Operative
To infiltrate behind enemy lines in Brink, an Operative will have to use the Disguise Kit which allows him to change his appearance. While this may look like an easy task, players should know that first, they have to find an incapacitated enemy and interact with him. During this process if an opponent spots the Operative, the entire procedure ends.
Additionally, the disguise is removed if the Operative uses his weapon, interacts with an objective, or if he is hit by an enemy Homing Beacon'. In other words, the Disguise Kit should be used to trick the enemies not to gain an advantage during the fight. Another piece of equipment available to this class is the Portable Hacking Device which may be used only near hacking terminals. This process also takes time and can be reversed by Engineers. The closer an Operative gets to the hacking terminal; the faster the process will go; however the procedure may be interrupted for a short time and resumed later.
