Welcome to Reviewing the Little Boot Icon, an unfortunately named series of reviews for Reboot-modified cards. Today's review: Pheromones, a virus Noise: Hacker Extraordinaire doesn't want.
Changes: Install cost 2>1.
Pros: Cheap to install, Gabriel Santiago: Consummate Professional likes this to help him make money on Security Testing Desperado HQ. Combos with it self to get more effective every time you use it. You might even get the Corp to purge just on this. The Professor: Keeper of Knowledge weirdly also likes this to unload his Personal Workshop full of exotic programs, especially since he can tutor it with Djinn.
Cons: A purge or Crisium Grid is likely to follow your telegraphing your intention to run HQ for the rest of your life. Noise: Hacker Extraordinaire doesn't have the 2 influence for this usually, losing out on some sweet virus synergy.
6/10 Fun but niche.
