In Helldivers 2, players will encounter a vast array of planets awaiting liberation, each presenting its own distinct environmental challenges. These challenges manifest as weather effects and planetary hazards, acting as mission modifiers that contribute to both the cinematic experience and the strategic depth of gameplay.
Here's a breakdown of all the weather effects and planetary hazards you may encounter in Helldivers 2, along with their effects and strategies for dealing with them. It's important to note that these environmental conditions are independent of difficulty levels, and planets can feature anywhere from zero to two modifiers simultaneously.

Acid Rain in Helldivers 2

Acid Storms
Planets experiencing intense heat conditions will often see occurrences of acid storms. While these storms may sound menacing, they primarily affect visibility, although not to the extent of sandstorms.
Blizzards
Blizzards in Helldivers 2 resemble rainstorms but involve massive snowstorms. These dense fog conditions moderately reduce visibility for both players and enemies. Additionally, the thick snow decreases mobility for all units.
The limited visibility can make it challenging to gauge the number of approaching enemies from a distance, increasing the risk of being overwhelmed or flanked if stationary. To counter this, it's essential to keep moving and stick close to teammates to avoid getting separated in the fog.
Pro Tip: Players should continuously monitor their mini-map radar for nearby enemy patrols during blizzards. Again, players can exploit their reduced visibility to stealthily navigate past them. Utilise Sentries effectively in Blizzards, as they don't rely on sight and can cover for you.
Extreme Cold
"Extreme Cold" in Helldivers 2 mirrors the challenges of Blizzards, featuring deep snow patches that significantly hinder mobility. While fog exists, it's not as dense as in Blizzards, allowing better visibility of distant enemies and structures against the clean, white terrain. To maximise this advantage, consider increasing your Render Distance, which doesn't noticeably affect FPS in Helldivers 2.
The Extreme-Cold weather effect slows down the firing rates of all your weapons. While the exact reduction percentage is unspecified, you'll observe a slight sluggishness in your automatic weapons. Mines are more challenging to spot in snowy conditions, so exercise caution when approaching Automaton-controlled fortifications.
Pro Tip: Energy-based (laser/beam) weapons take longer to overheat in these icy temperatures. The LAS-16 Sickle proves to be an excellent choice for freezing temperatures in Helldivers 2. Its heat sink takes longer to overheat, allowing you to maintain a higher overall damage output per second compared to other weapons.
Fire Tornadoes
Fire Tornadoes, a new planetary hazard in Helldivers 2, are currently active on the planet Hellmire and are expected to appear on other high-temperature planets soon.
These fiery twisters appear randomly across the map. Not just that, even their movement is randomised, and they leave behind trails of fire. If anyone is caught in a fire tornado or its fiery trail, they will get burned.
Pro Tip: Using a Stim is essential to stopping the lingering burn damage and healing yourself.
Intense Heat
Certain planets in Helldivers 2 feature arid climates with high temperatures, resulting in Intense Heat. Under these conditions, energy weapons overheat faster than usual, while other weapon types remain unaffected. Additionally, the sweltering environment accelerates stamina depletion, although stamina regeneration remains largely unchanged.
However, players should note that while some planets do not have high temperatures or heated weather conditions, they may still have certain areas with the intense heat effect, for instance, bug nests.
Pro Tip: The Stamina Enhancement Booster proves invaluable for dealing with environmental conditions characterised by high temperatures in Helldivers 2. This booster effectively boosts your overall stamina capacity, allowing you to better withstand the challenges posed by intense heat.
Ion Storms
Ion Storms in Helldivers 2 can be incredibly frustrating, as they temporarily disable all stratagems. These storms can occur multiple times during a mission and cover a large area, making it difficult to escape their effects. Players must strategize carefully and adapt to the situation, as running outside the storm's radius to enable Stratagems is a challenging task.
Meteor Storms
Meteor storms pose a significant challenge in Helldivers 2, resembling volcanic activity but occurring more frequently. During these storms, meteor rocks rain down from the skies, causing substantial damage and knocking down any players or enemies hit. It's essential to find cover quickly during a meteor storm, as they typically last for under a minute.
Pro tip: Players can watch the skies to confirm where the meteors are going to fall.
Rainstorms
Rainstorms in Helldivers 2 offer a captivating visual experience,.They significantly reduce visibility, especially at night. However, rainstorms do not impose any additional negative status effects. Contrary to rumours, there is no evidence to suggest that rainstorms negatively affect incendiary builds or flamethrowers.
Sandstorms
Sandstorms in Helldivers 2 cause similar disruptions when compared to Blizzards but with heightened difficulty. Visibility is severely limited for both allies and enemies, often restricted to just a few metres ahead. Additionally, mobility is significantly impaired for all units, further complicating navigation and combat scenarios.
Thick Fog
Thick Fog is an environmental condition in which dense fog blankets the environment, reducing visibility for both enemies and allies. This weather effect often accompanies other environmental conditions like Rainstorms and Blizzards, adding an extra layer of challenge to missions.
Pro tip: If you see dense fog with a musky green tint, it's probably the result of a Spore Spewer rather than the weather. Look for a giant, glowing mushroom within the fog and destroy it to dissipate the mist and improve visibility.
Tremors
Tremors, akin to earthquakes, are a newly introduced hazard in Helldivers 2, typically occurring on planets with Intense Heat or Volcanic Activity. Unfortunately, there's no way to avoid them, but the silver lining is that they only last for a brief period. When caught in a tremor, both players and enemies will experience temporary slowing effects and be unable to sprint.
Pro Tip: You can dive to evade danger during tremors.
Volcanic Activity
Volcanic activity, a hazard prevalent on hot planets in Helldivers 2, introduces a perilous environment with the eruption of volcanoes. These eruptions hurl massive rocks of molten magma across the map, scorching the land in their wake. Should a player come into contact with these burning rocks, it spells instant death, while being ensnared in the fiery areas results in being engulfed in flames.
Pro Tip: Similar to meteor storms, players can monitor the skies to anticipate the trajectory of the burning rocks and avoid their deadly impact.
So, currently, these are all the Planetary Hazards and Environmental Conditions that exist in Helldivers along with some advice on how to tackle them. We will update you as the game receives further changes and adjustments.
