There are a number of naturally occuring hazards any intrepid Astroneer might encounter in their explorations - and most are fatal.
Many can be found across all the planets, while one is native to only one world. Some can be dealt with, others must simply be avoided.
Enviromental[edit | edit source]
Storms[edit | edit source]
Main Article: StormThe storm is a very notable hazard in Astroneer. It travels as a big cloud, making it possible that a player finds it on the first day, or as late as 20 days. It can kill the player, knock away unsecured resources, and even flip over certain vehicles.
Worms[edit | edit source]
The indigenous hazard on Radiated planets is a species of worm, a reference to Star-War's Sarlacc pit. It lays passively in the ground and wait for Astroneers to fall in. Travelling the surface, especially after dark, can prove to be a dangerous endeavor for the untrained astroneer as these inconspicuous predators lurk everywhere. Falling into a worm hole will mean instant death for an astroneer and complete absorption of its body, making all the Equipment stored in the backpack hard to recover. Worms will devour anything, from artifacts to resource stacks or even whole vehicles, making them an excellent base dumpster for unwanted materials. There is currently no method to dispose of them. Their bedrock nests can be excavated with a drill but the worm will not die from it. If you destroy the bedrock under them, you can recover your items and Research Item.
Hostile Flora[edit | edit source]
The planets of Astroneer teem with various types of flora. Hostile ones, however, are one of the constants during exploration in caverns. Hostile flora also spawn within the surface of Exotic, making them an even larger threat.
Exploders[edit | edit source]
Exploders look like another flora until you get near or disturb them. Upon filling in terrain at their base or digging them up, they will explode (hence their name). This explosion can be fatal if a player is standing too near its radius, but they can be safely dug up if done at a distance. They can be found everywhere in caves and always have organic Research Item at their root, making these a bountiful source of research early on. Large Exploders seem to produce energy spores, since the area around them always contains blobs of harvest-able power.
Acid Pots[edit | edit source]
These pumpkin shaped flora release green clouds of acidic gas that will follow Astroneers a short distance if they get too close. Like the Exploders, they also bear organic research item below them, and the area around them will contain harvest-able energy blobs. Similarly to Exploders and Spikers, they can be dug up to prevent them from producing gas.
Spikers[edit | edit source]
This giant tooth fungi is a danger toward the Player, and getting too near will cause them to release dangerous spikes around them which could kill the astroneer in two to three hits. Destroying the large one will provide player with two Seeds, while the small one only give one. Funny enough, the large Spiker can be safely jumped and stepped on due to the lack of spikes on the cap.
Cavern Lure[edit | edit source]
Cavern Lures are carnivorous plants that hang from cave ceilings and will ensnare and kill an astroneer if they manage to catch one with their dangling lures. They can be dispatched by digging around their bulb with the Terrain Tool. This will cause them to drop to the floor and explode, sometimes leaving behind a stack of organic or sometime batteries and tethers left by its previous victim.
- Cavern Lure once referred as "Red Dangler" during one of the stream
Tumbleweed[edit | edit source]
A formation of a giant lethal ball of spikes can be found blowing around in the wind on Arid planets. Getting hit by a single one is not fatal, but getting caught in the middle of a stampede can easily inflict multiple hits. If you are quick, you can get them with the Terrain Tool, and sometimes they will drop organic resource which conveys the fact that this object is indeed a flora.
