So I don't know if this works on PS4 or PC because I'm a mobile gamer in ark, but if you make the giga trap with three metal gates around a big trap and you lure it, it will get trapped and then you will just need to place the fourth metal gates on the back of the giga, also when setting up the trap DO NOT MAKE IT COMPLETE if you use the snapping points the giga will not fit. Ones you trap the giga you need to clear all danger around so it doesn't eat anything, then place a bed and sleep, or you can go back to base to get your supplies, i would recommend some good like ascendant crossbow or ascendant longneck rifle, but you can also use ascendant compound bow. Also take your time, mean while the giga is there you can go grind the materials to get the giga. When you're finished go sleep close to the giga and when you wake make sure there was nothing around the giga or else you would need to sleep again, ones you wake up, you start firing tranqs, take alot for emergency, ones it's down, put meat in it, the food should me very low meaning that it's hungry basically meaning it should practically insta tame. Also in mobile if you go close to a giga with a creature it will not attack you meaning you can just put the metal gates around it, but remember that's only on mobile. Once you tamed it you've got yourself a tamed giga, please up it took me quite a while to write this.
