Chrome 2 reference
Play the "Born To Be Wild" quest. Enter the hotel and talk to Mike Davies. Then, move to the next room with the workbench. Enter the next room with a computer to reboot. Look at the wall to the side of the desk with the fan on it, to see a Chrome 2 poster.
Duplicate weapons
Note: The following tricks required an unpatched version of the game.
Throw the weapon that you want to duplicate. Before it hits the ground, press Up. Then, choose to drop the weapon that is equipped. Exit out of the menu and pick up both items. Repeat this as many times as desired. Sell them for easy money.
For example, if you have a "Deathstalker Zed's Demise" worth $7,350 and if Jin is available, empty your inventory save for the sword into storage. Go to the nearest shop. Once there hold L1, then hold Triangle and press R1 to throw not just one weapon but two. Pick up the discarded weapon and repeat the process. Sell all but one of the copies of the weapon for easy money. Doing this can also copy "sticky bomb knives", though occasionally one of the bombs will explode. Note: This does not work on grenades, guns, or building materials.
Note: This trick does not work with projectile weapons. Hold L1 then hold R1 + Triangle. If done correctly, there should be two of the same weapon on the ground and it will show that you threw and dropped the same weapon. This can be done as many times as desired. You can use this trick to make money in game or in online play, and you can supply teammates with powerful weapons. You can also duplicate a weapon instead of repairing it. Note: This also works with modified and upgraded weapons.
Easy "10 Heads Are Better Than 1" achievement or trophy
Have the assault rifle which is acquired during the second part of the game. Jump on a car and wait until the zombies are next to the car. Then, just shoot their heads. Even if you get killed while doing this, your head count does not reset as long as you do not kill a zombie by any other method except a headshot.
Easy "How many days exactly?" achievement or trophy
Disconnect your online connection, go to the system settings and advance the system date by one month. Resume the game while offline to unlock the achievement or trophy.
Easy "Military-Industrial Complex" challenge
While doing the "Bitter Return" mission there is a mounted machine gun on the balcony of city hall. Mount the machine gun and fire away. Every bullet fired counts towards the "Military-Industrial Complex" challenge. Keep shooting and you will complete all four levels.
Easy "Oh, No You Don't" achievement or trophy
This can only be earned with Sam B, and after unlocking his Tackle ability. Play Chapter 16, "Locked Up". Once you get to the checkpoint where you have to "Find another way to the cell block control room", you must go around to get to the control room. When you open the door to the cell blocks, there is a stairway going down and there you will see the Ram. Let him follow you upstairs and go back in the hallway. Leave the door open. The Ram will try to ram you down, but he will not be able to get past the door. This is where you can weaken him until his life is close to dead. Then, deliver the final blows with you Tackle ability.
Easy champagne
In the Slums there is an abandoned building at the bottom of the map. Once cleared out, you will be able to quick travel to there. In the back of the building are two rooms. Each has a fridge that may contain a bottle of champagne. If not, quick travel to another area then quick travel back as many times as desired.
Easy experience
Reach Ope's Cave in Act 3, then use the "Duplicate Weapons" glitch to copy your most valuable weapon. Sell the weapons to a vendor to get a lot of money, then buy Oleander from a vendor if it is available. Taking as much Oleander as you can buy, fast travel back to Ope's Cave and turn it in to the tribesman that give you the Continuous Event "Dreamtime". Each time you turn in five Oleander Blossoms, you will receive $1 and 1,000 experience points. Repeat this as many times as desired.
Easy money
Use the following trick if you want to modify, repair, or create a weapon but are short on money. If the craft table is inside of a store, search the cash register. Occasionally you can find a couple hundred dollars.
Reach the City and have already discovered the Church and the Warehouse. Go to the Warehouse and obtain the hammer and baseball bat. Fast travel to the Church and sell them for about $400. Return to the Warehouse and repeat the process as many times as desired.
Getting kills without dulling your weapon
Killing zombies takes a toll on your weapon. However when it is on its last legs it is not completely useless. Throwing your weapons can damage enemies without dulling the weapon. If you have a weapon worth keeping, but it is almost used up, keep throwing it at zombies until you can repair it again.
Hidden provocative photographs
In Act 2, enter the mayor's office in City Hall before it gets attacked by zombies. Knock down the painting on the very back wall in the room behind the desk. You will find three photos of a semi-nude blonde woman.
I am legend and Crysis 2 references
I am legend:
Scattered throughout the island there is a magazine with a bald woman on it. It is the same woman Will Smith captured and experimented on. The only difference is that she had a cure in her and the cure in this game would be a nuclear explosion. (lol)
Crysis 2:
In the medical station, on the roof in the radio hit and the fast travel station is, when you walk through the door turn right towards the lockers and there will be a posting bored with a ad for "Chrome 2". This is a reference two the suit in Crysis 2.
Killing humans
This trick works best if you play as Logan. Humans can use weapons, and so can you. However when it comes down to a gunfight you are both evenly matched. A good way to kill humans with little effort is to throw modded weapons. However, there are a few exceptions. The weapon Must be a sharp weapon. Blunt weapons only damage them slightly. The military machete works best. The weapon must have either a Poison mod or a Shock mod. Fire will not do anything. Make sure you upgrade the weapon to at least level 3. You may want to mod a powerful weapon because it will have minimal affect against stronger humans. Keep your distance when throwing, and have plenty of ammunition. This is one reason why Logan is better for this, because thrown objects can come back to him. However, if you have a clear view of the target, throw the weapon and they will die instantly.
Killing large groups of zombies
When you encounter large groups of zombies or have ran and have a lot of them following, use the following trick to deal with them. Look for a nearby vehicle and sprint to it. Jump on top of it and crouch on the hood. While there you can still hit the zombies. Note: Do not do this on the roof of the vehicle; you will not be able to hit them, and they can still hit you rarely. Note: Use the analog style of fighting to do more decapitations and swing your weapon faster.
League Of Legends reference
Shortly after the Lifeguard Tower (Exodus) is completed, there is a quest giver in a bungalow to the left of the main road named Annie. She initiates the quest by saying "Have you seen my bear?" and asks you to retrieve the teddy bear for her. In League Of Legends, there is a champion also named Annie. In that game, Annie's catchphrase is "Have you seen my bear Tibbers?"
Lost reference
Do the quest to clear out the Lifeguard Tower at the start of the game. Clear the garage of the few zombies there. Go inside and you will hear a radio broadcast of an Oceanic Flight in an emergency descent to an island due to engine failure.
Pimp My Ride reference
Do the quest near the end of the Resort level, where you take the big truck to the mechanic to turn it into a homemade tank or fortress. While talking to him, just before you have to defend the shop while he does his work, he will say that he is going to "Pimp your ride".
