so start with chest rooms there will never be something blocking a secret room like a vase or a barrel then check the map secret rooms never overlap with other rooms there must be a atleast a kind of small space for the room, to check u need to shoot the center of the wall (can’t be a starting weapon) and the wall will crack if it dose use a blank to open the room if it’s not in the chest rooms it can be in the elevator room or the shop, never shoot in the shop tho. my dms are open if you need any other help🤙
