One of the first challenges you unlock after level 20 in Battlefield 6 asks you to get kills while using the Adrenaline Injector on the Assault Class. For whatever reason, doing so is way clunkier than it needs to be, but there are some things you can do to make the process easier.

### How to Get Kills While Using the Adrenaline Injector in Battlefield 6

To complete the class challenge, you need to get a kill within four seconds of using the Adrenaline Injector. During this time, there will be a significant distortion effect around the edge of your screen, indicating the active effect and kill window.

If you want to maximize the number of Adrenaline kills you get, it’s best to use the Injector just as you’re about to enter an objective. I got most of my kills near or at the central flags in Conquest, but you can potentially score two or three kills per Injector if you activate it around a Breakthrough sector.

Thankfully, there’s an accolade associated with Adrenaline kills. If you see the **Berserker** descriptor pop up after getting a kill while Adrenaline is active, you can be sure it counted towards the challenge. However, if the distortion effect on the screen edge is gone, even slightly, you probably won’t get the Berserker tag.

### Tips to Make the Challenge Easier

– **Stick with your squad or stay close to a Support player.**
The Adrenaline Injector has a very long cooldown, but you can halve this cooldown by staying near a Supply Crate.

– **Respawn or redeploy if needed.**
You can also die and respawn, or hit the Redeploy button in the pause menu to get a better position, but there’s no guarantee you’ll be near enemies when you reenter the fight.

In my testing, I could get one or maybe two Berserker kills per Adrenaline Injector use, especially on smaller maps like Iberian Offensive or Empire State. On larger maps like Operation Firestorm, one kill per use is more typical. Overall, I was managing about 10 kills per match, give or take a couple.

Better players are likely to have better luck, but with these tips, you should find the challenge more manageable. Good luck on the battlefield!
