Portals seem to be reacting to the influx of new recruits post #Cassandra. AP for upgrading Portals with a Mod is back. Agents now gain 125 AP by deploying a Shield or Mod, and each Agent can deploy 1 Mod per Portal, until their Mod is destroyed. Since Mods are permanently attached to the Portal until destroyed by the enemy, make your Mod choices carefully.
