  • Quick Answer: The Ion Core is a brand-new scorestreak, and players can unlock it in Season 3 through the weekly challenges.

The Ion Core is a brand-new scorestreak that players can use in either a Multiplayer match or craft in a Zombies game, arriving with Season 3 of Black Ops 7 and Warzone. This is a mini reactor core that, when activated, damages enemies in a large area around it.

This may sound familiar to those long-time players, but if you haven't clocked it, this basically works just like the Reactor Core from the Firebreak operator in Black Ops 4. We have prepared a simple guide on how to unlock it so you can try it for yourself.

How to Unlock the Ion Core Scorestreak in Black Ops 7 and Warzone

To unlock the Ion Core scorestreak in Black Ops 7 and Warzone, you will need to complete six Season 3 Week 1 challenges. The area of effect streak is the first weekly challenge reward available in the new season.

Each week, the game releases 24 weekly challenges, six for each major game mode (Co-Op/Endgame, Multiplayer, Zombies, and Warzone). Players only need to complete six challenges to get the reward, and challenges can be mixed and matched.

This also means players who don't own Black Ops 7 can still unlock it through the Warzone challenges, as the game is free-to-play.

Once Season 3 ends, the scorestreak can be unlocked through the Armory. First, you need to select the streak as the next reward, and then it will be a matter of playing any game (Black Ops 7 or Warzone) to gather the required experience points.

The list of Season 3 Week 1 challenges is not available at the moment, but once the season starts, we will add them to this article so you can see which ones are easier to do before you jump into the action.
