well i saw nobody else doing this so i guess i could make it for you guys.
press interact to spawn the boss. (theres no charging into the core gimmick)
Stuff that i managed to recreate was:
- all the parts and making them breakable (even the head if you headshot it enough times)
- making similar ai to the actual charger
- the death animation
you are free to take and change these assets to your will.
