There are two things that happened when I was searching for soggy cave, firstly I got it FIRST TRY NO JOKE, and secondly I was playing with my brother and when he activated the mob sequence, I activated the lever and we could just walk straight towards the scroll
Tip for harder modes: if you run into the fence,you can hit the switch easily without having to kill the enemies(it might take a small amount of movement tho,but it is easy to do)
There's supposed to be a secret at the very end of that map as well as creepy crypt, where the mouth of the creeper head statue (near the end gate) opens up with a secret button....I can't find/don't remember how to do so
I've seen this happen before. Games being announced way too early and as a result we hear nothing for years because the devs have nothing finished to show us. I'm lookin' at YOU, Metroid Prime 4.
