for people who first played ark (and noob cheaters) heres where to find it:
After you defeat all three other bosses and get their head trophies, go to the volcano and you'll see a terminal put the heads in and a wall will open up revealing 'the tek cave' the final cave and dont forget to bring a bunch of rexes cause there is a garantied giga at the end of the cave also it's very hot and then at on part it switches to very cold then at the end theres an other terminal press e for pc and y for xbox then youll be teleported to 'the observation deck get through there looking at all the cool stuff there and then youll see an implant that's what youre going to fight

WARNING

this fight is super dangerous bring 20 rexes 2 daodons 10 theris and a yuti to ride on good luck

You know, just fly around with a Tek Railgun and a couple buddies to distract the guards and you beat it pretty easy. Although, lightning wyverns never hurt

Definitely my favourite and most memorable battle, I used a dire wolf pack of about 6, a Rex, two spinos, three theriz, an argent, and I rode on the back of a Yuty. Did this in single player without the help of my Ark buddies 👍🏻 These were all very high level dinos btw

When you over prepare and bring 12 tek rexes

This boss isn't really that hard. You can go in with assault rifles and riot gear and beat the boss with 7-10 players. Bring a ton of bullets and healing brews because the defense units do a good amount of damage. Rockets will take out the overseer super quick. Also bring fur gear because it gets cold in some parts. 3 sets of everything are a must in fighting the boss and units. Thank you.

A speedrunner beat it with 2 rexes

Just come with you best Dino’s and prepare to lose most of them

Walk through of the battle: (Sorry it’s lengthy)
Upon entering the arena the Overseer will begin in its stationary form (this form is portrayed above) and will summon a large group of Units and Drones it will then take on its moving form ( a ball of energy) and release electrocution beams in twenty directions.
After removing a quater of its HP the Overseer transforms into Tek variety’s of the three island guardians (beginning with the Dragon then the Broodmother and finally the Gorilla) they are treated as different from the Overseer with their own Boss health bars, upon defeating them it will return to its ordinary form and will repeat this until it reaches 1/4 of its HP.
After this it will orbit between stationary moving and any of the Guardian variantes until it’s defeated.

Can be fought after ascending in the alpha tech cave. Bring long range weapons and take out the minions first for they will kick you off your mount.

Giant ball that I’ve never beat in boss battle

Dododex missed a few commands. For the emotes, do GFI Emote_Flex(or whatever you want) 1 1 0. Emotes are, Turkey, Flex, Snowball, Happy, Carol, Evil, and Nutcracker. Also! For unlocking every Explorer Note in one map, do GiveAllExplorerNotes. Thanks for reading! 🙌

Bring a gun and hope

How to fight it!
Step 1:tame some dodos
Step2:craft a club
Step3: finally go into your battle with destiny you will 100% win

If you play on an Xbox or play station be sure after you beat it you get all of your stuff on a Dino or you’ll lose it. I know, no one will ever truly understand wild card

Bring your best reaper with maxed out stats on melee and health and you win

Anyone notice that it looks like a player implant in it's stationary form.

Use tek Grenades they will take out a good portion of his health use anything tek and if you’re coming from extinction use meks there op I tried to in creative I beat mom in minutes

If you want to fight it your going to need at least 5-10 people and 4-20 tek T-Rex's. and bring a really good gun.

Bring tek rexes maybe a yutyrannus and a few daeodon, take out minions first with a rexes tek gun then go to hell with overseer. Good Luck!

Really hard it your fighting the alpha so make sure to bring all of your best dinos and full tek gear with a lot of element
