Helldivers 2 Guide: All environmental conditions and how they affect gameplay

Helldivers 2 has a variety of planets to liberate, and each one has its own set of environmental conditions to overcome. From weather effects to planetary hazards that serve as mission modifiers. Not only do they add a cinematic feel, but they also provide unique buffs and debuffs.

Thick fog, for example, will make it difficult to find that elusive rock with superuranium. Sandstorms will interfere with your ability to see. Ion storms will disrupt stratagems. So before going on a mission, always check the planet’s environmental challenges from your ship. This will give you an idea of ​​what weapon to equip.

Below is a list of all the weather effects and planetary hazards in Helldivers 2 , along with what they do and how to deal with them. Please note that environmental conditions are not tied to difficulty levels. Planets can have zero to two environmental modifiers at a time.

Acid storms

On planets with Intense Heat there will always be a chance of Acid Storms occurring. They sound dangerous, but they only reduce your visibility – not as much as Sandstorms.


Blizzards are similar to Rains, except you have to deal with massive snowstorms. Thick fog moderately reduces visibility for both you and your enemies. In addition, deep snow reduces the mobility of all units.

Due to reduced visibility, it is difficult to understand how many enemies are approaching from afar. There is a high probability of being outnumbered, and enemies can also outflank you. Make sure you keep moving and stay as close to your teammates as possible. Don’t lose them in the fog.

Monitor the mini-map radar for nearby enemy patrols. Take advantage of their reduced visibility and sneak past them. However, do not forget that not all enemies rely on vision.

Extreme cold

This environmental condition is much like Blizzards in Helldivers 2 . There are deep areas of snow that greatly reduce mobility. There is also fog, but not as thick as during Blizzards. You can usually see distant enemies and buildings thanks to the clear white terrain. It’s worth increasing the draw distance to take advantage of the improved visibility. Luckily, this doesn’t slow down the frame rate at all.

Mines are harder to spot in the snow. Be careful when approaching fortifications controlled by Automatons. Large bases always have minefields outside the walls.

Unlike Blizzards, Extreme Cold’s weather effect reduces the rate of fire of all your weapons in Helldivers 2 . The exact reduction percentage is unknown, but you will notice a slight sluggishness in automatic weapons. On the other hand, energy (laser/beam) weapons take longer to overheat at low temperatures.

The new LAS-16 Sickle is an excellent weapon for cold temperatures. You will be able to increase your overall damage per second.

Fire tornadoes

Fire tornadoes are one of the new planetary hazards in Helldivers 2 . They are currently active on the planet Hellmire, but should begin to appear on other planets with high temperatures.

Fire Tornadoes, as the name suggests, are firestorms that spawn randomly across the map. They always move randomly, leaving a trail of fire behind them. Getting caught in a Fire Tornado or its trail of fire will cause you to burn. You need to use Steam to stop the burning.

Intense heat

Some planets are arid and have high temperatures. The intense heat causes all energy weapons to overheat faster than normal. However, the rest of the weapons remain untouched. Hot environmental conditions also drain your stamina faster in Helldivers 2 , but stamina regeneration remains largely untouched.

Note that some planets may not have high temperatures, but some areas (near bug nests) may receive an Intense Heat warning. You can move out of the area to remove the stamina debuff.

The Stamina Booster is great for high-temperature environments.

Ion storms

Ion storms are one of the most annoying weather effects. They temporarily silence all your stratagems in Helldivers 2 . This can happen multiple times during the same mission. Note that Ion Storms occur over a large area, so trying to run outside their radius to trigger your Stratagems is a difficult task.

Meteor showers

Meteor showers are perhaps the most challenging planetary hazard in Helldivers 2 . They are similar to Volcanic Activity, but are much more common. During a Meteor Storm, meteorites will rain down from the sky. Players (or enemies) caught by the meteorite will be knocked down and take heavy damage. Be sure to find some cover because the Meteor Shower lasts less than a minute.


Rainfall is one of the most beautiful weather effects you’ll encounter in Helldivers 2 . They significantly reduce visibility, especially at night. However, there are no other negative effects of the condition to worry about.


Sandstorms have the same environmental conditions as Blizzards, but are much more complex. They significantly reduce visibility for all friendly and enemy units. You can barely see beyond a few meters. To make matters worse, mobility is also greatly reduced for everyone.

Thick fog

Veil of Fog reduces visibility for all enemies and allies. It is more of an associated environmental condition that will sometimes be part of other weather effects such as Rain and Blizzards.

If the thick fog is a dull green color, you are dealing with the Spore Bearer and not the weather. Find the giant glowing mushroom inside the fog and destroy it to clear the fog. Please note that the mushroom protects many enemies.


Tremors are essentially earthquakes that can occur randomly in a specific area and are often found on planets with Intense Heat or Volcanic Activity. Players and enemies caught in the earthquake will be temporarily slowed. You won’t be able to run, but you will be able to jump to dodge enemies.

Fortunately, the tremors only last a few seconds.

The tremors can stun enemies. Instead of trying to escape, it may be better to take a defensive position and finish off heavily armored enemies such as Stormtroopers.

Volcanic activity

Volcanic activity is another planetary hazard that can occur on hot planets in Helldivers 2 . If you spot volcanoes in the distance, there’s a good chance they’ll erupt soon and scatter giant chunks of magma across the map. Volcanic storms leave the earth scorched. Hitting a burning rock will kill you, and getting into a burning area will cause a fire.

Similar to Meteor Storms, you can watch the sky to determine where burning rocks will fall.

For now, these are all the effects that can be found in the game, but there is no doubt that as Helldivers 2 develops , new ones will appear.
