Call of Duty Modern Warfare 2

First you have to unlock the gun you want to put it on and then either the silencer, like any other attatchment is already unlocked, or you will unlock that in time too. Maybe you just have to level up.

Those people have hacked the game.

Certain Prestige challenges. I think they are from Killstreak challenges in the prestige section. I have the Gold/Green diamond one, from Predator Missle kills I think (1000)

once u reach level 4 u get to create a class. Pick class 1, then it shows perk 1, perk 2, perk 3. Press on perk 1 to pick something u like. U can do the same thing with the other 2 perks. U get new perks once u start leveling up. For example bling is unlcoked at level 22 and it lets u have 2 attachments on ur weapons

To get nuke u need 25kills or 24 if your have hardline in a row without dying

You don't.

Sadly, no - nukes were left out of Black Ops 2. However, the Hunter-Killer Swarm bots (paper airplanes with explosives) when achieved as a scorestreak, is a backbreaker itself, and it won't end the game.

Essentially, Treyarch has taken away the ability for any player or team to end a game prematurely or on their own terms. You either play through to the end of the match, or leave.

The only holdover reference to nukes is the Nuclear Killer achievement/playercard, requiring you to get 30 kills in a row without dying (no scorestreak kills; gun, knife, or explosive kills only).

Well, when the nuke is set off, ( Makarov is the one who did this) in 2012, it kills basiclly everyone exept for Makarov and Yuri. In MW3, you know before this is explained in the mission: Blood Brothers, That Yuri knew Makarov. When you are Let. Price, back when he was't Captain yet, when you snipe Imran Zahkea, Supposeovlly in one of the trucks, is Makarov and Yuri. Back into the explaination in MW3. When Price now knows that Yuri "betrayed" them, he is extreamly mad. Yuri explains the rest of the story, leading into the third mission of MW2. HE explains that before they set out to kill everyone, that Makarov knew that Yuri betrayed HIM. So Makarov shoots Yuri, in the stomach, thinking he is dead. He is not, but gets replaced by undercover CIA agent, Prv. Allen. They go through the airpost, leading to the end where Makarov shoots Allen, killing him. But before this, Yuri makes it to the elevator just in time, and is found by medics, that find out he is still alive. When Price hears the whole story, he is still mad a Yuri, but lets him live.

if ur a hacker u have to have a burnt disk other wise it cant be stopped

I think you have to get 55 kills

yes

you need to get 5 tactical nukes

mad cow desease some one made a burger out of a cow and be came a zombie and it spreaded

First, make a wall of wood

then, cut a hole on the top of it

after that put rubidium in the bottom

and then add thermite to it.

then finally add metal to the top of the rubidium

put sparks on the metal then you are done

Only 2 countries have nukes that can travel all across the World. Russia and The United States of America.

No, sorry. They have a map called Nuketown, which is based off of old nuclear testing sights, that gets blown up at the end of every match you play but you can't use any nuke's like in MW2.

plutonium & weapons :)

A tactical Nuke ends the game and kills everyone

no it is not illegal. it simply pisses people off. i suggest using a silenced weapon, one man army, cold blooded, ninja. you obviously also need tactical insertions

The AA12 has a 8 round magazine.

Well i don't think so as i think fmj will only work on the assualt rifle not the shotgun

Nothing. You destroy the whole map. If you are really curious why the Infinity Ward game makers put tactical in front of almost anything, ask them.

1 man army on all of your classes, and a different class for every situation (sniper + stopping power; claymore + danger close; grenade launcher + frag grenade + danger close; hardline class to switch to when 2 kills from a killstreak; stealth class for when air support is up; etc.)
