"Projectiles reflect off of walls."
The Reflector is a weapon in Axiom Verge that fires a long-ranged, yellow-orange, spinning, S-shaped energy discharge in a straight line in the direction it is aimed. These energy dischages will bounce off walls tangentially if they have not yet reached the end of their path. The number of bounces is not limited.
The behavior of this weapon makes it ideal for use in tight corridors. Trace can fire the weapon from behind cover and bank it off a wall to hit his intended target from relative safety.
The Reflector can be found in the upper portion of Kur, through a drone accessible fissure in the mountainside. This fissure is on the bottom-right part of the 3rd upper large open room with heavy snowfall.
