This map shows the locations of all 16 QR Codes that are scattered all over Chicago in Watch Dogs. After completing this, you should  get the "Read Only" Achievement and the "Gangster Assault Rifle". Also, if you scan these codes using your phone you'll get a secret message.

1. The code is found on top of the Food & Liquor building near an intersection. Head down the street to the south of the code and hack a low hanging camera just above two garage doors. Turn the camera to the north and scan the code.
2. This one is just a short distance to the north from the first. When approaching the code from the south, you'll see it on the right hand side next to a For Rent sign. Turn down the alley to the left before you reach the QR code. You'll find the camera on the corner of a historical looking building on the left side of the alley.
3. This one requires a boat. Head to the west end of The Wards, near the dam on your map. You'll see the code if you look from west to east. Look for a camera posted on the dam, hack it and you can scan the code.
4. The QR code that you're looking for faces west, so approach from the east and stop before you get to the gun store. If you pass the gun store you've gone too far. The camera you need to hack is located on the south side of the road, high up on what looks like an old apartment building. Hack and face it to the east to scan the code.
5. This one is located on the southwest end of the bridge on the large Tidis building. Move to the east end of the bridge and hack the camera on the corner of the building. Use the camera to scan the QR code.
6. You'll find this code on the side of the building with the Safe Energy Saves You Money billboard. Head to the gas station to the northeast of the building, hacking a camera sitting on a light pole. Scan the code to hear the audio log.
7. Head to the nearby train platform and go up top. The station is to the east of the QR code which sits to the side of another Tidis building. While standing on the west stairs leading up to the platform, hack a camera that sits on the corner of the building. Doing this will allow you to scan the QR code.
8. When you reach the location of the QR code, head to the east, past two buildings. You'll find the camera you need to hack sitting on the corner of a building, Scan the code.
9. Head below the train platform that is just barely to the east of the QR code. Head to the north stairs that lead to the platform but don't go up these steps. You'll find the camera you need to hack on the wall to the east, then scan the code.
10. In order to find the camera you need to hack, go below the freeway, finding yourself on the northwest shore where the three rivers meet. The camera is under the freeway. Hack it and aim it back toward the southeast. You'll find the QR code under the freeway.
11. Head to the train platform to the southwest of the QR code. Wait for the trains to pass, then jump up on the tracks and head to the northeast, following the bend to a platform off the right side. Hop up on top of the platform, then hack the camera high up on the wall. Point the camera north to find the QR code.
12. This code is smack dab in the middle of a four-way intersection of an alley. When you get to the center of the alley, head down the northeast wing of the alley, hack the camera on the wall, then scan the QR code.
13. You want to head to the east of where the code is actually located. You will find the camera you need to hack far up on the wall of a building, across the street east of the Chicago Water Tower. Two cameras sit nearby and it's easy to hack the wrong one. You'll know you have the right one when the code pieces together to the west.
14. This code is extremely close to one of your fast travel points. Head to the area and into a parking lot where you will find a garage door you can hack. Hack the camera above the door on the building to the right to scan the QR code.
15. You need to be on the west of the code and across the street. Find a camera high up on a wall, point it to the east and find the QR code to the right of a billboard with a car on it.
16. This is the only code in Pawnee, so it won't be hard to find. Head for the broken bridge and drive onto it. Hack a camera on a light pole and then look toward the billboard. Scan your final QR code.

Hope this helped >_<

PVP (Player VS Player) is a way of how Players test their skill with other Players in Minecraft, not only their Building skills but also their Combat skills. When a Player is playing PVP with another Player, there are a few tricks that you need to know that would make you Win easily. (Note: Some of these tricks may require some practice to implement it perfectly on the Battleground. Youtuber OMGChad made a short video about these tricks. Don't forget to subscribe to him

Use these Commands to summon secret Mobs/Entities that you will never find anywhere in Minecraft

• Tamed Zombie Horse

/summon EntityHorse ~ ~ ~ (Type:3)

• Tamed Skeleton Horse

/summon EntityHorse ~ ~ ~ (Type:4)

• Giant Zombie

/summon Giant

•  The Killer Bunny (spawning this mob in survival is dangerous so spawn it at your own risk)

/summon Rabbit ~ ~ ~ {RabbitType:99}

Hope you enjoyed :-)

Here are some things you might/might not know about Minecraft

1. You can flip animals upside-down by naming them "dinnerbone" or "grumm"
2. Zombies and Skeletons don't burn on soulsand
3. You can make lava and water stream together by placing either one 1 block higher than the other
4. Cactus can destroy items
5. There is 1 in a 10.000 chance that the title screen will say "Minceraft" instead of "Minecraft"
6. You can place paintings over doors and walk through them
7. You can make sheeps change their colors constantly by naming them "jeb_" (must have the underscore)
8. You cannot see a players name through a chest even if they are not crouching
9. A creeper's body model is actually a glitched version of a pig's body model. But because Notch liked the look of it, he gave it a green color and a creepy sound, thus the famous creeper was born.
10. In an unused area for the zombie pig man texture, the words "THX XAPHOBIA" can be seen. This was written by Notch to give credits and thanks to the original creator of the texture, XaPhobia.

