I use 4 metal dino gates to trap. Put 3-4 in place of choice (clear carnivores before in the area), leave a gap for giga to enter, then put 1-2 bear traps in the middle. the last dino gate put once giga is in bear trap. i use thylacaleo to lure giga in the trap. thyla is fast and decent hp, put some points in both. i just took lvl 150 on official pve server down with ca 300 darts and 257% longneck. bring everything 20% more than adviced here just in case. put see sleeping bag. once giga is down surround it with 15 wooden spikes but check giga torpor meanwhile, it starts dropping 400 per second. let it drop half then spam narcotics. you can dosm hundreds, check dododex and put more just calculate that 100 narc will up torpor by 4000 so u need it to be half or something to spam all narc in and then sit down and relax. if u have it surrounded with spikes. i put also thyla on aggressive to keep animals away from me, they will probably not attack wild giga, but you. i also bring wyvern and put it on agressive and in turret mode then it will not fly away. good luck!
