Thanks to all that enjoyed this hack.
I want to clear some points.
1) I didn't created this hack (It's from *************, all credits goes to KN4CK3R), I simply posted this here.
2) I suggest you to use the second hack that i posted in this thread since it's the most updated version
3) I didn't tested this hack, I'm using the 175 version of the same hack and it works like a charm
4) How to inject the dll:
Find the dll (the 2nd hack got it)
Start MW2 (don't press anything in game, just leave it like it started)
In Winject process list put iw4mp.exe
Go back in game and enjoy it
