The Carbonizer is the Trust's ultimate weapon. When the trigger is held, this weapon fires out a continuous beam which drains the enemy's health at a steady rate. Though this gun is one of the most deadly, it has its drawbacks; they are the long reload time and a large amount of lag after firing, which make this weapon less effective for campaign use, since there's a lot more enemies you have to face in the campaign. This weapon appears twice in the campaign mode, both times it is just found lying around for you to pick up and use. Similarly to the USP45, there isn't a single enemy you face in the campaign that ever uses a Carbonizer.
Online, this weapon is found in the Trust, Close Combat and Chargeable Weapon Sets as a "power weapon".
