Hunt Where You Can Get the Chips You Want!

You can get chips through the event, so check the event in the top right corner. The weapon tab guides you to the hunting grounds where you can obtain chips for each desired weapon. So, if you hunt in those specific areas, you can get special weapon chips~!! Other chips are usually obtained within 1-2 tries, but the trajectory chip for the gun obtainable in hunting ground #4... I've tried over 10 times and still haven't gotten it.. Is this a bug?ㅠㅠ
