Rising Acid is a disaster in Survive The Disasters 2. It also appears in Survive The Disasters 1 as a simple disaster.


"Any breakable parts that come on contact with the rising acid have a 33% chance to disintegrate. Breakable parts on contact will turn radioactive and touching it deals 7 damage, even after when the disaster is over! If you are in the acid you'll deal 18 damage over time. The acid rises up pretty high and quick, get to a high place!"

Hyper Memo

"Compared to standard Rising Acid, the acid rises 2 times faster and have a 50% chance to disintegrate breakable or body parts. The radioactive parts now deal 14 damage, and the acid will damage you 24 overtime when you are in it."


Rising Acid is a disaster that has lasting effects after the disaster ends (others include Missile Strike, Redcliff Warriors, Korblox Mages, Illumina, etc.), in which any block the acid touches have a 33% chance to disintegrate; ones that remained becomes radioactive and glowy, touching a block that glows deals 7 damage a second. If any part of your body touches the acid, it will deal 14 damage over time. It is recommended to stay on high ground, away from the acid.

  • In older versions, when you touched the acid, your body (parts) could become rusty, even though it didn't affect gameplay.

    Said 'rusty bodies'.

  • In older versions, the memo of Rising Acid was glitched. Even after the player has collected it, it wouldn't appear in your memo inventory. This has been fixed.
  • In Survive The Disasters 4 (April Fools 2018), the disaster warning was renamed to “acid”.
  • In older versions, if you had contact with acid, you could die immediately, as there was no time left for you to heal. Your body corroding counts as damage, and if all of it corrodes, it's an insta-kill.
