I'm new to the use of mods and i want to know how would i use a mod on the steam version of cod mw2 because i see other people do it and i have this admin type mod that allowed you to kick players and such and i would like to know how i install it and use it, i found some info about alteriwnet but that's no good because i use the legit steam version of the game

sorry if this has been posted before just want some help about this

-Thanks
