Do hidden entrances work?

[Plantman Knows Where Plants Grow]

I was trying to use these to guard my base but it seems like after the AI managed to successfully send one guy through that door and into my base it saved it as route system and from then on every agent who has landed on my base started following that route into my base.

I've even watched them pass doors with higher access which should have tipped their AI interest over the hidden doors.

No, they're a waste of time and gold.

Hahaha. I redesigned my entrance removing these in favor of doors and the agents lost interest. Hidden entrances DO NOT work.

IIRC, invaders prioritize doors that are locked or forbidden, so if you used a Hidden Entrance and then locked it, it essentially cancels out the camouflage. One of the things you can do is to put a couple of outbuildings sort of NEAR your entrance, and set their doors to locked/high security, while leaving the hidden entrance unlocked. Invaders will tend to prefer breaking in to the locked doors, wasting the time they have on your island. (Of course, if they can SEE people going in and out of a hidden entrance, then it's obvious that it's a hidden entrance.)

Or if they are "Hidden Doors" apparently the AI prioritizes searching hidden doors even if there is a normal door that has higher access requirements. I tested this.
