here is almost everything that you need in mw2
Step 1: Primary Weapons
First the Primary Weapons
- Assault Rifles (1 - 9)
- Sub Machine Guns (10 - 14)
- Light Machine Guns (15 - 19)
- Sniper Rifles (20 - 23)
+ riot shield
Step 2: Secondary Weapons
this are the secondary weapons:
- Machine Pistols (1 - 4)
- Shotguns (5 - 8)
- Handguns (9 - 12)
- Launchers (13 - 17)
Step 3: Equipement
Description: You only get 1 cookable frag grenade. You can "cook" a grenade by holding down the throw button and waiting for a while. After you throw it, the grenade will explode much faster and that way you have a better chance of killing someone. Frags can easily bounce and roll downhill.
Unlocked at level 4.
Description: You get 1 Semtex grenade. It can't be cooked like a frag grenade and the throwing distance is much shorter. Semtex grenades have a blinking red light and a loud beeping sound, which increase as it's about to explode.
These stick to almost anything, even on other players. Use these against Riot Shield users, it's a certain death to them.
Unlocked at level 4.
Description: You only get 1 knife, but it's a one-hit kill, if it hits. Hold down the throw button to get an aiming reticule, after that release the button to throw the knife.
Throwing Knives can be picked up and used again, so don't loose it. The knife travels in an arc and isn't meant for long distant throws, not accurate ones at least.
Unlocked at level 7.
Description: Light the flare and drop it on the ground. When you die, you will respawn next to the flare, which will disappear, so remember to use another one. Tactical Insertions can be picked up and used on another spot.
Flares can be easily destroyed by the enemy, so remember to hide them well. Friendly flares are green and enemy ones are red. Use the SitRep perk to see enemy Tactical Insertion more clearly.
Unlocked at level 11.
Description: Reduces explosive damage to 65%, thus ensuring high survivability. This can be equipped as pleased, but it only protects you when it's on. Combined with the Riot Shield, you can survive almost everything head-on.
When the Blast Shield is equipped, it blocks the edges of your screen and your radar as well.
Unlocked at level 19.
Description: You get 1 proximity activated explosive mine. The claymore activates after detecting an enemy and there is a 0.75 second delay before detonation, which you can be increased to 3 seconds with the Scrambler Pro perk.
This is useful for snipers and campers that want to protect their back.
Unlocked at level 31.
Description: You get one C4 explosive. Using this is pretty straight forward: throw the satchel on the ground and blow it up by pressing the same button.
Unlocked at level 43.
Step 4: Special Grenades
Description: You get 2 Flash Grenades. These blind and deafen the enemy for several seconds, depending on how far away they are from the initial blast. If they aren't directly facing the grenade, the flashbang doesn't do much.
If you see a Flash Grenade, try to turn around or get behind cover.
Description: You get 2 Stun Grenades. This causes a mild flash that doesn't effect for very long. The Stun Grenades main purpose is to slow down your target for several seconds, giving you the chance to shoot or even melee them.
If you get stunned and you saw where the grenade came from, try to shoot there, as the enemy will most likely try to rush in.
Description: You only get 1 Smoke Grenade that creates a concealing smoke screen. The Thermal Scope attachment can see through the smoke.

-Pro Ability: This allows you to use your equipment too, for example, frag grenades and throwing knives.
Step 6: Kill Streak Rewards
Modern Warfare 2 expands the killstreak system from Call of Duty 4 and World at War. You have 3 killstreak rewards that you can customize to your liking. You start off with the UAV, Care Package and Predator Missile. As you reach level 10 and beyond, you earn points which you can use to unlock the rest of the killstreaks in any order you choose.
Killstreaks stack up, meaning that you don't lose a UAV after gaining, for example, a Predator Missile. Stacked up killstreaks can't be used as pleased, instead they need to be used in the order you've acquired them.
All killstreak kills (Predator Missiles, Airstrikes, etc.) count towards your next killstreak, except for those that have been acquired from Care Packages. All killstreaks that have been earned during previous lives will not add to your total.
