In certain rounds during Infection, players will be notified of a civilian requiring rescue. The players have to escort the civilian to a specific location, protecting him from zombies and other threats, so that the rescue Warbird can pick him up. A successful extraction will grant each player a free upgrade for the current weapon they hold. Starting on the third successful extraction, orbital drops will also be rewarded. Failure to extract the civilian will result in a Power Drain, where all buy stations, including wall guns, 3D Printers and Upgrade Stations will stop working for 60 seconds.
