites to start Rare Soil production; push the alliance furnace forward to keep holdings warm.
Week 3 — Faction choice + Carlie EW
- Choose a faction (Rebels vs Gendarmerie). Carlie EW opens (air).
Week 4 — Rare Soil War (the hard part)
- Rare Soil Wars begin, with blizzards overlapping — temperature is trickiest here. Check temperature/shields/rally before advancing.
Week 5 — Lock in ranking
- Defend holdings to protect accumulation. No solo dives — follow alliance calls.
Week 6 — Swift EW + finish build
- Swift EW opens (missile), completing the season’s 3 EWs. Finish your main’s EW Lv20.
Week 7–8 — Final race + Black Market
- Final Rare Soil ranking. After it ends, top up shards in the Black Market.
Scattered Supplies — coordinates
Supplies hide in city squares and reveal only when heated to 0°C+. Up to 5 rewards/day. Coordinates are identical across servers in your season group.
- Tool: Season Coordinate Map (beta). Verified coordinates are filled via screenshots/crowdsourcing (no copying other sites’ coordinate DBs).
Post-season — Black Market
EW shard choice chest (8 daily refreshes, ~150 shards/season) → decorations → free items first. See the season index.
Caution
Advance ignoring temperature and you’ll hit a −20°C zone where rallies are blocked — combat becomes impossible. Always check temperature → shields → rally. Rare Soil is about holding, so take territory you can defend rather than overreaching.
