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
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
If you’re trying to kill this bro for the achievement, here’s how I did it. Get yourself a Quetzal with a platform and put about nine auto turrets on it. Put about 100 bullets in each turret and find yourself a Giga. Make sure the turrets are on high range and turn them on as soon as you’re close to the Giga so you waste as little bullets as possible. Just start circling the Giga and stay out of the hit range. Boom, dead Giga in about five minutes.
I was playing on a nice multiplayer survee with nice people, I got a bronto, mutated blue wolf, eerie tapejara, and an argie. I join a tribe with someone and we go to his base (on the back of fars peak and right across from carnivore island) and one day I spawn in, and see one of my arges died, I'm like oh. It must have starved. That's sad. Then I look at the logs and see "your dodo has been killed by a giganotosaurus!" I instantly start panicking and I type in the chat about it. Everyone is curious. Low and behold I see a giant giga tail right next to my flimsy base with spike walls. It agros on me, and I start RUNNING. My bronto attacks it and the behemoths fight. My bronto's death was not in vein though. I had enough time to save 5 out of 17 dinos. I'd say that's pretty good compared to nothing. I still have their graves to this day.
