Health in Battlefield games is a measure of a soldier's life in hit points (HP). So long as a player has health, they can take action as normal. Damage reduces health, and causes death when health drops below 0. Various sources of healing (usually provided by the Medic class) allow a player to regain health.
A similar game mechanic is used for vehicles, with a gauge representing how much more damage they can receive before being destroyed. This is generally referred to as "armor", though actual armor protection remains the same. A wrench or repair tool can be used to restore a vehicle's health.
A player's (and vehicle's) health usually appears in first-person view HUD (exceptions exist, such as Battlefield 1943 which lacked a health meter), and can also be seen by teammates. Enemy health is typically not visible, but various gadgets in Battlefield 2142 allow players to see an enemy's health.
In most cases, players have a maximum health of 100 health points. In Hardcore, players have a maximum health of 60. In Battlefield Heroes, the various classes have different amounts of health. In Battlefield Play4Free, the Toughness training option can increase the player's health from 100 to 110.
When the player's health is not 0, the player is considered alive and can perform actions as normal. When a player's health reaches 0, the player is considered dead.
In earlier games, to remind the player of their current health, a heartbeat sound typically plays when the player has less than 10% health. In addition, the screen loses some color and goes into black and white. After the player heals from 2% or higher they will regain their proper vision and the heartbeat goes back to normal rhythm.
In later games, visual health indication are still present, though often present themselves in different ways.
As Battlefield 1943 lacked a health meter, the player's health is indicated entirely through appearance of redness around the edge of player's screen. The player is dead when it reaches the middle.
In Battlefield 3, taking a hit will cause a splatter of blood to appear on the edge of the player's screen. If a player is injured, their view will be blurred.
In Battlefield 4, taking a hit will cause splatters of blood to appear on all edges of the player's screen, and cause slight color changes. If a player is injured, their view will be reddened.
In Battlefield 1, taking a hit will cause a curved red sign to appear near the player's crosshair, directing towards the source of damage. If a player is injured, their view will be reddened.
If players are injured, they must find a source of healing to regain health, or in later games, wait until they Regenerate their health. Players typically rely on Medkits provided by teammates to regain health. Other items that regenerate health for the player only include Auto Injector, Bandages, Adrenaline Shots, etc., depending on the game.
- Main article: Regeneration
Battlefield 1943 is the first Battlefield game to introduce regenerative health, which is done by staying away from enemy fire until the player is in full health again. The same mechanic is also found in Bad Company 2, Battlefield 3, Battlefield 4, Battlefield Hardline, and Battlefield 1. Regeneration is made less effective in Battlefield V, restoring only partial health due to enemy harm, and forcing the player to seek a Medic or Supply Station to completely recover.
Healing items also exist in these games, able to start the regeneration process much sooner and make it progress much faster. Auto regeneration is generally the slowest healing method out of all options.
Battlefield V reduces the amount of health regenerated due to enemy harm. Players can still regenerate completely from nonlethal fall or environmental damage.
When the player loses all health, they are put into the wounded state for about fifteen seconds, after which they are considered killed and must respawn. Starting with Battlefield 2, a Medic may use a gadget to revive wounded players. Players in Battlefield V can drag and revive wounded squadmates regardless of class, although non-Syringe revives take longer to complete and does not restore full health.
In Refractor-era games, wounded players may change Customization, and choose an alternate spawn point. Beginning with Battlefield: Bad Company 2, wounded players may see a Killcam. In Battlefield 1, wounded players may choose to wait for or skip a revive, and must wait until they return to the spawn screen to customize.
In Battlefield V, the wounded will bleed out, but can choose to call a medic by pressing Medics and non-medic Squadmates can bring players back from a downed state, the former using the permanently-equipped Syringe and the latter using the more lengthy process of Buddy Revive., and can briefly prolong their revival window by holding . Should a squad in Battlefield V be wiped, any wounded squadmates will expire, preventing other Medic teammates from reviving them. In a departure for previous games, both
Also in Battlefield V, Incendiary Grenades can be thrown onto downed enemies to greatly reduce their bleed out time - when burning, text on the screen will indicate a downed player is "burning out".
For vehicles, the health system works largely the same as infantry. If a vehicle has health, it is able to move and attack and use its equipment. Once a vehicle lost all of its health, it will explode, killing all of its occupants instantly and harming bystanders with the explosion. The destroyed vehicle's hull—or parts of it—can hurt or crush infantry, and obstruct the movement of other vehicles.
In Battlefield 1943, vehicles are still repaired through the use of a wrench, though fighter aircraft like the F4U Corsair and A6M Zero can have their health replenished by flying over an aircraft carrier or runway that belongs to the pilot's team.
Like with regeneration, vehicles in later games also tends to have self-repair functions, though at a slower rate than with a Repair Tool or an equivalent gadget.
- In Battlefield 3, due to rounding, it is possible to survive with 0 health, but any further damage will kill the player.
