Ok so everyone knows about the program rPE.exe, many people use it to hack the game Mission Against Terror

Well I tried to manipulate mission mode and co-op mode (solo)
but I came to no avail
Any my account was banned
I tried to send the packets for clearing levels, the ammount of mission badge thingys lol, and cpu kills
So maby you guys could come up with away to or tell me that its impossible because I am not sure if this game is hackable through packet sending/injecting
