At first I thought this was a reference to the Legendary Godzilla movies because when the player asks the NPC to start the quest, he says and I quote “Why build a giant drone? To face some giant mutant fire breathing dinosaur!” Or something of that order and when you go to the island you kind of think that’s what he was talking about, since it’s not the first to hear of nuclear testing on the island it made me think we were going to fight a Titan (monster in the monster verse of legendary Godzilla series) and even spotted what looks like primitive fishing villages, that could have been the people who worshipped him, but after further investigation I realized I was wrong, the only reference was just this
How disappointing 😔
