When typing in your name, press shift and ^ and then a number. It will delete the symbol you just wrote, and change the color of your username. The colors are:
On RESISTANCE theres a tree at the bottom left corner of your map by a place where a car is covered with a blanket and is broken and no wheels. This glitch requires a 1 person to stand right next to the tree. The next person climbs the wall and knives the tree then right after that hold your throwing knife and you'll be launched in the air hold y to put your throwing knife back. Land on the tree and jump onto the building and run freely.
First, you want to go to multiplayer on MW3 and choose split screen. Then you want to go to game setup and do the following:
Options: Bomb Time- 5 second
Bomb Plant- 1 second
Bomb Defuse - 1 second
Time Limit- Unlimited
Killcam- Off ( or you can have it on)
Max Health- Miniscule
Number of Lives- 1 life
I hope this trick will help you.
Once you hit level 20, use the Specialist package.
Make a class, give it hardline and use the Specialist package. It not only gives you extra points at kills 1, 3, 5, and 7 but also helps you complete the perk's challenges AND the Specialist Challenges for each perk.
You are completing the perks and each perk has a Specialist perk challenge to it. For example, if at 1 kill you unlock Assassin, you are completing Assassin Challenges while also completing the Specialist Challenge entitled 'Assassin.'
This equates to a boatload of XP once you start moving through these challenges. Not to mention the 200 XP per kill at kills 1, 3, 5, and 7 every time. You will be hard pressed to find a faster way to gain XP while playing any kill heavy mode.
You get EXTRA points for kills 8, 9, 10 etc. as long as you have all the perks on and have not died so it's like double XP in on itself.
First you need to buy a sentry gun and place it down then buy another senrtry gun but keep it do not place it down and buy some c4 exploseves and switch to the c4 and go to the sentry gun you placed down and pick it up but at the same time switch to the sentry gun you bought on your d pad and place you sentry gun away and you should have your other one out and put it away by pressing y and you should have an empty place for a gun. Works on any map.
Go to suvival mode and if you are on like level 50 and your friend is on like level 10 tell your friend to lend you some money if he wants slight of hand tell him to give you $5000 and if he gives it to you buy it and set it down and he can get it and if he wants a type 95 tell him to give you $3000 and buy it then pick up a gun and set the type 95 down and he can pick it up.
On the bottom left corner of Arkaden, there is a restaraunt with a counter. You can climb on the counter, walk forward, and be behind the counter. Then you should crouch and be in alot of cover and still be able to shoot people. Using this, I got the other people angry and got an Escort Airdrop. Another good place to camp is on the southern part. There is an entrance to the mall that you need to climb stairs to get to, so climb those stairs, and to the left there will be a platform blocked by glass, so break the glass and hop the rail. Keep moving until you reach the end. You may notice there is a small ledge, so break the glass and carefully climb onto it. Now move along the edge and turn 2 corners and stop and crouch. People usually are freaked out by this, so it makes it easy to kill them, but you will have no cover. You cannot access the 'Hidden Ledge' as I call it, on survival mode, but you can access the counter in the restaraunt in the bottom left corner.
So if you quickscope you should know that everybody suggests you use a bolt action. But I think it's better to use a semi automatic because if you miss one shot with a bolt action your usually dead. But if you use a semi automatic you can spray.
To get to level like fourty on the survial in the resitance is you go to the buildin in the middle and crouch behind the couch till you have save about $9, 000 minuse the preitor missle to take out the copper then you need to run the gun suplie and buy a light mechinegun to take out the juggernuts and c4 plus you need a delta and riot squad with you and a senry gun if unlocked and you'll get up to like 40 and the 1st time I did it I got to wave 45 the 2nd time wave 59 the 3rd time 44 and the final time 60 it truely works with one or two people.
I was playing survival mode on underground and I figured out a good way to make it to round 16 or over. All you have to do is be on level 15 or over get the acr 6. 8 and scar. Toy will need to buy self revine if you do not have it all ready. Next get claymores full thing of grenades full thing of flash bangs. Then you will need riot squad and you will need to buy a sentry gun only if it is unlocked if its not don't worry its not really needed. Then camp where you would buy delta squad and when all of the delta squad guys are eliminated buy it again and keep buying it you will make it to a high round. I made it to 19 my first time and 22 my second and 17 on my third and my final time in one day I made it to 21 so this strategy works. Tip: if you have riot shield delta squad buy them insted it makes it a little easier.
