The gamemode is only available to owners of Battlefield V and was released on March 25th, 2019.
Firestorm pits 64 players against one another in a large scale deathmatch on the map Halvøy. The map features multiple terrains and environments, and is approximately ten times the size of Hamada. Solo, Duos, and Squads are the three variants currently available.
Unlike in normal multiplayer, players do not spawn with any weapons or gadgets and must scavenge them from around the map. Vehicles, such as tanks and transports, are located sporadically around the map and can be used accordingly. Engagement with enemy players is enforced as the map boundary periodically shrinks from the firestorm. Eventually, the firestorm will completely overtake the entire map unless only one player or squad remains alive.
Before the start of a match, players may choose a multiplayer class from both factions. Classes are cosmetic only and do not have any additional benefits. Afterwards, players are placed in a hangar with a destroyed Ju-52 until enough players have joined the match. While waiting, players can pickup and try out various weapons scattered throughout the hangar. Once the player threshold has been reached, the hangar emergency lights will activate. The hangar doors will then open to signal the start of the match.
Matches start with a group of Ju-52s on predetermined flight path over a random area on the map. Players then have the option to mark a location and airdrop out of the plane to the ground. Should a player fail to leave the aircraft before it leaves the map boundaries, they will subsequently forfeit the match. Upon landing, players must scavenge for weapons, gadgets, armor, ammunition, and vehicles.
As a match progresses, the firestorm will periodically close in a circle around a random area on the map. The edge of the circle is depicted as a wall of fire which will obstruct vision for anyone caught in the storm. It will also inflict damage on any player within the storm until they reach safety. As the storm shrinks, players are forced to engage against one another in order to avoid the storm. Eventually, the storm will overtake the entire map unless one squad or player is left standing.

Firestorm features several objectives that award players with various degrees of loot upon completion.
- Strongbox - Red wooden crates that appear randomly around the map, typically at notable locations. Once opened, they may release Common, Rare, or Epic tier weapons, gadgets, or healing items.
- Safe - Randomly located at notable locations around the map and will not appear on the mini-map and HUD. Safes hold high-value loot and take a considerable amount of time to open. This leaves players vulnerable to attack while cracking them.
- Resupply Points - Capture points scattered around the map at random that reward players will high-value loot. The location of these points is denoted by a large Barrage Balloon in the sky. The map features over twenty resupply points, with three points active at any given time. Once active, all nearby players will be notified of their location. Points are captured more quickly if they are held by more members of a squad. Points may still be captured from within the firestorm. All active resupply points will reset once the firestorm has reached the next safe boundary.
- Vehicle Lockup - Bunkers located across the map. Often house Safes, Strongboxes, Gasoline, as well as heavy and light vehicle ammo. Within are heavy vehicles and Epic tier weapons and gadgets. Vehicle Lockups are opened by turning both mechanisms on either side of the structure entrance. An alarm will sound to notify all players in the vicinity once the mechanism has started moving. The alarm will only stop if players stop turning the mechanism or if the Vehicle Lockup has been successfully opened.
All players start the match with an empty inventory. Players are allowed to carry up to two primary weapons, a sidearm, and four different ammo types. Additionally, players have four gadget slots. Two of which are for healing items and grenades. The other two slots are reserved for any other gadgets that can be found around the map. Gadget slots and the amount of ammunition able to be carried may be increased by finding and equipping Backpacks. Small, Medium, and Large backpacks may be found, increasing gadget slots by two, four, or six respectively.
Armor and Health
All players start rounds with 150 health. Health Regeneration is not available in Firestorm. This requires players to find and use Syrettes in order to recover from damage. Once enough damage has been taken, players will enter a DBNO with 300 health. This state allows players to slowly crawl towards safety, as well as fire an equipped sidearm. Squadmates must perform Buddy Revives in order to bring players out of this state. Should a buddy revive fail, players will be permanently killed and enter Spectator Mode.
Damage to health can be buffed through Armor Vests. Three armor vests rarities are available: Basic, Medium, and Heavy. These vests hold armor plates which add 50 points of health protection a piece. The medium and heavy armor vest rarities increase the number of armor plates able to be equipped by two and three respectively, enabling a maximum of 150 points of health protection. Like all other items, armor vests and plates are scattered around the map, with up to five armor plates are able to be held at any time. Plates are not automatically applied once picked up and must be manually equipped. Upon sustaining enough damage, plates will break and a player's health will be exposed. Broken or damaged Armor vest may be swapped out at any time should a player have additional plates.
Squad Reinforcements are available to all players in the form of the Flare Gun. Unlike multiplayer, they do not require requisition points to unlock and can be found around the map as with all other items. Squad reinforcements are available in four rarities: Common, Rare, Epic, and Legendary. The rarity of the reinforcement denotes the color of the smoke that will be released upon firing the Flare Gun.
A total of 17 weapons are featured in Firestorm. Weapons are available in four rarities: Common, Rare, Epic, and Legendary. The rarity of a weapon denotes the specializations equipped on a weapon, with common weapons featuring no upgrades. Weapons perform in the same manner as in multiplayer. Shotguns and sniper rifles, however, have had their damage values reduced to prevent one-hit kills. Each weapon type requires a specific type of ammunition which, like weapons, must also be scavenged from around the map. The June 24, 2019 update allowed owned weapon skins to display on weapons once picked up. Skins must be applied to weapons before the start of a match in order to display. 
Vehicles are prominently featured in Firestorm, with a total of 17 vehicles available. Transports, Armored Transports, and Emplacements may be found scattered throughout the map. Combat vehicles, however, are only found by either the Vehicle Drop reinforcement or inside Vehicle Lockups. All Vehicles start with a set amount of Fuel and ammunition. This requires players to refuel and resupply them with jerry cans and heavy ammunition scattered around the map in order for them to keep functioning effectively.
- Announced at the EA Play Event on June 9th, 2018, the idea to add a battle royale mode to Battlefield V came from conversations DICE developers were having about the game inside the studio as opposed to being a directive that EA handed down to the studio. Games such as Fortnite and PlayerUnknown's Battlegrounds were popular among DICE staff members.
- Three Dog-Tags were added to Battlefield V months before the release of the gamemode. These dog tags were later replaced with the current dog tags and are unable to be obtained.
- The Duos variant was made temporarily available from April 11 to April 15, 2019. It was added again on April 19, 2019 and was disabled on May 9, 2019.
