EASTERN AND WESTERN ANTECHAMBER LEVERS

How to open Antechamber doors on the left and the right side

WESTERN LEVER

To unlock the left door, or the western door, of the antechamber, you need to find a special key to draft the SECRET GARDEN



You also need to draft the WORKSHOP

In the WORKSHOP, you need to combine the following items:
BROKEN LEVER + SLEDGEHAMMER + BATTERY PACK = POWER HAMMER

In the SECRET GARDEN, you will need to solve a puzzle. In the far end of the garden, there is a fountain with a weathervane. The arrows on the weathervane need to point toward the crescent Moon on the wall. You change the direction of the arrows by turning valves around the fountain. One valve is behind a wall. You need the POWER HAMMER to destroy the wall and use the valve.

Once all arrows point to the crescent Moon, the lever for the door will reveal itself. This seems to persist through all runs.

Some have reported that they didn't need to do the convoluted process of getting a power hammer to break the wall. I had no such luck.

EASTERN LEVER

To unlock the right door, or the eastern door, of the antechamber, you need to draft the GREAT HALL:

Behind one of the doors is the lever. The middle door on both the left and the right does not necessarily lead to the next room.

Bottom lever (or *a* bottom lever) is behind a wall at the Weight Room, requires the power hammer to break

I've also found that they mention in the Security emails that there's redundancy for the levers, so it seems likely that there's two of each lever

I found a lever in one of the diagonal rooms of the Mechanarium once

for those of you mentioning either needing, or not needing the power hammer for the secret garden lever it has 2 levers, the west one doesnt require the hammer, the east one does

The secret garden can open east OR west depending on the direction of the arrows.

In my run, The 3rd arrow was in the correct direction already and did not need to set it from the greenhouse either

I didnt need the hammer? Maybe I was just lucky that it was already pointed correct.

i believe it is random where the crank wheels are in the Secret Garden, first time i visited it had both wheels near the weathervane.

i did notice the wall looked very "destroyable" and figured it was another secret i hadn't gotten to yet.

I didn’t need the Power Hammer either the third lever is in the Greenhouse room, but you have to fix the broken lever before hand.
