Shoulder-mounted, the Laser Shot fires a lethal beam that cuts through anything in its way. Using it will take way a little more than half of your energy. It does a moderate amount of damage, taking away about a half an energy bar (almost a full on a critical) and will vaporize pilots instantly. If the titan ordnance button is held down, it will hold from firing, but it will eventually fire.
Laser Shots are one of the many abilities that can be mounted on an Acolyte Pod.
At the launch of Titanfall 2, the Laser Shot consumed 500 Units of energy to fire (out of a total pool of 1000), allowing the player to double-tap the Laser in rapid succession. As of Monarch's Reign, the laser now requires 550 energy to fire; instead of rapidly firing two shots, the player must wait a short period of time for that 50 energy to recharge, before firing again.
