Battlefield 6: How to Get Adrenaline Injector Kills Here’s how to complete the tricky Adrenaline Injector challenge and unlock the Deploy Beacon gadget fast

If you’ve been grinding through Battlefield 6’s weapon, gadget, and class challenges, you’ve likely run into one that’s caused some confusion — getting kills with the Adrenaline Injector.

While many of Battlefield 6’s progression goals are straightforward, this one requires specific timing and smart play to complete. Here’s everything you need to know to finish the Adrenaline Injector challenge efficiently and unlock the next stage of your Assault Class assignments.

⚙️ What the Adrenaline Injector Does

The Adrenaline Injector is the signature gadget for the Assault Class, available right from the start of the game. Activating it temporarily grants several powerful combat buffs, including:

⚡ Increased sprint speed
🧨 Reduced damage from explosives and fire
💥 Resistance to Flashbangs and Stun Grenades

The effect lasts for roughly 3–4 seconds, after which the injector goes on cooldown — so timing your activation is crucial.

🎯 Understanding the Challenge

There are two challenges linked to the Adrenaline Injector:

1. Weekly Challenge: Get 5 kills while under the effect of the injector. 2. Assault Class Assignment: Get 30 kills using the injector.

Completing the 30-kill challenge unlocks the Q Link 6 (Deploy Beacon) gadget and advances your Assault Class progression. Once unlocked, you’ll also gain access to the next stage of Assault-specific assignments that revolve around beacon use.

💪 How to Get Adrenaline Injector Kills

The challenge’s difficulty lies in the short window you have for kills to count. Only eliminations that happen within 3–4 seconds of using the injector will progress the challenge.

Here are the best strategies to make those seconds count:

🔹 Play Close-Quarters Game Modes

Modes like Team Deathmatch (TDM) or Breakthrough are ideal since fights happen in tight spaces and around objectives. Smaller maps make it easier to push enemies immediately after activating the injector.

🔹 Time Your Pushes

Activate the Adrenaline Injector right before entering combat zones — such as objectives, hallways, or choke points. The goal is to secure kills while the effect is active, so avoid using it too early or while retreating.

🔹 Choose the Right Weapon

Shotguns or fast-firing SMGs work best for this challenge. A weapon like the M87A1 shotgun excels at close range and can help you rack up multiple kills in seconds, especially when storming objectives.

🔹 Pick a Map That Suits You

You can use the custom search function to find maps that match your playstyle. For instance, Empire State (Breakthrough) is a great choice for close-quarters engagements where injector timing matters most.

🔹 Use Bot Lobbies to Farm Kills

If you want to finish the challenge faster, use the Experiences tab to host or join a bot lobby. AI enemies count toward your progress and make it easier to land consistent injector kills without player interference.

🏆 Rewards for Completing the Challenge

Finishing both Adrenaline Injector challenges grants you:

The Q Link 6 Deploy Beacon gadget
Access to Stage 2 Assault Class assignments
Progress toward cosmetic unlocks and XP bonuses

These rewards help you advance faster through Battlefield 6’s progression system while adding powerful new tactical tools to your loadout.

⚡ Final Tips

Keep injector kills short and aggressive — activate only when you’re seconds from an encounter.
Avoid long-range fights; your time window will expire before you can land the kill.
Combine with teammates running Support or Recon to keep pressure on objectives while you push.

With the right map, weapon, and timing, you can complete the Adrenaline Injector challenge in just a few matches and unlock one of the most useful gadgets in Battlefield 6.
