Hello this is the first time I've added a hint so here goes, on the level where uve got to save the key maker, where you are in the church (i find this easier) if you antigravity jump up to the top level either the right or left youll see two statues they are holding swords pick 1 up and I find beatin smith with the sword much much easier than with just fighting him I hope this has helped someone if so please let me no thanks agian.
Ok, on the level Answer The Phone, when you first have to fight the agent...jump behind him and keep smacking with your shotgun if you have one, if not, just keep punching him. Soon he'll fall off the edge. But unfortunatley, when you jump to the next building, he follows you. Another useful thing to do is use your focus and keep taping the Y button. You'll keep in an awkward way and he'll go flying of the edge. Hope this works for you!
I don't know about you but I had a real hard time finding the anchors in the lvl 'Waterways' If any1 needs help, the anchors are the blocks that hold the big sirling pole in the ground Just shot those a coupla times and it shuld come loose
