Multi-hacks are mods which improve a portal‘s burnout insulation, which increases the number of times you can hack it before it burns out. The number of additional hacks granted by each multi-hack type is as follows:

  • Common: +4 hacks
  • Rare: +8 hacks
  • Very Rare: +12 hacks

If you have more than one multi-hack deployed on a portal, only the rarest one will function at full effectiveness; the remaining ones will be half as effective as they would normally be. The chart below shows the resulting number of hacks from every possible combination of installed multi-hacks:
