when you go to the top science base at the volcano, there will be a two story building, on the first story there will be an elevator leading to a pitch black bunker, need a flashlight or nightvision, you'll have to navigate through the vents, i got lucky and my first trip through the vents and found the crystal in a room, if you find a keycard door you'll have to find the keycard{else where}.

i killed the boss, but how do i get the keycard now?

I finished the search with a friend ：）I published the guide on Baidu. lol

One of them is in a maze of volcanoes in the south, and the other is a sea cave in the southeast of the map
