When the guns fell silent, there were no signs of scourge energy signatures left on the planet at all. All of the Mecha had slowly been brought back online, though the Light Mecha were operating on backup power packs since they couldn't be rebooted in the field without a technician. The pulse that had disabled everything seemed to have caused them some actual damage beyond overloaded circuits.
The Super Heavy Mecha of the First Battalion would need some repairs as well, as the Crystal Matrix Power Plants that they had been retrofit with, based on the ship's engines aboard Terminus, had been blanked, and new crystals would be needed to get them back online.
The lockers did give a good idea of what upgrades would be needed to repel future attempts by the Scourge to deploy similar weapons though, and it was so ridiculously simple that Max was surprised that they hadn't done it by accident.
