I am doing a quest for the Bounty Hunters Guild, in which I need to go to a cave called Crimson Hollow in the Upper Plains part of the map. I have finished the quest, but inside the cave I found a massive metal gate (with a safe and a Tier 4 Weapon chest behind it) that I have no idea how to open, as well as one of those glass cases for which I probably I need a key, but I have not found. Anyone know how to open these two? Thanks....

At the start of Into the Mountain quest Master Wizard Albus gives quest but does not give the KEY. Currently level 20, have completed everything else but cannot progress.

I picked it up a few years ago. I was about to start playing, but the rating has dropped and people are saying the devs gave up on it and the maps aren't complete

as the title stated what is the engine used for this game?
