Borderlands Pre-Sequel 360 NO SCOPE – Achievement / Trophy Guide
If you choose Nisha the Lawbringer you will start out with a sniper rifle. Follow the story and collect the “Oz Kit” to get the ability to double jump. This will give you enough time to spin 360 degrees and no scope an enemy in the air.
Press A/X two times to double jump. Make sure you kill all enemies in the area you want to do this except for one. Now you can take your time to get the trickshot right.
