How To Get Money
There is a really easy way to generate tons of money in a very short time.
All you need is a melee weapon. The higher the value, the more money you will make. Simply hold the ‘Aim’ Button (L1 on PS3, LT on Xbox 360). Now hold the ‘Drop Weapon’ Button (Triangle on PS3, Y on Xbox 360) and press the ‘Throw’ Button (R1 on PS3, RT on Xbox 360).
The weapon will be duplicated and you can sell it unlimited times. You can do this anywhere, anytime.

How To Get XP
The shown trick will help you to generate a lot XP in a short time with minimum effort. 1000 XP every 3 seconds. Sounds good, doesn’t it?
There are 2 basic conditions you have to fulfill:
a) Reach Ope’s Cave in the Main Plot
b) Find a merchant who is selling Oleander
In the beginning you have to duplicate your most valuable weapon and sell the copies until you have a great amount of money. It appears to be kinda random, but the merchant in front of the lighthouse is offering Oleander. Check out some other merchants or leave the game if you can’t find any reseller. Buy as much Oleander as you can and travel to Ope’s Cave. There should be a warrior who is giving you the ‘Dreamtime’ Quest. Now you can trade in 5 Oleander for 1000 XP.

Knock, knock
Breach a locked door with the first blow.
Well, this one is actually very simple. You can make this your first trophy / achievement. Right after starting the game you will have to breach through a door. Just make sure that you hit exactly the middle of the slider. It might take a couple tries, but you can keep reloading the game.

Can’t touch this
Use a hammer to kill a series of 15 zombies without taking damage.
You will want to get this done in the beginning of the game. Chapter 2 will be a good choice. Zombies will be slow and easy to kill. You can find hammers practically everywhere. Mine was dropped by the stronger zombie you have to kill at the end of Chapter 1. You might want to upgrade your weapon to get a better chance on instant kills. Remember that you can always sell stuff to get some extra money for repairing or upgrading your weapons!

Oh, no you don’t
Kill a Ram using tackle skill
First of all, you will need to play as Sam B. You will encounter your very first Ram-Zombie in the beginning of Chapter 6 – when entering the town. If you have already finished this chapter with Sam B you can reload it in the ‘New Game’ Section. Your weapons don’t really matter. Wait until the Ram runs against a wall and attack him from behind. Begin to use the tackle attack when the health bar (red bar over the enemies head) is very low. Make sure to attack from behind. Otherwise you won’t deal any serious damage. You are allowed to die which will make this relatively easy.

Light my fire
Set 10 zombies on fire simultaneously
This one can turn out to be very annoying. One of the best spots to get this done relatively easy is the very south of the city of moresby. There is a huge canal that will end at the beach. On the East side is a large group of zombies. Should already be around 10. To make sure you don’t waste your time and Molotovs you should try to attract a couple more zombies. Go in little circles around the zombies until they are close together. You might want to throw some Meat Bait to round them up. The Molotov will finally bring light into the dark.

10 heads are better than 1
Kill 10 zombies in a row with headshots
Get a weapon that deals great damage with single rounds. Pistols will work perfectly and can be found pretty early in the game (e.g. during a story quest after entering the city of moresby). You should have at least 30 shots. The earlier you do this, the easier will it be. So you might want to reload a previous chapter from the ‘New Game’ Menu when you have too much trouble with it.
To have some easy targets you should go back to the lifeguard tower. Damage the zombies and kick them down. Once they are on the ground it will be easy to aim on their head.
