Whre do you find a Heyenas Key? Share on Facebook Tweet on Twitter 29 viewsJuly 31, 2019Video GamesItems / Equipment 0 GuacamoleFantastic591 March 15, 2019 I have come across a couple of lootable boxes that I am unable to open. It says that I need 0/1 Heyenas key to unlock it. I have yet to find a single key so far. How/where do i get these keys?

They are fairly hard to see since they are not highlighted that well but they are common enough. Once you start looking, you will end up finding a few of them fairly quickly.
