The giga is a pretty hard tame if your wanting one. Gigas can destroy lots of stuff, and it has a okay speed. Get a ton of darts and aim for the head, you might also want to stand on a mountain. Bring a lot of narcotics with you, your gonna need it. Add a soothing thing with it as well you can tame with raw meat (normal) if you want but it takes longer. Stock up on food. Also try to keep it safe because for me these guys spawn mainly near mountains and there’s a bunch of threats there. Try your best to keep it safe and safe taming!
