Backdoor

"Gain control of an automated in-world object by exposing a backdoor vulnerability. Version 2 lowers the latency requirements of this subroutine, thus giving it a smaller cooldown time."

- Version 2.0 In-Game Description

Backdoor is a hacker resource featured in Battlefield Hardline. It allows the Hacker to take control of objects placed around the map such as security cameras which spot enemies in the vicinity, electrical boxes which explode when tampered with, and gas containers which release lethal gas when enemies approach them. Upon unlocking version 2.0, the cooldown time for the resource is lowered from normal.

Players who notice enemy controlled objects can destroy them for points. Despite this, however, Hackers can regain control of objects by redeploying the resource.
