Hacking XP and Challenges!

Hi, heres my tutorial on hacking Modern Warfare 2.

First Download CheatEngine 5.5 : Cheat Engine

XP Hack:
1). Start Modern Warfare 2 Multiplayer.
2). Minimize(ALT+TAB) MW2 and start Cheat Engine.
3). On Cheat Engine click the computer icon (left upper corner).
4). In the new box, which popped up, choose iw4mp.exe
and click on "Open".
5). Click the button called "Add address manually" then type in 01AD3E9C (this address might change when they update MW2) and click "Ok".
7). Change the value by clicking it with the right mouse>change record>value
8). Now open up MW2, and in the menu, click on "Barracks".
Now look at your current XP. If you just want to go up 1 level add the amount of xp needed like this: Let's say you have got 165000 xp, and need 4500 xp to level up, add 4499 xp to the value youve got in CheatEngine (So 4500-1) and click on ok.
9). Go in a game and kill a guy, and if you've done it all right, you should have gained your new rank.
10). To go to level 70 instantly you can change your value to: 2434699 (thats the xp needed for level 70 -1xp)
And again kill one guy.

THATS ALL Enjoy your level 70 + Prestige10 (if you do this 10x ofcourse)


And now for the Challenges:

Do step 1-4 on the xp-tutorial.
5). Open MW2.
6). Click Barracks>Challenges.
7). Find the weapon challenge or challenge you want to do.
For Instance: The assault rifle FAMAS:
8). Look how far you are in one of the challenges for instance: Expert(for cammo's)
Let's say I got 87/150 headshots.
9). Open Cheat Engine. Search for your that first value (Exact Value, 4 Byte), in this case 87.
10). There will come alot address up, and you wont be able to find the right one yet.
11). So go in a game, and shoot someone a headshot with the FAMAS in my case!
And lets let's say I've got 89/150 now.
12). Go back to Cheat Engine, search your value, in this case 89.
13). And you will have only a few or one addresses left.
14). Select the addresses and click on the Red Arrow pointing Down.
15). Now you select all the addresses in the box down and right click>change record>value.
16). In my case i now change the value to 149 (150-1).
17). Now go in a game make one headshot and you will have finished the challange!

Well i hope you all know how to Hack MW2 now,
Good Luck and HAVE FUN!
