Season II: Polar Storm

Season Menu
In the Season menu, you will find all the important information and functions for the current season. Here you can always see what activities are currently available and view the corresponding rankings.
Overview
Season 2 "Polar Storm" transports all players to a frozen polar region ruled by the tyrant Emperor Boreas. Additional to the known virus resistance from Season 1, Season 2 revolves around temperature management and the fight against the freezing cold.
The season lasts 8 weeks and introduces new buildings, resources, and mechanics. The main goal for alliances is to collect Rare Soil, which determines the ranking placement.
Key changes from Season 1:
- Cold zones instead of virus infections as the central environmental hazard
- Rare Soil accumulation as the main goal instead of city ownership
New Enemies
Season 2 introduces new enemy types:
Polar Zombies
The single zombies on the map are now "Polar Zombies." Like in Season 1, they feature a distinct troops type and can be killed for some minor first kill rewards.
Doom Elites
Doom Elites work like Season 1. They offer substantial rewards on their first kill, but higher levels feature higher resistances, which means you have to build up resistances before being able to tackle higher levels. They are the main source of
Coal early on.
Mutated Bear
Mutated Bears feature high resistances and suggested power, and have to be defeated to capture a Dig Site. Make sure you have substantial power and resistances.
New Resources
Season 2 introduces two new main resources:
Coal
Coal is the most important resource of the season. It is needed to power furnaces, upgrade buildings, and support alliance structures.
You can obtain Coal by:
- Defeating Doom Walkers (first kill daily) and Doom Elites (first kill per level)
- Capturing and controlling dig sites (harvested
Coal can be acquired in the Alliance Menu -> Alliance City) - Special daily Radar Missions
- Season Goals and Milestones (look up the seaons menu)
- City gate visitors
Titanium Alloy
Titanium Alloy is needed for upgrading furnaces and military buildings.
You can obtain Titanium Alloy by:
- Titanium Alloy Factories (720 per hour per level)
- City first capture rewards
- Defeating Doom Walkers (first kill daily) and Doom Elites (first kill per level)
Temperature Mechanics
Temperature is the central element in Season 2. The map has different temperature zones:
- Map Edge: approx. -15°C (relatively warm)
- Map Center: down to -80°C (extremely cold)
When zooming out on the World Map, you can switch to a Themal Map view to see the temperature zones more clearly. Clicking on a square on the World Map will also reveal the temperature at that location.
Temperature Effects
| Temperature | Effect |
|---|---|
| Above 40°C | Base starts to burn on a 5-minute cooldown |
| Above 0°C | Normal production, full functionality |
| Below 0°C | Reduced resource production |
| Below -20°C | 5-minute countdown until freezing |
| Frozen | No advanced teleport, no rallies, severely reduced production |
Furnaces
There are three way to heat up your base:
- Switch on your personal High-Heat Furnace (consumes
Coal) - Stay within the heat zone of an Alliance Furnace (alliance members need to donate coal to power it)
- Heat up alliance members with your spy planes (consumes coal)
Temperature Management Tips
You can see your base temperature and all affecting factors by clicking the temperature icon on the left of your screen. This is the temperature your base always will come back to.
- Try to keep your base temperature above 0°C, but always above -20°C to avoid freezing.
- Only use Overheat mode during blizzards or when advancing into colder zones
- Overheat mode consumes 4x as much coal - remember to turn it off
- Stay within the Alliance Furnace's heat zone for additional warmth
It's often beneficial to heat up your base temporarily for certain activities like attacking the code boss or collecting resources.
Blizzards
Blizzards are special events that drop the temperature drastically for a limited time. There are extra rewards for the alliance and players who manage to keep their bases from freezing during these events.
Your High-Heat Furnace has the option to automatically turn on during Blizzards, but keep in mind that you need sufficient
Coal and that you need to manually turn it off afterwards.
Buildings
Season 2 introduces new buildings:
High-Heat Furnace
The most important building of the season. Upgrades increase:
- Base temperature
- Virus resistance
- Production bonuses
Requires:
Titanium Alloy for upgrades,
Coal for operation.
There a normal and an overdrive mode. Use overdrive only during Blizzards or when venturing into colder zones, as it consumes 4x the coal.
Early on, you're stuck in the loop of killing Doom Elites and upgrading the furnace to build up enough resistance to be able to kill higher level elites for more rewards that eventually lead to further upgrades of the furnace.
Titanium Alloy Factory
Continuously produces Titanium Alloy.
Upgrade Tip: Build all factories evenly up to level 15 before upgrading them together. This maximizes efficiency relative to coal consumption.
Alliance Furnace
A shared alliance building that provides warmth to all members within range.
- Powered by coal donations from members
- Higher levels = larger heat zone
- Position can be strategically chosen for city defense or Rare Soil wars
World Map
Everything on the world map can freeze at -20°C and players must break the ice before interacting with the object. This affects Doom Elites, cities or other players.
In that case a frozen meter indicates how much ice is left. You can break the ice by either heating up the area or sending troops using the pickaxe symbol. One "attack" removes 1000 ice points.
Scattered Supplies
Throughout the map, you can find scattered supply crates that contain minor rewards and reveal themselves when the area around them is heated up above 0°C or capturing the city in the area. You can see all locations here.
Locations can only be revealed and looted once per server. So it might make sense to keep track of the looted ones. All shared supplies can be found in the Season Menu under Supply Collection.
Especially useful to reveal Supplies is the Season Profession Skill Firebomb, which raises the temperature of a 9x9 area by 15° per level. Just make sure you heat up the area sufficiently to reveal the supply crate.
Territorial Conquests
Territorial conquest is similar to Season 1 in that you need to start on a Level 1 "Stronghold" (now called Dig Site) and conquer adjacent areas. You can only ever hold four Dig Sites and six Cities at the same time and conquer a maximum of two Dig Sites and two Cities per day.
Dig Sites continuously produce Coal for all members of the alliance (claimable in the Alliance Menu -> Alliance City) and all territories generate
Rare Soil.
Important Information:
- Maximum 4 dig sites per alliance (reduced from 6)
- Guarded by mutant beasts (Guerilla, Mammoth, Bear) that require substantial resistance and power to defeat.
- Each boss type has different weaknesses (Missile, Aircraft, Tank)
Rare Soil & Rankings
Rare Soil is the key resource for alliance ranking.
- Produced by controlled cities and dig sites
- Total amount of Rare Soil determines alliance placement
- Unlike Season 1, it's not about final city ownership but accumulated amount
Rare Soil War
The central PvP event of the season where alliances fight over dig sites and cities.
Phases:
- Announcement phase
- Preparation phase
- War phase
- Evaluation
Professions
The familiar professions from Season 1 remain, but the season skills have been adjusted to fit the new season mechanics. They offer various advantages in leveling up, and temperature management. Two skills worth noting are Double Exchange which can swap
Coal and
Titanium Alloy with a 1:2 ratio, and Firebomb, which raises the temperature of a 9x9 area by 15° per level and is quite useful for revealing Scattered Supplies.
Engineer
Especially useful in Season 2:
- Faster building and research
- Bonus on resource production
- Support for allies
War Leader
For active PvP players:
- Combat bonuses
- Faster expansion
- Strengthened troops
