Bolts pin killed enemies to walls or floors.
Bolto can puncture a container and has a 100% chance to destroy the container behind it. The Akbolto does not have this capability.
Bolto creates no noise when fired, making it SILENT, but in its upgrade section of the Arsenal its noise level is listed as ALARMING. This is because enemies may still be alerted if the player hits the ground around the target. Boltor, however, does not have the same effect despite it being the rifle counterpart to Bolto.
