First, I must tell you that you must defeat Adam from the scoop "Out of Control" for any of this to work.

Ignore what anyone else says about defeating psychopaths. Some must be done a certain way, but most do not.

Adam: Have Yuu and Shinjo armed with handguns and make them hide in the store right outside the platform to the Space Rider. When the battle starts, immediately run away in any direction. Shoot his balloons. If you get lucky like me, he will get stuck in the store that Yuu and Shinjo are in. They will continually shoot, and you may not have to do anything at all.

Cletus: Hide behind the display rack closest to the right wall. After Cletus fires six shots, pop out and fire a shot at his head. Continue until he is defeated.

Cliff: Have a small chainsaw handy. Hit him once and he will run to one of his holes. Find him and do it again. Try and beat him to his hole, so you can get another hit on him before he retreats.

Jo Slade: Hit her a few times with the small chainsaw and she will go down.

Steven: Run up next to him with a small chainsaw. Swing at him a few times. If you get knocked down, just run to the shelf near the back right corner and grab some OJ.

Carlito 1: Jump up there with him and have a katana handy (you can't get a small chiansaw yet). Hack him up at close range. If he does get moving and moves to the back of the food court, get close, hack once, wait for him to throw a bomb, and run. He will be damaged by his own weapon.

Carlito 2: Slow way-Grab many guns on the way there. Hide behind a pillar so that you can shoot him but he can't shoot you.
Quicker way-Have a small chainsaw and plenty of Nectar (OJ+OJ at Columbian Roastmasters). Run by him, hack, then run away. If he hits you till you're almost dead, run into Ned's Knicknackery and drink a Nectar. Don't worry about the bee if you already have one. If not, grab it and throw it down into the group under Barnaby.

Convicts: Have the SMG from the Food Court and from the Al Fresca Plaza. Shoot the gunmen when they run into something. When he's dead. Shoot the driver.

Snipers: Chase after them with a small chainsaw. They will run. Get ahead of them and them swing. All three are quite easy to kill.

Isabella: Have a small chainsaw. Stay near a wall and move against it. When she stops to turn around, swing at her.

Sean: Hack him a few times with the small chainsaw.

Paul: Hit him as many times as you can while he is in the store. When chasing, don't try to hit him until he stops to light another molotov cocktail.

Carlito in van: During Case 7-2, Carlito will try to ram you and throw bombs at you when you are near a truck with a time bomb or that used to have a time bomb in it. Swing your small chainsaw twice. The 2nd swing will hit him. He will run away. When he returns, do this again. Hit him thrice to issue a secret event and get rid of him.

Sorry. I don't know how to defeat Larry the Butcher or Kent the Photographer. I ignore Kent and haven't gone far enough to fight Larry. I'm guessing that using a small chainsaw will get rid of them quick, though.

Hope this helps. :)

With the saucepan, it seems pretty rubbish on it's own, but, with it equippend examine a stove and wait about 2 seconds till you see it go red the pick it up, walk over to a zombie and hold X, Frank shoves the heated saucepan into a poor zombies face.

To mix anything, find a blender in one of the food stores. The ones I know of are in the food court and in the Paradise Plaza.
If you mix yogurt and something fruity, you will usually get a quickstep drink.
Mixing two fruity things will usually give you nectar.
Mix a baggett and a snack to get spitfire.

Those are all I know of right now, but I hope it helps.
