As soon as you begin the demo take the first staircase to your right and walk up.
At the second store/shop on your left (it is a resturant/food court) enter the shop and jump behind the counter and walk to the juice section (youll see it, mmmmm O.J.) after you replentish your health,walk to the right of the juice section and jump off-trust me.
You will land on an orange canopy and yeehaw youll find the Katana that will slice and dice the hoards of zombies in your path. All though the katana does not last long, it is freakin sweet watching the zombies be cut into bloody pieces!
Note katanas are also infinite from stalls N116 and E205.
Hint: Bester Fester Beginning
Replay the first few portions of the game first -- save the couple and photograph them hugging for moola points. Kill a few zombies and then die around the parking lot area. When you "save and exit to title", you keep your characters development (and PP values) for the next attempt at the game. You can power up significantly to muscle through the later areas of the game!
Hint: Samurai Onechambara Zombie Action!
Screw the firearms. This is not Resident Evil! Stick with the samurai sword if you want to whack bosses. Deliver a few hits and your bullets can be saved for times when you need to attack at range to get to vital food and health items. Note that this becomes valid only with some bosses (not all).
Hint - Carlito Tactics
In order to beat Carlito, there are two ways I have discovered. Either go into the battle with two pistols, one of which is given to you by Brad and another you can find from a cop, or go into the battle with the sledgehammer or katana. Method one involves running through the Welcome sign and running toward the ice cream parlour, then turn 180 degrees and stand behind the boxes before you go into the seating section. There you can shoot Carlito but he cant hit you. Eventually he will run on top of the food places and you must turn and hide behind the boxes, strafing and shooting him.
Method 2 is to follow the beginning portion of one, except when you get to the boxes, run past them and climb ontop of the boxes that allow you to jump up to where Carlito is. Equip the sledgehammer or katana, then jump up when carlito is shooting at Brad or when hes reloading. Then just smash him, youll take damage, but his flurry takes down one bar of health, so you should beat him and kill him with one bar of health left.
Hint - Jeep Inmates Tactics
Head to the North Mall across the park. Inside hunt around the shops that are under construction for the nail guns. You shouldnt need more than two. Go back out to the park the way you came in and the cutscene will play. Head to the trees near the Food Court and wait for the jeep to try and make a go for you.
If you stay in the tree area, the jeep should smack repeatedly into the trees, freeing up a major opportunity to nail gun the inmate on the machine gun from a safe distance.
Once he is down, nail gun the passenger, then finally the driver. Once all three are dead you can go examine the .50 Cal machine gun and dismount it. It holds about 200 rds and is extremely powerful (I used it to kill Carlito in one small burst). It is also extremely acurate (you can lightly squeeze the trigger quickly for single shot). One of the best weapons in the game!
Hint - Park Inmate Slaughter
Nine times out of ten when your escorting any survivors through the court yard you will have to deal with the extremely annoying and deadly inmates sporting around in there little jeep. Fortunately they are a little rusty on their driving skills and tend to run into walls.But that doesnt stop the inmate with the mount machine gun from unloading on you and your party of survivors.
The easiest way to defeat them is to go to the La Frescna Plaza and grab the Sub Machine Gun hidden in the Fountain. When you step out into the court yard immediately direct your party to run to the corner immediately to your right. then run left. wait for the jeep to run into the wall(because they will try to run you over) And concentrate all of your fire on the inmate firing the machine gun. It should take about 50 rounds and hes dead.
By now the jeep should already be backing up to make another go at you. dodgethe jeep just barely and right when the red "B" icon apears, quickly examine th e machine gun on the back. Now manually aim(with the large machine gun) and make short work of the other two inmates.
Hint - Uzi Locations
There are some reliably constant sources of Uzis in the game (note -- unless you are doing Case 1.1, thses Uzis do not appear if you have one in stock already): (1)
The fountain in Al Fresca Plaza. Note, having an Uzi in stock will prevent this item from spawning when the Al Fresca map is loaded. Its best to complete the Case files until this area of the map is opened easily (assist Brad, fight Carlito #1 on day one). (2)
In Paradise Plaza, head up the stairs to level two (the stairs next to P113 Kids Choice Clothing). On the landing mid-way up the stairs, jump and mantle onto the blue store marquee. Follow the wall until you are over P116 (Shoe Kings). The Uzis placement should be obvious. (3)
In the Food Court, locate F103 (Chris Fine Foods). There is a signboard that has a cooks cariticature. Mantle onto the dining booth sidings, then mantle again onto the cariticature signboard. The Uzi should be on the top. (4)
The maintenance tunnel warehouse. This is the same room as the maintenance tunnel key. On the map, this room is underneath Leisure Park, and may be considered "just south east" of stall W107. (5)
In Wonderland Plaza in the play area by the maintenance tunnel entrance, you need to zombie ride to the toy playhouse. The uzi is on the houses roof. (6)
In the leisure park, goto the entrance of the parking lot, turn right & go to the corner there should be a tree with a rock under it, the Uzi is up in the tree. (7)
In Entrance Plaza, go near the escalators. You will need to use the Zombie Ride to reach it.
