The Tempest is a specialist weapon in Call of Duty: Black Ops III, Call of Duty: Black Ops 4 and Call of Duty: Mobile. It fires bolts of electricity which can arc between players, similarly to the Wunderwaffe DG-2, allowing multiple kills per shot.
Call of Duty: Black Ops III
- "This charge-shot rifle discharges arcs of electricity that shock targets and disrupts their nervous systems before chaining to nearby enemies."
- — In-game description.
When an enemy is hit by the Tempest, they are considered dead with electricity running through their body. After a short while, it arcs to any nearby enemies, killing them as well. There is no limit to the amount of enemies it can chain to. The chain will stop once there are no nearby enemies it can link to, or it has already linked once. If the player sees a teammate being shocked, they should take distance to prevent dying from the chain effect.
The Tempest has a slight firing delay as the weapon must be charged before it fires. This means that the player must keep aim on an enemy or risk missing. The reticle is part of the HUD but is still visible when aiming down the sights, which is normally an empty box. However, in Hardcore modes, the reticle is missing, making aimed shots much more difficult to land. The Tempest makes a distinctive firing noise, almost reminiscent to a lightning strike.
Call of Duty: Black Ops 4
In Black Ops 4, the Tempest has been slightly changed. Along with a new look, the Tempest now incapacitates enemies instead of instantly killing them. Downed enemies are forced into third person and cannot perform any action except move. Enemies will take constant damage while downed, to a max of 100 damage from a single shock.
The Tempest chains similarly to Black Ops 3. When an enemy is shocked, after roughly half a second, the lighning will chain to all enemies nearby. Those enemies will also chain after the short delay, until no chains are left. Lightning will not chain back to downed enemies unless another shot is fired.
The Tempest will always kill an enemy who is already downed if they are hit with another shot or a new chain, regardless of their health. Like other specialist weapons, the Tempest awards +25 extra score for each kill, with a bonus +25 score for each enemy chained in a single shot.
Unlike in Black Ops 3, the Tempest fires immediately when the trigger is pulled, and has a short delay between shots as the bolt is pulled. Unlike other bolt-action firearms, the Tempests bolt is automatic and pulls itself, so the Tempest fires much faster than other bolt-action guns.
Two perks can counter the incapacitation of the Tempest. Tactical Mask severly reduces the shock time, allowing the player to stand up much faster, while preventing the Tempest from dealing its full damage. However, the Prophet recieves a notification when a target has Tactical Mask, so they may prioritise you before you can get up. Skulker also greatly increases move speed while downed, possibly allowing escape.
Call of Duty: Mobile
- "Hold the fire button to build up power and send a bolt of lightning at the target. Hits up to nine nearby enemies."
- — Description
The Tempest returns in Call of Duty: Mobile as an Operator Skill.
The Tempest can blast bolts of electricity at the enemies, killing them on a direct hit and immobilize them if hit nearby. The weapon can only fire after a short power build-up. If the player release the fire button in the middle of a build-up, the weapon will not fire.
In Battle Royale, the Tempest sports a unique splash damage effect, making a missed shot less likely to be wasted, unlike in default multiplayer. It can one-shot enemies without armor on a direct hit, but it will take 3-4 shots to kill well-armored enemies, if the player can score direct hits. The shot will immobilize enemies if hit nearby. From Season 10, it fires Ballistic Expert ammunition, allowing it to be reloaded once the mag is empty. The Tempest can only be found in Airdrops as a Legendary weapon.
- While weapons cannot deal damage during the post-round screen, the Tempest can still shock and down enemies, and the lightning will still chain.
- According to the artist who designed the weapon, it is intended to operate on a fictional "super delayed gas system", which was conceived as having a long and regulated gas system which pushes the bolt back a second after each shot, making it a kind of automatic bolt-action rifle.
