On the level view of Innocence( I think that's it, or this might be the level with his family.) Anyway, on the level with bum following you, your objective is to get to the other side of the graveyard with the bum alive. Throughout the level there are various gates placed by starkweather that will prevent you from going through them. To get through the gate all the hunters in the area must be killed, and the bum must be right behind you.

Only then will starkweather open the gate, and let you pass to the next area of the level.

Oh, and when you tell the bum to stay, watch and make sure he goes into the shadows, not near them like he usually does. He's nothing like the journalist on the level press coverage(who loves to walk into gunfire, and fall to the ground and start shaking like Ashley from Re4.) But he will go stand somewhere, and there will be a shadow right behind him. Then people will shoot him/stab him, and he'll stand there, drunk as ever.

If he does happen to stand near a shadow you can fix this problem for him. Either walk as far as possible into the shadow, and tell him to follow you, then tell him to stop when he's in the shadow. Or, run up against him, till cash manages to push the fool fully into the shadow, that way he'll be safe, and you won't get a game over.

On the level cover the press( something like that.) You have to protect the journalist till she gets to her apartment. Before confronting the police, make sure she is in a safe place, in the shadows. And make sure you tell her to stay there, because if you don't she will run out and go up to the police, and get herself shot.

Also, watch out for the timer in the top right of the screen. When that reaches 0 she will run to you, and if your trying to sneak up to someone then they will hear her, and mess up your plans.

Just make sure you tell her to stay, and don't leave her to far behind.

Piggsy is the boss on the last level Deliverance. He is a big guy wearing a pig's face, and is learning the art of killing people with a chainsaw. To hurt him, you have to run around the building finding glass shards, or wooden stakes to stab him with. Now to kill him, you have to lose him, so go find a dark area, and hide in it. When he comes around, wait till he turns his back then do an execution move. Do this process 2 more times, and he should cut through a locked door with his chainsaw.

Follow him, and go through the door. Now he should be facing a door, crouching down. Throw the brick that you should have, in the opposite direction. He should go running after it, if not run. When he's a ways away, run through the door, and head up the stairs. Piggsy should now be following you. At the top of the stairs will be a door, and a hole covered by a fence on the ground. Lead piggsy over to the hole so he's standing on it. The fence should shake, and he'll run back down the stairs. Get him to follow you again, and go back to the hole, and lure him to the fence/hole. He'll stand on it, and it'll break, and he will fall all the way to the bottom. Thus, killing him.

Then After you get his chainsaw, go over to the door, and activate the chainsaw by holding X. IT should show some soldiers, and Starkweather, on the other side of the door. The soldiers will come out so run back down the stairs to the area where you first met Piggsy. Corner one of the soldiers, and kill him, then take his gun. Then bust some caps into the other soldiers until there all dead.

Then get the Chainsaw again, and go back up the stairs to the door. Hold X and chop the door down, and go to face Starkweather.

The man is so easy that it's laughable. Just hold X to activate the chainsaw, and run up to him, to kill him. It will show a scene with Cash slicing Starkweather's guts out, stabbing him through the face with the chainsaw, then planting it in his back. A job well done.

Now sit back and watch the ending. And give your self a pat on the back, you just massacred a crap load of people, and you stabbed someone through the face with a chainsaw. Then after watching the credits, go out and rent Manhunt 2.

Hope the strategy helps.

In grounds for assault, the zoo level against the Wardogs, just before you enter the park there is a toilet block you have to go through.

Inside is a door that is easily passed without being seen and it is locked with a chain.

Later on in the level, you get a crowbar to get to the last part of the level but if you go all the way back to the toilet block.

Open the door in the middle of the toilet block with the crowbar, inside is the shotgun, and it certainly helps in the last part of the level :D