There is a stair case but not the on in the front of the map. So you go to the left if you appear in the front of the map, then you go down the few stairs that are there and then you enter this building then you walk down the staircase and wait for a guy to come then you knife the dude that walks in. THIS ONLY WORKS FOR THE FIRST 2 ROUNDS!
Got to sniper rifles, get the Barret Social, put the acog scope on it, get the marksman perk, quickdraw, and any other one. Make the secondary a machine pistol. Any one you like, and you should get a lot of kills!
First Round-Kill everybody with your knife and do not shoot your weapon or pick up the enemys. Second Round-Use your handgun and kill everybody and do not buy ammo refills. Third Round-Do the same thing. Forth Round-Buy a gun that you like for $2000 or $3000 dollars. Fifth Round-Just kill everybody and you can buy a ammo refill. Sixth Round-Take down the helocopter. Seventh Round-Buy a centrey gun or a centrey gernade launcher, if you have enough money buy another one and put them were you buy delta squad. Eighth Round-Buy a delta squad or a riot delta sheild squad. Just keep reapeting this pattern and you get alot of money but you have to kill people to. But buy a light machine gun too and use your other gun that reloads faster.
If you want ton's of points really fast, you have to get 2 controllers, your controller will have a riot shield, and the other will have a sentry or remote sentry and it will shoot your shield. You will get tons of points. If you have a friend that wants points you do the same thing, but both of you will have a sentry and your sentry will shoot his, and his will shoot you. But if you want to do it the easy way, you get a light machine gun and shoot the shield.
Me, and my friend were playing survival on Interchange, when we noticed something weird. We both jumped inside of a bus, (next to the grenade laptop) but the funny thing was, only dogs came into the bus. Regular enemies would not take one step into the bus. It wasn't because I killed them either. Juggs, and dogs were the two things that could get in the bus. We even managed to take down all the helicopters, the bus provided a great cover. If you're about to die, just lie down, and watch the door. My friend, and I went from dyeing at round 36, to suicide bombing at 99! I'm telling you, this works. Try it for yourselves. Enjoy!
I found the best way to get to high level 20's in dome is, when you first start run out the doorway to your immediate right and go up the ladder on the dome, then lay down right in front of the ladder, almost all the enemies will come up the ladder and you can get all head shots and kill streak bonuses, keep in mind you will get an occasional enemy from your right side that climbed up the other ladder, just look over and pick them off, after the second wave you should have between $7000 and $10, 000, run back into the brick building and buy 2 sentry guns and place them outside between the brick building and the dome all the way against the cargo containers that make a wall, 1 on each side of the forklift facing up the hill towards the enemies path, also picking up all the shotguns and getting back up the ladder, after wave 4 is done you should have about $10, 000 to $13, 000, go in the dome and buy a light machine gun and trade your shotgun for a AR, also go fill your grenades, now your pretty well armed, on level 6, 15, 24, you will have helicopters, just grab your sentries and run into the brick building placing each one in the back corners, and pick off all the enemies and save the choppers for last, if you stand in the far back corner there is a pillar that you can stand behind that you can move over and shoot the birds thru the hole in the roof and then duck back behind when they shoot back, after about 1 clip in the LMG timed right the birds should be down, then just put your sentries back outside and get back up the ladder and continue shooting the fish in the barrel, also while laying down you can shoot down thru the floor your on and pick them off before or coming up the ladder, on wave 9, 12, 18, 21, 27 you will have Juggernauts, just crouch on the edge of your platform and when the first one hits the ground from the bird above hit him with a stun grenade and empty a clip from your LMG and he's done then just stun the others and keep your distance and pick them off, NOTE: once you hit 24 the games throws everything at you LOTS of enemies and it gets tough, you will end up jumping out of your nest and running for cover else where, the farthest I've made it is to the last jugger on level 27, I was shooting the second one and the third killed me from behind... that being said good luck.
On Resistance, before the juggernaut comes, buy 10 c4's (buy c4 twice) and toss 8-10 c4's into the smoke cloud that appears when the juggernaut's copter stops. When he gets to the ground, wait till he starts shooting and then detonate.
Play 1v1 search for a player then invite him to the game right away make shure you have tacks put the tack down have the player keep killing you while still putting your tack down.
On ARKADEN go to the BurgerTown Resturaunt and go inside and jump on the silver table and go to the edge of it and there is SAM'S TEDDYBEAR!
