Master Key GUIDE

Understand Master Key

Useful when…

  • Open nearby lockers after completing a hack.
  • Use a fixed-effect Parazon mod without investing in rank upgrades.

Effect and trigger

After hacking, Master Key unlocks five lockers within 20 m. The effect requires a hack and applies to lockers within that range; the supplied description does not specify a duration. It is a standard Parazon mod with universal polarity, zero base drain, and maximum rank 0.

How it fits a Parazon setup

Its listed effect is locker access, so consider it when that utility matters during missions. Live Wire instead shocks enemies within 20 m while hacking; Runtime grants +75% sprint speed for 15 seconds after hacking; Untraceable grants invisibility for 15 seconds after hacking. Those effects have different purposes and triggers.

Rank and listed sources

Master Key has only rank 0, so there are no rank-up steps to fund. The supplied source list names Rotation C on Ceres/Hapke, Earth/Cambria, Mars/Arval, Mercury/Suisei, Phobos/Grildrig, Phobos/Shklovsky, Venus/Unda, and Venus/Vesper, each with a listed 8.6% chance. These are listed source chances, not a guarantee of current availability.

Limitations and tradeoffs

  • The effect depends on hacking and nearby lockers being within 20 m.
  • Its listed benefit is locker access rather than the enemy, movement, or invisibility effects listed for other hacking mods.

Common mistakes to avoid

  • Expecting lockers to open before hacking or outside the 20 m range.
  • Searching for rank upgrades when the mod is fixed at rank 0.