You can change the color of the beams on your beacon by using stained glass. The colors can also be combined by using multiple stained glass.

<== You have to put the stained glass on top of the beacon

You can also make the beacon constantly change its colors by using redstone contraptions

watch this video to know how to make it.

Team Fortress 2 

• Heavy gunners sometimes say "cry some more" while in combat, likely a reference to the same line spoken by the heavy weapons guy.

Papers, Please 

• A message pinned to the wall at the border checkpoint contains a modified version of the first day's orders from Papers, Please with references to Arstotzka changed to Kyrat.

Predator 

• During the last mission of Hurk's redemption he will instruct you to go to the helicopter he marked on the map, then referencing a movie quote, "get to the chopper!".

Star Wars 

• The signature weapon HS77 is modeled after Han Solo's blaster from the Star Wars movies. HS77- Han Solo 1977, which happens to be the release year of the original Star Wars movie. Also in the guns description, "for quicker handling to ensure you always shoot first." Referencing the long contested debate of who shot first,Han or Greedo.

Honey Badger Viral Video

• During the survival hunting quest involving De Pleur's slum infested with honey badgers, the soldiers fighting with you will reference the youtube video with dialogue stating that, "They just dont give a shit".
• When hunting the rare honey badger, Ajay says, "That thing just didnt give a shit" referencing the online video.
• Reference : https://www.youtube.com/watch?v=4r7wHMg5Yjg

Alternate Endings 

• At the beginning of the game, after Pagan Min has abducted the character and Darpan for a "dinner party" in De Pleur's fortress, it is possible to get a different and early ending to the game, created as a joke by Ubisoft. Once Pagan Min has left the room and told you to stay, if you wait at the table for roughly 15 minutes, he will return to the room and take you to a shrine to scatter the ashes of Ajay's mom. Once you are done at the shrine he will escort you back to his helicopter. The credits then roll.
• Either within the first alternate ending, or in the regular ending, if you don't shoot Pagan Min, you can shoot his helicopter after he flies away after the shrine scene. This will create a new unique location of the helicopter crash site. You can go to this crash site after the credits. You will find the corpse of Pagan Min. When you loot him you will find his golden pen and 250.000 credits.

Various 

• After finishing all Yogi and Reggie missions you will receive a pipe from them. You will finde the pipe on a desk next to the door inside the Ghales house. If you use the pipe, you will suddenly wake up in a random location somewhere in Kyrat. This location will change every time.

Speed and the Matrix 

• In Hurk's last mission, the player is instructed to rescue Hurk by flying in on a helicopter and hijacking a truck (via the "vehicle takedown" skill, which is the only necessity the player needs for the mission), then drive the truck through a series of waypoints while maintaining minimum speed, or the truck will explode after a few seconds. At the end of the mission the player is instructed to jump out of the truck and let it explode. The entirety of the mission is a reference to the movie SPEED, where a bomb was placed on a city bus, that would explode if it dropped below 50 Mph. Hurk even references the actor from the film, Keanu Reeves, as well as another movie Reeves was in (The Matrix) when Hurk says "Dude! Be, like, my Keanu man. You can fly, right?"

Gladiator 

• In the arena the announcer might say "Are you not entertained?" which is a reference to the movie "Gladiator".

Robocop 

• The description for the A.J.M Pistol states the weapon "was last seen patrolling the streets of Detroit" and its name A.J.M. stands for Alex.J.Murphy who was the man who became Robocop

Tool durability

The values in this table are the number of useful actions that a tool can perform.

	Gold	Wood	Stone	Iron	Diamond
Durability	33	60	132	251	1562

Gold tools destroy most blocks faster than any other type of tool. However, they can only collect blocks that can be harvested with wooden tools.

The next table shows how many uses remain in a tool, at the first moment its durability bar appears empty.

