This guide aims to provide a complete listing of all the hidden souls rooms and how to unlock them, the rooms are coded with a letter and a number (e.g. B5), the letter corresponds to the Y-axis increasing from top to bottom, the number corresponds to the X-axis increasing from left to right.

This guide assumes Classic Medium. If the method explained here does not work and you're on a different difficulty or mode please report it as a bug on the proper forum! Understand that some adjustment might be needed for other difficulties though.

Guide refers to Ghost as the character, Ghost Mode is the name used for robot possession mode.

Information on Geeks and Secret Achievements is also provided after the Hidden Souls section.

An offline interactive version of the guide can be found here: https://drive.google.com/file/d/1Uq2HDNew5z3FJBpSTp5jTjtv2ZYJCBqh/view?usp=sharing

Trolled... again!


I believe you have a chance to get trolled on any alarm after opening all the valves in the Labs section and up until you complete the Travel Agency portion.

Clearing the path


Cross the whole external corridor using the big biped.

To Know the character


Use the voice routine 3 times. This is the receptionist in the Travel Agency portion.

Looking for permission to make an interactive map? This is the paragraph that gives you the permission to do just that. You're free to use the screenshots and/or info on the guide as long as it is for an interactive map version, since that would be an upgrade of the current form. I don't know web programming and I highly dislike it so have at it.

I don't think I need to give any kind of permissions for Steam guides but if you're a decent person and feel bad using content not made by you this is for you.

Re-hosting is not allowed although I have no way of enforcing it so it's up to your ethics. Linking the guide is of course encouraged as an alternative.


Thanks to the developer, franfistro, for implementing a way to disable top UI, it helped a lot of the images look cleaner and less cluttered.

Thanks to the general community for discussing soul unlocking methods on the forums, I managed a lot of the souls on my own but the last ones were a community effort.
