Message from Tom

The Big D demanded a tutorial be included, so here it is.

Short version: Plug this into any Institute terminal and copy the message.

Long version: PATRIOT's been sending us short coded messages for years using an evil little encryption scheme. It was a bitch and a half to reverse-engineer (PATRIOT's got skill!), but I nailed it. Put this holotape on any Institute terminal and it'll deliver a gift-wrapped message straight to PATRIOT. You're going into the belly of the beast, friend, don't trust anything.

  • Tinker Tom will provide the encrypted message holotape unless the player character has the Network scanner holotape in their possession, in which case Tinker Tom will modify it to provide the encrypted message capability. If the modified network scanner is subsequently given to another faction (Sturges or Proctor Ingram) before sending the encrypted message, a new objective will appear to return to Tinker Tom to collect the encrypted message holotape.
  • The scripts associated with this holotape and the related network scanner holotape are both named './admin.network_scan'
  • Although the encrypted message holotape cannot perform the network scan function, the network scanner holotape can perform the encrypted message function (provided Underground Undercover is active).
