The Data Core, abbreviated as core, is an object found in some Invasion game types in Halo: Reach. It is a device that contains classified information. It is usually the final objective in an Invasion game but does not necessarily have to be the final objective.
The attacking team is required to take the Core from its spawn point and carry it to an extraction point. Depending on who the attacking team is the core can be of UNSC or Covenant design. Both are carried like support weapons but you cannot use either of them as a weapon.
- On the level: ONI: Sword Base, at least one computer screen shows a picture of the data core storage device. It is labelled as "Laser Core," on the screen.