Most people say not to pick up enemy's guns, but I disagree because I've tried the other tricks but I get farther when I pick up enemy weapons. Most people buy the same gun anyway.
On survival mode I found out a juggernaut's weakness. So if you want to try to kill a juggernaut his weaknes is grenades.
Go to dome sabotage mode. Set the bomb timer 5 seconds round time unlimited. Plant timer 1 second, defuse time 1 second, health minuscule. If you win you will be a level 8 after the first game.
Everyone says that right when you unlock a new attachment, do the challenge for it. I disagree with that. If you do that,, all your challenges are beat and you're still at weapon level 25. I do about 3 challenges for the weapon and keep using that weapon until I get to weapon level 15 then start doing my challenges. So I hope I see you with a Gold gun.
I'm a quickscoper myself. I use to suck and watched youtube videos of montages of it. So what I did was go into private macthes with my friends on xbox live and all we did was quickscope. So by doing that I kept getting better and better. People say it takes you about a year to master quickscoping it took me 2 months. So that's all I did. I use to have probelms quickscoping in public matches to I use to stress alot when I saw some one. But I was good in private matches so all I do in public matches is just concetrate and pretend they have a sniper try to do that. If your a newbey to quickscoping and don't know what it is it's just were you put your cross hears on a guy and aim in and right when you see him in your scope shoot. For a sniper I suggest Msr.
If like you like to drop shot, and usually do it in a game. I would recommend the Tactical button layout, instead of a default. If you haven't already did this you should. What happens is your knife button become crouching/prone. So you have a faster time to lay down.
So on stay sharp where you spawn turn around and you should see a jeep in the back of the jeep should be a ak74u. Later after you clear 2 areas you'll see another jeep, driving the jeep should be a teddy bear. Fyi the 2 easter eggs don't have anything to do with each other.
Get the Specialist Strike Package and kill 1 person then die then kill another person and die just repeat this 78 more times and you have Hardline Pro.
When you start, use your knife and starting weapon to kill enemys. Rounds on different maps have different specials. For example, on round 16 on Resistance, enemies use ACR 6. 8 . (they may use FAD I am not sure), but on round 16 on Arkaden, you will face regular enemies (don't know what weapon they have), a juggernaut, a riot shield juggernaut, a chopper, and dogs with explosive charges on them. Go for the Mini Missions (I. E . Headshots, quad kill, flash kill, kill streak, knife streak, and rampage) to earn extra money if you need it. When facing juggernauts, use an LMG (can be bought for $7000) or a predator missile (can be bought for $2500). As you go to higher rounds, you may notice enemies have more and more armor so be careful. Usually you can go to higher rounds if you can use Delta squad friendlies or better yet, Riot shield friendlies.
In survival you can have 2 sentry guns! Buy 1 and place it, then go back to the crate and you can buy another. This makes it easy to survive till round 20 on any map. Just go to a spot with 2 entrances. Put 1 sentry on either side and let the sentry's do the hard work. When the enemy start destroying your guns, buy a delta squad or riot shield squad. This way you can easily survive on the weapons dropped by the enemies. As for the maximum wave you can survive, it's all about how good you protect your sentry guns and squads.
I killed juagnatch by: Buying a riot shield delta squad and picking up an enemys machine gun and I put my delta squad outside by the air support |Underground! | Then they shot him and he was killing them so I shot him a whole load and he died but only 2 of my delta squads were remaning.
At the first waves, use the Five Seven and knife, (don't use the weapon the enemy has) and at wave 2 buy a Desert Eagle and use it until wave 4 or 5, by then you may have 7, 000 dollars, so buy a light machine gun (anyone is good)and if you have 2, 500 dollars buy a predator missile anduse against the helicopters on wave 6, and when you have 3, 000 or 5, 000 buy a delta squad or riot shield squad, and on round 10 use your LMG (light machine gun) against the juggernaut, and use delta squad or riot shield squad until wave 15, and that is a round with 2 juggernauts, so be careful. You should use flashbangs and frag grenades. I survived to wave 15 (juggernaut wave) using this strategy. If you need to, replace Desert Eagle with ACR 6. 8 . The Attack Dog rounds aren't hard if you use a high power weapon. If a Dog tramples you, quickly press R3.
These perks operate in addition to the standard 3 assigned to the custom load out chosen at the beginning of a match.
