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.

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
  • Completing 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. 

Progress will not carry over to consecutive matches if the squad is disbanded. However, if all members of the squad stay together after the map rotation/faction switching, the lost progress will be refunded back to all members after the first squadspawn in the new match.

Trivia[]

  • The Shadow path was won in a contest by DICE that was meant to add the most popular of four paths created into Battlefield 4.
  • 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.
