Field Upgrade

A Field Upgrade Path

Field Upgrades are a game mechanic featured in Battlefield 4. Functioning in a similar manner to the Specializations of Battlefield 3, these grant additional abilities to players.

Field Upgrades function in a similar manner to Battlefield 2142. There are 29 different field upgrades available for use when choosing from the 11 available Upgrade Paths (short for Field Upgrade Path). Each path holds up to four different field upgrades that are obtained by progress chained by squad-based team work.[1] There are a total of eleven upgrade paths, with three paths available for all classes and two paths unique to each class.[2]

Paths can be freely chosen anytime during matches with progress for each path saved whenever a new path is chosen, a kit has been changed, or a new squad has been joined. Some progress, however, is lost for the path currently in use whenever the player and their squad have been wiped. Progress does not carry over to consecutive matches.

Three of these field upgrades are initially locked. As the squad completes objectives, or the squad is granted a promotion by the commander, the remaining field upgrades are unlocked and stack. Some of these objectives are as follows:

  • Killing enemies
  • Repairing vehicles occupied by squad mates
  • Resupplying squad mates
  • Healing squad mates
  • Spawning on squad mates
  • Competing objectives given by the squad leader
  • Saving or avenging squad mates from enemies

If every member of a squad is dead or has yet to deploy, the squad loses the use of one field upgrade each time this occurs. This system replaces the collaborative system in Battlefield 3 and the potential waste if squadmates selected the same specialization. Upstanding upgrades at the end of rounds will be carried over to consecutive matches on that server.

Upgrade Paths

All Kits

Name Image Description Specializations Unlocked
Offensive BF4 Offensive Icon These give you quicker sprint speed, more available ammo magazines, one extra hand grenade, and allows you to fall from greater heights without taking any damage, respectively. This universal upgrade path is great for players who enjoy being at the front lines and leading the charge
  • 28000 (Assault)
  • 33000 (Engineer)
  • 27000 (Support)
  • 22000 (Recon)
Defensive BF4 Defensive Icon These grant you increased protection from shots to the chest, a decreased rate of being suppressed, decreased damage from explosions, and a shorter time span before the out-of-combat health regeneration kicks in. If you are more defensive-minded, perhaps playing as Support from the sidelines, this can be an excellent choice. Default
Shadow BF4 Shadow Icon Inspired by the fabled shadow warriors of the Orient, the “SHADOW” career grants you the mystical powers you need to infiltrate enemy territory without being seen. Okay, not really, but it grants you some perks that accumulated will give you an edge when going behind enemy lines. Default

  • Some of the paths are based on Battlefield 2 classes, namely Anti-Tank, Spec Ops, and Sniper, based on the Anti-Tank, Special Forces, and Sniper classes respectively.
