Rooted deeply within Terminus in the Genesis Ship Core in Genesis: Part 2

Rockwell Prime is the final Boss of Genesis: Part 2, and ARK: Survival Evolved as a whole. It is the final form of Edmund Rockwell, the previous being Rockwell, and the Corrupted Master Controller.


Comparative to his first iteration, Rockwell, Rockwell prime is much smaller and fleshier. Listed below are all his features in detail:

  • His chest cavity from his original form has sealed but his lower abdomen remains open, he lacks any guts.
  • the once horrid face has reverted back to a scarily human face, complete with stubbly hair near his chin, but he somehow sports a second jaw on the left side of his face.
  • One iris glows in a luminous purple in color and the other iris doesn't glow and is blue.
  • His once tubular tentacles have been traded in for fleshy, rippling tendrils that are more conjoined to form limbs.
  • He has a second, or detached, spine outside his body that has a set of human arms at the top
  • He has eyes and faces scattered around the arena.
  • He has a lot of large tumors across his left side of the body.
  • He is "sitting" on a fleshy throne which is actually a part of his body.
  • He is attached to the walls from the arena with the help of overgrown "limbs" from both sides of his body.

Basic Information[]


Rockwell Prime can only be found in Terminus mission, started via the Mission Terminal underneath his heart inside Rockwell's Innards.

Color Scheme and Regions[]

X mark.svg

The Rockwell Prime always spawns with the same color scheme and has no color regions.

This means it is currently impossible to make alterations to the Rockwell Prime's colors.




  • Gamma Rockwell Prime requires all missions to be completed on a minimum of GAMMA difficulty & have 6 mutagen
  • Beta Rockwell Prime requires all missions to be completed on a minimum of BETA difficulty & have 12 mutagen
  • Alpha Rockwell Prime requires all missions to be completed on ALPHA difficulty & have 24 mutagen


Rockwell Prime is a tough boss to deal with and you will need to have powerful tames and items to take it down.


Phase 1[]

Eliminate all the Super Tentacles (easily seen by its nearly identical appearance to that of Aberration) whilst watching out for the other nearby tentacle that spawns endlessly. If you have brought other dino, have them constantly attack anything that moves. After eliminating the super tentacle, attempt to attack the first node that becomes vulnerable until he starts to mock at you for your attempt. HLN-A will unlock the middle section of the ship, releasing number of Exo-Mek with Hypercharge attachment based on how many survivors are present at the start of battle. The lasers from Exo-Mek are the only way of beating Rockwell Node, and whilst riding on it confers you invulnerable to any form of attack, it will drain the energy over time or while being attacked by anything and everything, forcing the Exo-Mek to be unusable for a while if its fully drained. It will slowly replenish energy over time if its not ridden regardless whether or not it is fully drained. To prevent your mek from being fully drained, exit your Exo-Mek before its energy level hits zero.

Rinse and repeat for the other node, but watch for random acid pool projectile that forms temporary AoE acidic field, which cause health damage to both you and any mounted dino on it. Moreover, Summoner will begin to appear, firing projectiles that spawns in Corrupted Survivor that needs to be killed quickly. Be mindful for his constant tentacle spikes, as it will deal a lot of damage.

Phase 2[]

Upon eliminating all Rockwell Nodes, the Exo-Mek will become non-functional, and Rockwell Prime truly emerges out. More tentacle will begin to emerge, but Summoner will stop appearing (disappears if they are still around) from the ship. Acidic projectiles are spat on more frequently and in clusters, and getting too close to him while riding on a dino confers a huge electricity discharge after a few seconds, preventing you from mounting on the dino. Use rifles and any ranged weapon to weaken him, whilst watching out for his constant tentacles and AoE acidic field.

Upon reaching 0 Health, Rockwell Prime will drop down, staggered whilst HLN-A activates the energy reserves to power up the Exo-Mek for one last blast. You only have 1.45 minute to deposit whatever items you had into dino or lose it ), whistle dino to passive (so they dont walk off edge when they port back to innards as you end up in a dead mode respawning at a bed ), etc... and then fire the hyperbeam at Rockwell with Exo-Mek (everyone must be firing at him to count) until the battle ends (cutscene), otherwise the fight will end in a failure.

Recommended Tames[]

In the final battle, it is fitting that players should pool a variety of mounts that originated from the many maps of ARK. However, note that the space to bring creatures to the arena is not big enough to fit 20 of any creatures, so managing space is important. Also note that bringing 20 creatures that are just as big as the Rex is near impossible due to the small space.

