To knock it out you get it stuck in between 4 metal Dino gates. How do you do this is have at least u and a friend. What you do is put up 3 gates in a square shape. Fly a bird and have the giga follow you. Make it run to the trap and once it is in the trap use a friend to put up the other gate to stop it from getting out. Don't use a gate just the frame. Than you just tranq it while it is stuck. Easy peezy!!!
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
Breeding is best when u raise atleast 6 to 10 at a time. Reward is greater for same time period and time will pass faster for you while occupied feeding so many. Another trick is to run ur gachas for ele while you raise. Two things at once
