Use a high level drake with lots of stam, (dont waste your time leveling up damage on your drake, it will be used for running) an ascendant shotgun with lots of shells, extra hazmat, and a buttload of Megalosaurus for actually fighting him. (The shotgun and drake are for fighting the tentacles)
have playing ARK since shortly after it’s initial EA release in June of 2015. Ever since the first Explorer Notes were released I’ve been fascinated by the story and background of the game. I’ve watched countless videos, listened to commentaries, read comments, theories, etc… And very few people really seem to have a cohesive image of what’s going on and why, or even a general timeline of events.
Frankly, I doubt that we have been given enough information for any one person to be 100% correct about everything, but I’m going to write down what I believe is a pretty solid account and I will be using Explorer Notes and maybe Dossiers (if applicable) as references, just so I can prove what I’m saying.
So yeah, let’s get started:
The Inciting Incident
We awake in a mysterious land without having any memory of how we got there. The ecosystem seems pretty standard, but our attention is immediately arrested by the three enormous free-floating structures that dot the horizon, Obelisks. Unab
Considering he’s a boss, there’s not much utility to him, other than getting bonus levels from Aberrant Ascensions.
Though if you think about it, Rockwell (before at least) had a ton of utility. He made all of the cooking recipes (as suggested by the Rockwell notes that are somehow everywhere), and it’s heavily implied that he made a good portion of the technology available to you in Aberration.
Still, what a sad and twisted way to go for probably my favourite character in all of ARK: Survival Evolved’s storyline.
Rockwell can be found in the Rockwell arena beyond his designated terminal, I believe it’s beyond the Graves of the lost (or commonly called the Rock drake nests) but it’s somewhere there.
Also to fight Gamma Rockwell like any DLC boss you need the three artifacts.
How to fight Rockwell:
Firstly Rockwell is in the center of the arena, stantinary in a pool of molten element, please do note that whilst his five tentacles are up Rockwell can not take damage, he attacks by jetting out balls of energy that Beal area damage, electrifying the ground with a tentacle slam and summoning Nameless plus Elemental Repear kings.
To defeat him, you must destroy all tentacles before attacking his heart in the center, note that he can raise his tentacles again so you must repeat the proses.
