Power cores, also referred to as fusion coils, are Forerunner devices presumably used to store energy to power up Forerunner machines. They are recognized by their low pulsating humming, and can be found mounted on walls on some Forerunner installations. An explosion of a power core can be lethal at close range. There are similar, although larger devices called energy cores.
Power cores can be seen in Halo 2 and Halo 3, in campaign and multiplayer levels. They can be used to kill anyone who passes by if they are shot at. However, it takes two power core explosions combined to kill somebody with shields. In Halo 3, certain maps can spawn the power core in Forge.
- When two power cores explode in Halo 2, one will throw the other into the air where it explodes much like a fusion core, but in Halo 3 they both explode simultaneously like a plasma battery.
- The power core is one of the least seen explosive objects in the Halo series in campaign.
