Hacker Mode is a feature of Battlefield Hardline. Similar to Commander mode, it allows players to support their teams through a variety of actions. Each team's hacker works to gain control over objects in the field, hinder the enemy hacker's efforts, and provide their team with temporary upgrades. Like the commander in Battlefield 4, hackers can earn awards and cash towards progression for their performance. A player already present in a server as a field agent may assume the hacker position, and an active hacker can leave the position and become a field agent, as could be done in Battlefield 2/2142.
The hacker is provided with a top-down camera view of the battlefield, the team's squad list, and a menu of abilities that can be performed on map objects or players.

Control a map asset, neutralizing enemy control if held. Earns a "Jacked In" bonus when asset is controlled, and another bonus when the asset is triggered. Together with Trojan, these abilities limit enemy hacker presence.
