This achievement is unlocked for finding all 5 ciphers distributed in the Holding Pen C: Specimen Processing, Holding Pen C, and B/C Secondary Generator Shed maps. Once all 5 ciphers have been clicked on this achievement will unlock. This can be done over multiple runs of the operation, or in one. However it must be done during the two add rush phases, making this easiest to obtain in [STORY] difficulty. There are multiple spawn locations for Secrets of Czerka, Vol 01 and Secrets of Czerka, Vol 03, however they always spawn inside their respective sheds and are quite easy to find. Secrets of Czerka, Vol 02 also has multiple spawn locations, however it seems that it has been spawning with greater regularity at -359, -226, this is by far the most difficult of the 5 to locate. Collecting all 5 ciphers in one instance will allow you to unlock the locked down elevator later on, skipping the stairs, and granting a character title. The activities needed to complete this are;