	Gold	Wood	Stone	Iron	Diamond
Durability	2	3	6	10	61

• Using a sword to mine blocks (including some for which they are the fast tool) counts as two uses.
• Using a pickaxe, axe or shovel on the wrong type of block only counts as one use (but is slow), but attacking mobs counts as two.
• A hoe does not lose durability either mining blocks nor attacking mobs (but in either case, it's no better than bare hands). Its durability applies only to tilling dirt.
• Carrot on a Stick has a durability of 26, Flint and Steel and Fishing Rods have a durability of 65, Shears have a durability of 239, and Bows have a durability of 385.
  • Like a hoe, each of these use durability only when used in their normal fashions.
  • Successfully catching a fish counts as one use of a fishing rod, reeling in the line while it is stuck to a block counts as two uses, and reeling in any mob counts as three uses. Casting into water and reeling in an "empty hook" does not cost durability.
  • Shears are only damaged when shearing a sheep and when breaking cobweb, leaves, tall grass, tripwire, and vines blocks.
• Items with an Unbreaking Enchantment do not always lose durability when used; for a given enchantment level, the chance that they will use durability is 1 in (1+level). The result is that they will last an extra level times their original durability, give or take a few.

Armor Durability

Armor durability is based on your armor types(head, torso, legs, feet) and materials(leather, iron, chain, gold, diamond) of the armor that you're wearing. Every time you take damage, you lose 1 point of your armors durability.

Armor durability only decreases when the player is taking damage from:

• Direct attacks from players or mobs
• Getting hit with flying projectiles(snowballs, fireballs from either ghasts or blazes, arrows, etc)
• Touching blocks that can harm the player(lava, cactus, or fire)
• Explosions
• Thorns enchantment

Armor durability does NOT decrease when the player is taking damage from:

• Suffocating
• Drowning
• Taking fall damage
• Falling into the void
• Poisoning
• Damage from potion of harming
• Ongoing damage by being on fire

The Table below represents the armor points of each armor pieces based on their materials

	Leather	Gold	Chainmail	Iron	Diamond
Helmet	56	78	166	166	364
Chestplate	81	113	241	241	529
Leggings	76	106	226	226	496
Boots	66	92	196	196	430

This Glitch still works on Minecraft PE versions 0.9.0 - 0.10.4

All you need to do is just follow these instructions:

1. Make a small chest (I don't know if it works with the Large ones)
2. Put all of your items in another chest (put them all in your normal items chest, but not the chest you're going to use for this glitch) But keep the item you want to duplicate (only 1 item)
3. Put the item you want to duplicate in the small chest
4. Go back to the menu screen (not the home screen)
5. Go back to your world
6. Take the item from your chest
7. Quit the game
8. Remove the game from your Taskbar (The Multitasking bar)
9. Play Minecraft PE
10. Go back to your world and take the item in the small chest(There should be another one in your inventory and another one in the small chest)
11. Then if you want more, press and hold on the empty box beside your item's box in the quickbar
12. A "Pop" sound should play and another one of  your item (the same item) will be thrown out of your inventory
13. Repeat Step 11-12 until you've reached the amount of items you wanted
14. After your item is full, repeat the whole step

I hope this trick was helpful to you

      

Here are some of the Easter Eggs i found while making this Blog:

Talking Moose

A talking moose head can be found in many locations in Watch_Dogs, such as in gun shops or bars. The moose could be a reference The Evil Dead II, in which a possesed moose head will begin to laugh maniacally.

Raving Rabbids

• Remote controlled Raving Rabbids robots can be found throughout the game, including newsstands and homes.^[1]
• At a newsstand in the northeastern part of the Parker Square district, near the location of the "Made Man" Convoy side-mission.
• During the "Big Brother" mission you can find a Rabbid in Jackson's room at Nicky's house.
• There is one during the first mission in the Pawnee district in Act 3, behind the bar in Jed's.

Aisha Tyler

• During the Campaign Mission "A Wrench in the Works", Aisha Tyler can be seen talking to another NPC. Aisha is a well-known voice actress that has worked on many films, TV shows, and games, including Halo: Reach andGears of War 3. She also appears in a hotel room or lounge talking on the phone. There is a City Hotspot in theCity Hall building in the Loop district, and near it an unmarked 'intrude' console you can hack. Do so to watch Aisha on the phone talking about farts and being followed.

Rapping fish

• A singing wall-mounted trout can be found in the 'Texture Patch' clothes shop, in Parker Square district. Walk up to the fish and enjoy the song that follows. The fish is likely a reference to Gears of War 3, in which a singing trout can be found on a wall.
