The map is no longer playable in FE2CM

Poisonous Valley is a community-made Easy Map created by GustForce. It has a total of 6 Buttons (5 standard & 1 group) and is currently playable in Flood Escape 2.


From the name, Poisonous Valley takes place in an endangered valley in the vicinity of poison. There are some tunnels and rocks protruding from the sea floor. There is an overall brownish theme with the modeling, and the model work is intricately shaped but in-textured aside from the acid wall that starts in the corner and makes its way through.


  • When the map was first added, it shared the same OST with Mysterium. This was changed at the June 2018 update.
  • This map is the first Easy map to be added

long after Flood Escape 2 was released.

  • Many players consider that this map should be a Normal Map due to the fact that falling will doom a player.
  • This map is the second to have its own unique acid type. The first was Dark Sci-Forest, being purple.
  • There is a cauldron near the end of the map with the meme "You know I had to do it to em". The liquid in the cauldron also acts as acid. This is the third appearance ingame, proceeding Sinking Ship. If you go inside the cauldron, you can drown.
  • This map has an acid wall where according to GustForce, it is supposed to be toxic gas. It's to ensure no escapee would survive by the end of the map. This is the 2nd to do so, after Graveyard Cliffside.
    • In mid-2021, the acid wall went missing because its code broke. On October 23, 2021, the acid wall is back but is now transparent.
  • The wooden house at the end shows a striking resemblance to the wooden house at the end of Gloomy Manor.
  • NBC (No Buttons Challenge) is possible on this map. Right after you teleport to the map, quickly press the "Low Detail Mode" button then everything in EventScript will stop, except water and change state of it. This concludes that things that are controlled by buttons will stop too. This is due to a precise glitch at the exact right moment would make everything go 5-6 studs up. However, this is no longer possible since the End Zone only opens when all buttons are pressed.
  • Before the poison rises, you can notice the crates already acting like floating objects regardless if poison surrounds it.
  • There are two secret rooms in this map, both are located behind the poison falls near the second button. Squeezing through the right side of the secret room, you can see the FE1 Guide pouring acid on the waterfall, explaining the water's transformation to acid. You can also see a book with an image of Flood Sword on the cover of it and the very point of the Flood Sword. This concludes that the Flood Sword is broken. This was first discovered by NumerousLjbustria (Jasperical) and made public by Gentleberry16 Gerek.
  • If you Shift-Lock into the wall at the third button, you can see remnants of the Map Making Kit.
  • If High Detail is on, there's a small chance you can spawn at the 1st button's platform.
  • The ID of this map had changed due to Poisonous Valley changing into a new map made by GustForce with another wall just like the one on this map and Graveyard Cliffside.
  • This map was rare, as players rarely see this map, until the Map Voting System was added.
    • However, the map is still rare, since it usually appears locked when players vote and only a few times it can be voted without using coins.
  • Poisonous Valley is the fourth Easy map added to Flood Escape 2.
  • A picture of this map can be seen in the secret room of Sunken Citadel.
  • Poisonous Chasm is similar to this map because of the theme. Both maps uses "poison" as their liquid however instead of acid, the poison is lava.
  • If a rescue mission is activated on this map, the escapee will be located on a box floating on the acid river near the second button.
  • During a Lost Page event, the Lost Page would appear at the left of what looks like a laboratory on the other side of the valley.
