Where to find Black Lotus?
If you are searching for Black Lotus than you need to head over to the Gorilla area in Map: N5 / N6 called the Black Garden. It’s a hidden room off one of the ruins. It’s also filled with poisonous gas so you will need a breathing mask.
It’s a bit dark so you have to really search for all the flowers in the room. Gorillas will pop out and attack you.
