Purifier data cores are Purifier structures, used to house the AI personalities of Purifier constructs. When one facility was taken over by a Tal'darim AI, Aurana requested that two allied commanders save the Purifiers from two data cores in the facility.
Purifier data cores are the bonus objective on the map "Malwarfare." The players can spend 350 minerals and 100 gas to save an AI. The download takes 15 seconds and spawns an enemy attack wave. Either player can choose to spend the resources on the download.
