@ iamtulipin well for the HIDDEN EVENTS as the name suggests,the events r hidden on the MAP,so wen u get the message that "there is sum action goin' on in the BEACON HILLS area,jus give me a call wen u reach there"
jus go to the area and u will hv to self search those events by urself, there is no other way to track the position of those events, bro
the places where u will usually find those events are the places that r off the main road eg: the parking lots,closed and unused shops,beneath flyovers etc....
HAPPY HUNTING !!!!
cheers n peace.......