* The Pave Low is currently glitched.
# 3 Kills UAV
Description: This deploys a UAV (unmanned aerial vehicle) that shows enemies on the radar for 30 seconds. Multiple UAVs (from the same team) makes the refresh rate faster.
Unlike in Call of Duty 4, UAVs fly around the map, so they can be shot down. They are rather weak, so it's better to use your primary weapon rather than wasting a valuable missile on them. Players using the Cold-Blooded perk won't show up on the radar.
# 4 Kills Care Package
Description: Airdrops a random killstreak or ammo. If you can't get to the high level killstreaks on your own, use this. Just throw the red signal flare and wait for the helicopter to drop the package. The package can be stolen by anyone, even by your team mates, so be careful!
Care Packages can be seen on the radar by everyone. It's marked green if it's friendly, otherwise red since it belongs to the enemy team. Care Packages, Emergency Airdrops and Tactical Nukes can't be acquired from the package. Below are the drop rates:
14.78% - Ammo
14.78% - UAV
13.04% - Counter-UAV
10.43% - Sentry Gun
10.43% - Predator Missile
9.57% - Precision Airstrike
6.09% - Harrier Strike
6.09% - Attack Helicopter
4.35% - Pave Low
4.35% - Stealth Bomber
2.61% - Chopper Gunner
2.61% - AC-130
0.87% - EMP
# 4 Kills Counter-UAV
Description: Scrambles the enemy radar for a short period of time, even if they don't have a UAV in the air.
Counter-UAVs fly around the map, so they can be shot down just like regular UAVs.
# 5 Kills Sentry Gun
Description: Airdrop a placeable XM312 Sentry Gun. A helicopter will drop the weapon, which you can pick up and place anywhere you want. The Sentry Gun (box) can be stolen by anyone, just like the Care Package, so be sure to pick it up straight away. You can move the Sentry Gun around even after you've deployed it, but it won't fire until it's placed.
The Sentry Gun has a 180 degree turn on its turret and can pitch up and down, but it can't detect players using the Cold-Blooded perk. They are most effective when placed in high places.
Sentry Guns can be temporarily disabled with Flashbangs and Stun Grenades. Normal weapons don't do much damage to it, so use explosives instead. You can instantly destroy them with a melee hit or a Throwing Knife - silly, but true. The turret can over-heat if it's fired for too long, so use that to your advantage. The Sentry Gun will disable itself after 90 seconds.
# 5 Kills Predator Missile
Description: Allows you to remote control a Predator Missile to the ground. Your screen will change to an overhead view and you have approximately 5 seconds to control the missile to your target. You can give the missile a boost to make it go down faster.
Enemies that don't have the Cold-Blooded perk will appear with a red box around them. The Predator Missile has a moderate explosion radius, so you don't need to hit the enemy dead-on. You can also use it to take down enemy helicopters and harriers.
You are vulnerable while controlling the Predator Missile, but if you get killed on the ground, you can still continue your missile attack.
# 6 Kills Precision Airstrike
Description: This is much like the Airstrike from Call of Duty 4, but this time you can control the direction of the Airstrike for more accurate kills.
# 7 Kills Harrier Strike
Description: Airstrike with a hovering harrier. The selected area gets bombed, after that a hovering harrier will guard the area for 45 seconds and tries to kill all nearby enemies. It can also attack enemy helicopters.
This basically combines the Airstrike and Attack Helicopter to one neat package, but the harrier doesn't circle the map, it just stays still. Harriers can be destroyed with one stinger/javelin missile.
Description: Deploys a Attack Helicopter to the map, just like in Call of Duty 4. It will circle around the map and automatically attack enemies for 60 seconds.
Attack Helicopters can be destroyed with one stinger/javelin missile.
# 8 Kills Emergency Airdrop
Description: Calls in a cargo plane that drops 4 Care Packages.