Tames from the Island

  • Yutyrannus to debuff the corrupted survivors and buff allies, as well as for the courage roar. In the Rockwell prime phase, your mounts charging and your yutyrannus roaring with all the chaos going on can make a great screenshot.
  • Rexes are also a good choice for this boss fight. They do good damage to Rockwell Prime and are very good with crowd control to deal with the tentacles and corrupted survivors. it is recommended for these rexes to have high health for this fight. Due to it being one of the largest possible creatures to bring to the fight and with the small amount of space on the teleporter, it is advised to have 1 or 2 and use the rest of the space for other mounts that are capable
  • Daeodon to help heal you allies from Rockwell's acidic projectiles that can easily drain a creatures' health pool.
  • Spinosaurus or its X-variant is another damage mount that is good for the boss fight. With its high mobility and dps, the spinosaurus is great at tentacle killing at a rapid pace. Its high area of effect bipedal attack can clear multiple tentacles at once. Its only weakness is its average health.
  • Stegosaurus is a deceptively good choice to bring to the fight as its health paired with hardened plate and a high quality saddle can make it a tanky mount if lots of points are put into its health. Despite its clear weakness of being the slowest mount, it can be turned into a strength as the Corrupted Survivors will aggro onto them while your main force deals with the tentacles.
  • Allosaurus can act like a pseudo shadowmane if players don't have shadowmanes as they have the same base damage, benefit from a pack buff, and can move fast.

Tames from Scorched Earth

  • Mantis, despite their low health, have deceptively high damage output when paired with high quality swords, allowing them to kill Corrupted Survivors in several hits. Be sure to pump a lot of health points to make up for its inherently low stat and put the rest into melee to make it into a glass cannon.

Tames from Aberration

  • Reaper Kings are powerful tames for this fight. They have strong damage resistance, their spin attack can clear several tentacles at once and their jump ability allows them to quickly get out of dangerous areas, even when slowed by a tentacle attack. Due to the high amount of element on Genesis 2, cloning multiple reapers also poses no real problem.

Tames from Extinction

  • Velonasaurs are another viable mount to bring to the fight due to their ranged attack that can assist in dealing damage and be a ranged fighter when damaging Rockwell Prime. Players on velonasaurs should be aiming at Corrupted Survivors as their turret mode doesn't damage the many tentacles in the arena. Be sure to pump stamina, health, and melee damage to increase its chance of living.
  • Managarmrs are great mounts at being able to dodge the many attacks as well as killing several Rockwell tentacles when it lands from its jump attack. They can also freeze Corrupted Survivors, giving time for you other mounts to kill them and minimizing damage done to them.

Tames from Genesis: Part 1

  • Magmasaurs are great crowd controllers with their smoke attack, magma ball attack, and their oil shotgun attack. The high health can make it a tank. Be careful not to hit your ally tames with its attacks.

Tames from Genesis: Part 2

  • Shadowmanes are very good tames to bring into this boss battle due to their male pack buff and their natural armor, as well as their fast attack speed gives them an edge during the boss fight.


  • The high amount of Rockwell Tentacles in the boss area can do some serious damage to both you and your tames. When the mech breaks you will be very vulnerable until you get back onto a mount.
  • The arena requires a very strong GPU to run well. You may have to play with a significantly lower frame rate than what you are used to, making aiming harder.
  • This boss mainly focuses on the player rather than your dinos, a lot of the damage for the first half of the fight will be directed to the player, even when riding a dino, easily causing death. Bring medical brews as well as many soups, armor, etc. The Exo-Mek given to you prevents taking damage from the acid in the arena.
  • During the final phase of Rockwell prime, Rockwell prime can do damage to your mounts as high in the tens of thousands.


  • This is the last and final step for the storyline of ARK: Survival Evolved, before it moves into ARK 2.
  • All of Rockwell’s forms never actually move, and have all been ones locked in place:
    • Rockwell was trapped in a pit of Element and used his tentacles to attack you.
    • Corrupted Master Controller was also stationary, with the exception of cutscenes using laser attacks to hit enemies.
    • As Rockwell Prime, he uses his various tentacles to attack you while he, in typical fashion, remains stationary.
  • The way Rockwell prime attaches to the wall in the final phase of the battle is reminiscent of a fan art image published after the release of Aberration.
  • Tentacles are actually structures which can be destroyed in bulk via KillAoe console command. This will destroy the gate of entrance and the Exo Mek container too, but the Exo Mek will spawn normally regardless timing.
  • Corrupted survivors are actually the same as corrupted avatars wearing their costumes as they make the same death sound, have the same behavior, can laugh and gobble and if spawned in via command they will appear like an avatar with strong purple glow. There are also "male" and "female" variants only visible via console command
