Riddle of Open Chambers

Good luck with this one. This one was especially hard to make. Hopefully it's worth it! Who/What am I? As they bound back and forth inside rooms with three walls and three floors, I am there also, among their ranks. There are three places from which they view my target, but only one whence I strike. I deal my dealings as one glides across a "U" shaped conductor. I am a high pitch and a low pitch. Pinch me, and I will respond with the tearing of reality.

The Shredder is used by both of these ranks. "Three places...one whence I strike" -Three eyes of the Hive wielders view their target, but only through the gun do they shoot. "U shaped conductor" -The gun itself is a U-shape with a handle. "High pitch and low pitch" -A high note from the sound of the bullets, but a low rate of fire. A high pitch sound, a low rate of pitching the bullets. "Pinch me...tear reality" -If you squeeze the trigger, it shoots void damage. Tear is similar to shred.[/spoiler] My Riddle Archive: https://www.bungie.net/en/Forum/Post/131675380/0/0
