I'd say one of the easiest ways to tame is by creating a box shape with metal dinosaur gateways and put a large bear trap in the middle and a stone behemoth gate in the back, then you are easily able to trap it, close the gate, and tranq easily alone or with friends.
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
5)Your KO weapon (most recommended are ascendant longneck rifle or ascendant crossbow).
6)Your KO ammo (bring a decent amount).
7)Taming food of your choice (most recommended is raw prime meat or kibble if you can).
8)Decent amount of narcotics or bio toxin.
FIND GIGA: gigas usually spawn at mountains. On the island try looking around the volcano or the two mountains in the snow area.
SET YOUR TRAP: take 3 of your metal gateways and make this shape \_/ then put a large bear trap or 2 in the middle. It’s easier if you build the trap on flat ground.
TRAP THE GIGA: get the giga to follow you and make it go inside the trap, then make sure it’s caught in the bear trap. When it’s stuck in the bear trap go behind it and complete the trap with another gateway. The final shape of the trap looks like a Trapezoidal.
KO THE GIGA: even a low level giga has a lot of torpor and it drops fast so keep shooting no matter what. It’s recommended for a tribe-mate to help you.
START FEEDING: put the food in the giga’s inventory and keep an eye on it’s torpor.
I was looking to metal to make a saddle then I said to my brother “i am going to tame a giga” as a joke. Not even 10 seconds later a level 55 giga came into view. KEEP IN MIND WE ARE ONLY LEVEL 40!! We are gonna tame it tomorrow with arrows since we don’t have tranq darts😂 wish us luck!
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
