Rising Acid is a disaster in Survive The Disasters 2.


Rising Acid is a flood-type of disaster. After it starts rising, any destructible block the acid touches has a 33% chance to be corroded and disintegrate; ones that remained become radioactive and glowy, touching a block that glows deals 7 damage a second. If you come in contact with the acid, you'll be dealt a damage of 18 quickly, so it is wise to get to higher spots where the acid can't reach you.

For the hyper counterpart, the acid rises twice as fast. It has a 50% chance to disintegrate blocks, remained ones deal 14 damage. Also deals 24 damage if you fall in it.
For the impossible counterpart, the radioactive parts deal 28 damage. The acid rises up a lot sooner and higher, reaching up to 16.6 studs above the baseplate at a rate of 4 studs per second. Also deals 30 damage if you fall in it.

Disaster Memo Information

"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!"

"Compared to standard Rising Acid, the acid rises 2 times faster and has 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."

Survival Tips

  • Breakable structures may become unstable upon contact with the acid. Be sure to use a Gravity or Fusion Coil to buy yourself some time or jump to higher ground.
    • If you can, try to reach a high point that cannot be affected by the acid.
  • Try not to touch any of the acidic blocks until the map changes or another disaster gets rid of them.
    • You can tell that blocks are acidic if they appear in a neon light green color.


  • Prior to Version 41.5, if you had contact with the rising acid, players could die immediately (similarly to Rising Lava), as there was no time left for players to heal.
  • In older versions, when you touched the acid, your body (parts) could become rusty, even though it didn't affect gameplay.
  • 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.
  • In Survive The Disasters 4 (April Fools 2018), the disaster warning was renamed to “acid”.
