— Version 2.0 In-Game Description
Backdoor is a hacker resource featured in Battlefield Hardline and one of the most common resources used within the game. It allows the Hacker to take control of objects placed around the map. Upon unlocking version 2.0, the cooldown time for the resource is lowered from normal.
Objects that can be controlled include:
- Automatically spots enemies in clear view.
- Gas canister
- Floods an area with gas, similar to a Gas Grenade.
- Releases a blinding flash of light, similar to a Flashbang.
- Battle Pickup
- Additional Battle Pickups can be unlocked at certain locations.
The Camera provides its own field of view when selected. Other assets can be observed via non-interactive surveillance cameras. Harmful assets are triggered when an enemy player enters its area of effect. After being triggered, the asset will have a "recharging battery" icon and regenerate.
Players can spot hacker-controlled assets, and temporarily disable them. Damaged assets will have a wrench icon, and automatically repair after a period of time.
