A physical security feature to help stop network theft. Good thing Neural Disruptors are all physical.

A Compile Key is a single-use item which can be stolen from the Scientist in a Program Compile side-mission. It can be used to access the Research Databank to compile a random program, or sold for 150 credits.

Unlike some other special items, a Compile Key can be kept after the end of the mission, in which case it can be sold to Monst3r or used in another Program Compile side-mission.

That's got it. The code has started compiling, let's hope it doesn't take too long to finish.

A Research Databank is a mainframe device which occurs in a Program Compile side-mission.
