These guys self destruct after death by player but if your tame or wild dinos kill it you can harvest its Tech Dino resources. Scrap is better than metal, scrap is 1 to 1 bar where as metal is 2 ore for 1 bar.
Defense Unit

Player-written tips for taming, using, and fighting the Defense Unit in ARK: Survival Ascended & Evolved.
Why is everyone so worried about these droids if fighting the overseer then you should have full gel gear which means you can fly above them and fight the boss in stead of the minions
Do not underestimate this things!!!!
Guys you cannot take this even with force tame
I'm pretty sure that on extinction you can stand on top of them and be semi safe because when I played they didn't attack me
If you just spawned on extinction with no tames and see one, stay nearby for a bit. No threats cus it will kill them for u. Can’t tame anything near them tho or be near with a tame, they will just kill it. But when you just spawned they can keep u safe
They are bosses their bosses on island not on extinction they come in the tek cave so people can stop saying that
Do not drop element whether you use a pick axe or hachet, they drop the same items as tek creatures on extinction, on genesis they explode and you get nothing.
I tried forcetame on ASA and It didn't work. It just showed the Taming Bar (I'm using the Awesome Spyglass mod) and It still tries to attack me.

On Extincion they spawn regually and you can kill them for Metall scrab ,oil and Element Dust , which you can use to make unsatble Element which turns into Element uppon its spoild Timer
Easy way to kill them....use the trike
Whatever you do do not spawn a tamed one and ride it then get off you will fall through map or get stuck and have to leave and come back to fix.
Killed the max level tek stego I was taming in extinction make sure to protect tames when these are around
Ok so If you want to protect your base from the corrupted creatures if you live on the side of the extinction map trap them in a cage all near your base boom.
Stay behind it in order to fight it, it has difficulties turning around quickly, you can be a beginner fighting it as long as you have some sort of tool to help you kill it. :D
U can encounter them by shooting from distance make sure to keep distince
You should be able to hack these, like you will be able to do in genesis 2 to the stridrs. Does Any1 else agree?
I am wrong! I can't even forcetame these things! This is fully untameable!
They now spawn on the extinction map regularly and attack anything but the player which includes tames.
These guys are easy to kill and on 50x give if quite a lot of element dust
Up this so people can get these guys extinct
