How to get Extinction achievement with a mod

Overview

You only NEED one mod to do it, other mods are shown though.

THE MOD

Get Syringes++ By Talonphobia

STEP 1: PREPARATION

Get into a map and spawn a human.
DISABLE LIMB CRUSHING OR ELSE THE HEAD WILL EXPLODE

OPTIONAL STEP 2: GAME END THE HUMAN

You can kill them however you want, just make sure they keep their head, the rest can go.

STEP 3: SYRINGE TIME

Type ‘Immortality’ in the search bar
NEXT

INJECT THE SUBJECT
[OPTIONAL]: Use life syringe to make them not look dead

You’ll know it worked if you see 10000% blood in the inspect menu

STEP 4: DECAPITATION

Cut off their head, make sure you keep the head.

STEP 5: BUILD A DEATHTRAP

I believe the most effective deathtrap is:
A Laser
An industrial Generator
I somehow got a different variation of that to work without the laser breaking wires
I think you have to save the contraption when it’s done to stop the wire break

FINAL STEP: DUPLICATE AND IDLE

Maximize your efficiency, the easiest way to tell this is with a kill count mod, keep duplicating them until the death indicator is constant and doesn’t show deaths
EXAMPLE:
After all that is done, idle for around 4 hours I believe, come back and you should have it or be close
