[Spoilers]Settlement Alfa

What’s with the blocked cave at there?Can anyone give any hints,possibly about the plot relating it?

I don’t think you can go in the blocked cave. However, you can find a Delta Croagunk in the nearby jungle.

Pretty sure it’s just for the story.

It does nothing. As an npc says, it’s just filled with croagunks and you get the delta elsewhere so I doubt it can mean anything
