If you want to go toe-to-toe with some of Halo Infinite’s tough bosses then you’re going to want all the Spartan Core upgrades scattered throughout the Zeta Halo Ring.
We’ll show you the location of where you can find each Spartan Core upgrade, how many there are, and how many you need to max out each equipment upgrades.
You might want to find a Banshee for this one or unlock the WASP because finding these Spartan Core upgrades is going to take you all across the Zeta Halo Ring in Halo Infinite.
Halo Infinite All Spartan Core Upgrade Locations
Zeta Halo Ring is divided into quite a few islands. You’ll start in the Northwest of the map and move counter-clockwise as you proceed throughout the campaign.
A little after you’ve completed the main story mission, Pelican Down, you can find Banshees roaming around the open map. You can steal one which should allow you to go to most locations in the map and look for the Spartan Core upgrades.
Below are the Spartan Core upgrades, in order, where you can find them conveniently:

There are 17 Spartan Cores in this region. This is the region with the most Spartan Core upgrades.

How many Spartan Cores are there in Halo Infinite?
There are a total of 45 Spartan Cores that can be found on the Halo Infinite main campaign. They’re scattered across the Zeta Halo Ring and not the story missions so none of them are missable, unlike the Skull locations which may take place in a story mission you can’t visit back.
Why Are There Extra Spartan Cores in Halo Infinite?
There aren’t any extra Spartan Cores in Halo Infinite. If you want to fully upgrade Master Chief’s equipment you’re going to need all 45 Spartan Cores to max out their potential.
Each equipment will take 9 Spartan Cores to fully upgrade. There are 5 upgradable equipment throughout the campaign. You’re free to prioritize which of Master Chief’s equipment you want to upgrade first.
