I tamed a 145 Giga that I've had my eye on for a while.
I used the metal gateframe method since I'm all by myself. First run I didn't get the final gate placed right and she got out. (Almost lost my argy!) Second time I was prepared for her to pop out, so she didn't bite me when she did. I decided to relocate my trap to flatter ground hoping that would help, but then I had to keep running her in because she kept coming in crooked and missing the trap.
After several tries, I got her in and was shooting her with tranqs, and the SERVER CRASHED. When I got back on, it had reset back to before I trapped her, so I had to do it all again. Such a mess, but I got her!
I named her Bertha.
