How to unlock the hidden chamber in the Abandoned Aqueduct

The title says it all.

The how

There are hidden buttons placed across the Abandoned Aqueducts.

Only two buttons spawn at one time.

For the buttons, you need to have both of them pushed at once.
Since I was up way too late finding this out, I didn't have any friends to test out if it is possible to have two people puss the buttons, and have it activate.

I managed to push one of the pots with my character onto one of the buttons. For the other button, I pushed it down with my character.
After that, the gate should open.

If you're having trouble moving the pots, or you just get them stuck, try to launch the pots. You should be able to dash into it to make the pots go flying. I used huntress' teleport which shot the pots flying hella far. Keep in mind, for her, you need to be a little distanced away from the pot, or else the game wont realize you dashed at it.

Edits:

• It is possible to push them both down with different characters in a multiplayer run.
  
• Enigneer's turrets push down the buttons if placed upon them, and you will be able to open the door with them.
  
• The Purple Box equipment item is able to pull the pots to move them.

Button Spots

The buttons are spread randomly but in specific spots.


I don't think I have found all the button spots but here are the ones I have found thus far::

Button 1:


Button 2


Button 3:


Button 4:


Button 5:


Button 6: (thanks to Ninjab33z for finding it)


Button 7: (thanks to NeKappa for finding it)


Button 8 (thanks to NeKappa and MrPeters for finding it)

Behind the door (spoilers if u wanna find out yourself)

Behind the door is two Special (not elite) Elder Lemurians. They are mostly minor bosses, and are little hard. And I was playing on drizzle when I fought them.

Edit:

• These two Elder Lemurians always drop their respective band of fire or ice.

If you have any questions, feel free to ask them in the comments, and don't hesitate to tell me I messed up. This guide is for you, not for me.

You can clip through this door on the right going in and the left going out with multiple characters. I've personally done it was MUL-T, and Merc.

I'll test out the huntress glitch more to see if it's possible to repeat. Adding constant ring drop.
