fozzy404,after you beat the game it just become a freeplay version,when you can just go explore,nothing else new to do and re-do any missions you like,but yes,the d-dub team should have added an option called,unblock all areas,meaning you can get Inside ANY places/houses/building,you like,exploring new spaces and even new missions,only you can acess if you complete the game and being able to get Inside the restricted houses/buildings.
