I'm saying that at the begginning of a match, the player gets a vehicle that deploys into a Core with the enhanced self heal abilities.
At the radar stage, they get a vehicle like the original, except that it deploys into a Terminal, which also acts as a construction yard.
If the original Core is lost, the Terminals can rebuild it at the tech center level, but only one Core can exist at a time.
EDIT: Hmm...OmegaBolt does have a bit of a point. The Core is probably the central location for the NEXUS AI and what we see are just empowered nodes.
Core sounds cooler though.
EDIT2: Actually, NEXUS is not a fool. The Cores we see are probably completely self-contained systems that can function even if the Master Core is destroyed.
