here is a tip, once you reach the underground sewer level where you face the giant worms there is a room with bugs in it (you will know which room it is, since the bugs are only in that one room in the entire game for the most part) kill most of the bugs and leave the room, make sure you don't kill all of them since they won't spawn back otherwise. this is a great way to farm for essence.. do this until you max out so you can upgrade the wooden sword to level 7 which creates the unlaboured flawlessness which is the strongest weapon in the entire game.
i think hes just posted stupid stuff like that to get his post count higher. good way to get himself banned i guess.
you should try asing one of the people in the trophy hacks sections whos done this for NGS2 anyway. if the save format is similar to the ps3 one then there should be no problems modding it.
