Heat

Heat represents that amount risk your currently engaged in. Taking less legal contracts, selling bud through a dealer, or growing more plants than you’re allowed generates heat. Low levels of heat typically aren’t a problem but carrying high levels of heat can lead to increasingly frequent and severe fines, protestors, DEA raids/shutdowns, helicopter fly overs, etc. Heat is kind of analogous to your Wanted Rated in GTA (1-5 stars). Accumulating too much heat and getting shut down is one way to lose the game.
