There are a number of naturally occurring hazards any intrepid Astroneer might encounter in their explorations - and most are potentially fatal.
Many can be found across all the planets, while one is native to only one world. Some can be dealt with, while others must simply be avoided. Offensive flora will respond to the player on foot but not seated in a vehicle.
Defensive Flora[edit | edit source]
Defensive Flora only harms the players when walking near, or jumping onto the plant, typically knocking back the player and causing initial damage. If the player gets knocked too high, the player may take fall damage and die. Defensive flora has a chance to drop a seed when dug up, allowing it to be replanted to gain even more Seeds, Research Samples or Research Items at the roots.
Offensive Flora[edit | edit source]
Offensive Flora will harm players from a longer range than defensive flora will, and are often more deadly, spewing clouds of acid or shooting exploding projectiles.
Removed Hazards[edit | edit source]
Worm Pits[edit | edit source]
Worm Pits were a hazard on the original Radiated planet. They sat on the surface, awaiting players to unknowingly fall in, leading to instant death. Hard, black terrain sat at the base of the pits, making digging around them difficult without a Drill. Removing the soil around the base would leave the pit hovering in the air, but allow the player to gather any items that may have fallen in.
Worm Pits were removed in Patch 1.0.
Storms[edit | edit source]
Storms were a major hazard in the game. They were a giant, roaming dust storm, that could be heard from far away. When reaching the player, storms would be deadly if shelter wasn't found, with cubes flinging at the player until one made contact. Items and vehicles could be blown away or moved due to the high winds.
Storms were removed in Patch 1.0, with plans to reintroduce storms in new ways to certain planets in the future.
Cavern Lure[edit | edit source]
Cavern Lures were carnivorous plants that hung from cave ceilings and would ensnare and kill an astroneer if they managed to catch one with their dangling lures. They could be dispatched by digging around their bulb with the Terrain Tool. This would cause them to drop to the floor and explode, sometimes leaving behind 1-3 Research Samples, they also were quite dangerous due to its ability to phase through ground and try to kill the player .
- During one of the streams, Cavern Lure was once referred to as a "Red Dangler".
Cavern Lures were removed in Patch 1.0.
Tumbleweed[edit | edit source]
Tumbleweed was a formation of a giant lethal ball of spikes could be found blowing around in the wind on Arid planets. Getting hit by a single one was not fatal, but getting caught in the middle of a stampede could easily inflict multiple hits. If you are quick, you could get them with the Terrain Tool, and sometimes they would drop Organic which conveys the fact that this object is indeed a flora. The inhibitor mod was a great way to get rid of them. They generally spawned far enough away that you could stay put to avoid them, however they would spawn in sight, which made it look like they were waiting for you.
Tumbleweed were removed in Patch 1.0.
Acid Pots[edit | edit source]
Acid Pots were pumpkin-shaped flora that released green clouds of acidic gas if players moved too close. These clouds would follow the player a short distance before dissipating. When the gas made contact it damaged the player, and could quickly kill them. They typically spawned in groups of three and could be dug up to prevent them from producing gas. They commonly had an organic research item below them, and harvestable organic blobs surrounding them.
Acid Pots were removed in Patch 1.0, replaced by Hissbine.
