This update will introduce a series of "Notorious Hideout"'s which will permit those with notoriety level greater than 5 (professional) to quick travel between notorious hideouts. Suspects cannot enter properties which require notoriety, neither can police.
There will be 6 Notorious hideout, one in each county (LS, RC, FC, SF, BC, LV) and you can travel to all of them from within each using /notorietytravel and a dialog will appear to travel.
This will be apart of RS5.1.15d*.
