If you trap it with a large bear trap, it will stay trapped for about 10 seconds. Use those 10 seconds to tranq it with freinds. When it is tranqed, feed it meat, but when it's torpor drain gets low (which it will), don't shoot it or punch it or anything. Put narcrotics in its inventory and use right tab on Xbox one (there will be a button on mobile), and its unconscious bar will start gaining for a while, and it's health will go up a little, so when you tame it it still has high health, if not damage (it loses damage% when it is tamed)
I dare you to raise one!! They are savage if you got two high lvl parents (about lvl 140ish) and you get imprinting on it. The thing will become an adult with about 230% melee and basically one chomp any bronto!!! But on the down side you loose your job and your girlfriend
When I finally knocked one out, it’s torpor started dropping down hella fast so I had to keep feeding it a lot narcotics and bio toxins and I ran out. So I started running as fast as I can. Always bring a lot of bio toxins, narcotics and other that can keep it knocked out.
Make 4 metal dino gates and 1 large bear trap. Place three frames and door into an incomplete square and the large bear trap in the I between them. Lure the Giga into the trap and while its trapped place 4th down to make the square. Then just light it up with tranqs
