Fortnite’s Cold Blooded syndicate has taken over the island, guarding secret vaults packed with high-value loot. To grab the prizes inside, you’ll need to take down the new bosses, grab their Vault Keycards, and find the hidden locations before rival squads move in.
Two of the Most Wanted quests involve the bosses and vault areas. One quest requires you “visit named locations containing Cold Blooded Vaults,” not necessarily requiring you to open them up. Another quest requires you to “collect a Vault Keycard dropped by a defeated Cold Blooded Boss.”
There’s a boss and vault in Shattered Slabs, Brustal Bastion, and Faulty Splits. Luckily, in each of the three areas, the boss drops the keycard and the boss is also pretty much directly outside of the vault, making it easy to figure out. You’ll run into some small-fry NPCs around the boss, but you’ll know you’re fighting the boss: Their health bar will have a blue shield (as boss NPCs usually do).
The best thing to do is to drop in the area, gear up with some weapons and shields, take out the other players, and then head to the vault area. If you go there and see that the boss is gone and the vault is already opened, that means another player must have gotten there first.
Once you take down the boss, you’ll need to pick up the Vault Keycard, which takes up an inventory slot. With the keycard selected, an arrow will point you towards the vault.
Inside the vaults, there’s tons of loot, like gold bars and Boom Sniper Rifles, which should help you complete other “Most Wanted” quests as well.
Best loadout and strategy to defeat Cold Blooded Boss
Cold Blooded bosses in Fortnite Chapter 4 Season 1’s Most Wanted event have high shields and health, requiring a focused loadout and careful positioning.
Recommended Loadout
Equip weapons optimized for shield-breaking and sustained damage:
-
Primary: Ranger Shotgun or Tactical Shotgun (close-range burst after shields drop).
-
Secondary: Combat AR or Rapid Fire SMG (consistent shield DPS).
-
Heavy: Rocket Launcher or Grenade Launcher (quick shield strip and add clear).
-
Full shields (200+), medkits, and mobility items like Shockwave Grenades for escapes.
Strategy Steps
-
Land at the boss POI (e.g., Shattered Slabs) and eliminate patrolling henchmen first to isolate the boss.
-
Break shields rapidly with explosives or AR spam from mid-range, then close in with shotgun for health phase.
-
Dodge boss melee swings and henchman reinforcements by circling; third-party players are common, so rotate positions.
Loot the Vault Keycard post-defeat for nearby vault access.
Cold Blooded Boss location and spawn time
Cold Blooded Bosses in Fortnite’s Chapter 4 Season 1 Most Wanted event spawn consistently at three fixed points of interest on the map.
Boss Locations
These bosses appear every match at the following named POIs, patrolling near the central vault areas:
-
Chaos Double Agent at Shattered Slabs (southwest map edge).
-
Double Agent Hush at Faulty Splits (southeast, often near the bowling alley).
-
Cold Blooded Ace at Brutal Bastion (northeast).
Spawn Details
Bosses spawn at match start alongside their henchmen guards and remain until defeated; they do not respawn in the same game.
Areas are high-traffic zones, so expect player competition-check for blue shield bars to spot them quickly.
