There are six kinds of portal mod.

• Defensive mods make it harder for enemy players to kill your portals.

  • Shields reduce damage from enemy attacks.
  • Force Amps make portal counter-attacks twice as strong.
  • Turrets used to make portal counter-attacks stronger. They don’t do much any more.

• Hack mods help you get more items from a portal.

  • Heatsinks reduce how long you have to wait between portal hacks.
  • Multi-hacks let you hack a portal more than four times in a four-hour period.

• Link Amps extend linking range, so you can link to portals that are further away.