Try to avoid situations where the packages land outside the map. The plane always comes from the opposite direction you're facing (when throwing the red signal flare) and flies in a straight line.
Care Packages, Emergency Airdrops, EMPs and Tactical Nukes can't be acquired from the packages. Below are the drop rates:
12% - Ammo
12% - UAV
16% - Counter-UAV
16% - Sentry Gun
14% - Predator Missile
10% - Precision Airstrike
5% - Harrier Strike
5% - Attack Helicopter
3% - Pave Low
3% - Stealth Bomber
2% - Chopper Gunner
2% - AC-130
# 9 Kills Pave Low
Description: Calls in a heavily armored attack helicopter (Sikorsky MH-53 Pave Low) to patrol the map for 60 seconds. It works just like the Attack Helicopter, but it has twice the armor and two turrets.
The Pave Low also has chaff (1 set) as a countermeasure, so the first locked-on missile won't hit it.
# 9 Kills Stealth Bomber
Description: Calls in a Stealth Bomber (B-2 Spirit) to carpet bomb the selected area. You can also control the direction, just like with the Precision Airstrike.
The airstrike doesn't show on enemy radar.
# 11 Kills Chopper Gunner
Description: Be the gunner of an attack helicopter. Your screen changes to the gunners view and the helicopter will fly around the map. The helicopter flies around for 40 seconds before it leaves, which does not include the time it takes to travel to the map.
The 25mm gun doesn't need to be reloaded, so you can easily kill multiple enemies. Enemies that don't have the Cold-Blooded perk will appear with a red box around them. You are also vulnerable while using this killstreak, but if you get killed on the ground, you can still continue your session.
The helicopter has 1 set of flares, so the first locked-on missile won't hit it.
# 11 Kills AC-130
Description: Be the gunner of an AC-130 Gunship. Your screen changes to the gunners view and the AC-130 will fly around the map. You have 40 seconds to use the 25mm, 45mm and 105mm guns to shoot at enemies, but you can also take down enemy helicopters and harriers.
Enemies that don't have the Cold-Blooded perk will appear with a red box around them. You are vulnerable while controlling the AC-130, but if you get killed on the ground, you can still continue your session.
The AC-130 can only be shot down with missiles, but it has 2 sets of flares as countermeasures, so the first 2 missiles won't hit it.
# 15 Kills EMP
Description: The electromagnetic pulse (EMP) temporarily disables enemy electronics for 60 seconds. It also stops the enemy from calling in killstreaks, and at the same time drops down any helicopters and aircrafts that are in the air.
The EMP also has the following effects on the enemy:
Removes the heads-up display, HUD.
Disables electronic sights.
Red Dot Sight, Holographic Sight, Thermal Scope etc.
Heartbeat Sensors won't work.
Disables Sentry Guns.
# 25 KillsTactical Nuke
Description: Calls in a nuclear strike that kills everyone on the map. It gives you and your team an instant win.
Once activated, nothing can stop it.
Step 7: Deathstreaks
Description: Allows you to steal your killer's class. This can give a sneak-peak at the more advanced weapons, attachments and perks, before you've unlocked them. Note: You still need to unlock the everything on your own.
Unlocked at level 4.
# 3 Deaths Painkiller
Description: Works almost like the Juggernaut perk from Call of Duty 4. After you respawn, this gives you twice the amount health for 10 seconds. This can prevent most one-hit kills.
Unlocked at level 6.
# 4 Deaths Martyrdom
Description: Drop a live grenade just after dying. Like in Call of Duty 4, this is useful in rooms where it's difficult for the enemy to run away from the explosion.
After you kill someone and you hear a grenade drop, RUN!
Unlocked at level 27.
# 4 Deaths Final Stand
Description: Just like the Last Stand perk, but with more improvements. Basically this allows you to survive a normal death. You can crawl around on the ground and use your primary weapon and equipment.
You have a little more health than in Last Stand and if you survive long enough, you can get back up and continue to fight normally. This does not reset your ongoing killstreak.
Unlocked at level 39.
