Black Mesa - How To Unlock The Post-Mortem ULTRA RARE Achievement!
0In order to unlock the Post-Mortem Interval achievement, you have to go through a whole looooooong process that starts in Chapter 15, Xen, and ends in Chapter 16, Gonarch's Lair. On top of this process, you ALSO have to find the corpses of 7 Scientists in HEV suits in Chapter 16.
As this would take a TON of time to write out, I am just going to advise to watch the video as I explain in detail what to do as well as some tips that will make this journey easier for you. The one thing I WILL say, though, is SAVE OFTEN! This is a pain, and one mistake can have you retrying this process, which can take hours! I will post timestamps for the locations of the 7 Scientists below as well.
JUST REMEMBER, YOU MUST BRING THE CYANOGEN CANNISTER WITH YOU AND DO THAT WHOLE PROCESS OR THE SIDE PATH THAT LEADS TO WHERE YOU USE IT WILL NOT BE OPEN, PREVENTING YOU FROM GETTING CORPSE 7!
