Season Contributions
You can track contribution metrics for the season by going to Season 2 Menu → Season Contributions. These rankings don’t directly grant rewards, but your R4/R5 leaders may use them to decide how to distribute loot rewards. Loot rewards are earned when your alliance captures territories and can be allocated by R4/R5 at their discretion.

Season 2 Goals
In the frozen expanse of the Polar Region, your biggest challenge is surviving the cold. Keep your base warm by using both your personal Furnace and the Alliance Furnace—temperatures drop sharply the closer you move toward the map’s center.
This season introduces temperature resistance and virus resistance, both boosted by upgrading your Furnace, making it your top priority from day one.
Rare Soil is another key resource. Once your alliance captures cities or dig sites in the Polar Region, they’ll produce Rare Soil over time. At the season’s end, alliances are ranked by the total Rare Soil collected—the higher the rank, the better the rewards.
Unlike Season 1, final city ownership doesn’t decide the rankings. Instead, every capture and holding action during Season 2 matters, as Rare Soil steadily accumulates throughout the season.

Last War Survival Season 2 Polar Storm Guide: The Map
You can use the toggle to enable the Thermal Map, which shows temperature levels across the entire region.
 |  |
Clicking on any point of the map will display the temperature for that specific location.
When the season starts, you and your alliance will be positioned together at the server’s outskirts, without control over any cities. To expand, you’ll need to reclaim these cities—but the rules have changed.
Elite Doom monsters have evolved into fierce polar creatures, and many zombies now require a strong virus resistance to be defeated.

Last War Survival Season 2 Polar Storm Guide: New Buildings
Season 2 introduces several new building types. Base-related buildings can only be constructed outside your base’s perimeter—the same zone used in Season 1. Some of these buildings are available from the very start of the season, while others will unlock as the season progresses.
Additionally, there are new alliance buildings exclusive to Season 2.
The Titanium Alloy Factory generates titanium alloy, an essential resource needed to upgrade your Furnace level.
The Titanium Alloy Factory can be upgraded to a maximum level of 30, independent of your Headquarters level. Upon reaching level 15 with the first factory, a new Titanium Alloy Factory becomes available, with each subsequent factory unlocking once the preceding one attains level 15. Additionally, one Titanium Alloy Factory is granted immediately upon obtaining the Season’s Weekly Pass.

High-Heat Furnace
This crucial new building lets you raise the temperature by consuming coal, while also boosting your virus resistance.
Leveling up this building increases your virus resistance, raises the furnace’s base activation temperature, and boosts the maximum heat achievable during overdrive mode when consuming extra coal per minute. It can be upgraded up to level 30 independently of your HQ level.
To raise your base temperature, simply turn on the High-Heat Furnace using its control panel. The panel includes an on/off toggle, an overdrive switch that consumes extra coal for increased heat, and options to automatically activate the furnace when a Blizzard hits. It’s designed to be straightforward and easy to manage.
Alliance Furnace
In addition to your personal High-Heat Furnace, the alliance gains access to an Alliance Furnace, allowing all members to collectively raise the temperature for everyone. From Day 1 of Season 2, alliances can place the Alliance Furnace build spot on the map in a Level 1 territory and begin repairing it to activate its use. This repair process works like constructing an outpost, requiring up to 20 reinforcements.

Cities
Cities and Dig Sites under your control generate Rare Soil, a vital resource for success in Season 2. The quantity of Rare Soil produced varies according to the level of each city or dig site.
 |  |
| City Level | Heat Provided (°C) |
|---|---|
| Level 1 | 5°C |
| Level 2 | 20°C |
| Level 3 | 30°C |
| Level 4 | 40°C |
| Level 5 | 50°C |
| Level 6 | 60°C |
Dig Sites
Dig Sites used to be key sources of coal, but now mutant beasts controlled by Emperor Boreas have seized them. Defeat these creatures to reclaim the sites and restart coal production.
Coal is essential for heating your base, making the capture of coal-producing Dig Sites a top priority for any alliance. The higher the Dig Site level, the more coal it generates.
Dig Sites generate coal and rare soil in amounts that vary by their level. Below is the detailed production rate for each level.
| Level | Coal Production (per hour) | Rare Soil Production (per hour) |
|---|---|---|
| Level 1 | 2,736 | 100 |
| Level 2 | 2,880 | 110 |
| Level 3 | 3,024 | 120 |
| Level 4 | 3,168 | 130 |
| Level 5 | 3,312 | 140 |
| Level 6 | 3,456 | 150 |
Last War Survival Season 2 Polar Storm Guide: Events
Rare Soil War
In this stage, Warzones are divided into two opposing factions—Rebels and Gendarmerie—adding a new layer of strategy and competition to the season.
 |  |
Reward Chest Goal
All Warzones must work collectively to capture a total of 10 Neutral Cities to achieve this objective.
Polar Dishes
Prepare delicious meals for the Siberian Husky by collecting the correct ingredients. This straightforward event involves gathering ingredients through daily task quests, then combining them to cook meals for Snowflake, the husky.
Rewards
Before diving into the mini-game, it’s worth noting the rewards to see why playing it well matters. Serving Snowflake a meal he likes earns you a golden reward box, while giving him a dish he dislikes will only grant a purple reward box.
Reactivate the Nuclear Furnace
 |
To help reactivate the Nuclear Furnace, send your troops by clicking on the furnace, then selecting the green truck icon. Choose your squad and confirm the deployment. Each send costs 5 stamina points, and you can contribute up to 10 times per day. Track your remaining attempts on the Event Page under the Warzone Info section, located just below the activation progress bar. Reach 100% progress to complete the goal.
 |  |
Kill the Glacieradon

They can’t be attacked while moving—wait until they reach a city. When attacking is possible, use your 5 daily hits wisely.
If a Glacieradon captures a city, it becomes neutral and gains protection.
Reinforce attacked cities to help damage the Glacieradon since individual hits are limited.
