Hello There, i'm new to this forum but ill be making a introduction real soon don't worry i would just like to ask a question and would like your feedback. I have Mw2 on steam and would like to download the alterIWnet mw2 because its got dedicated servers which have promod and free maps and would like to generally start hacking on the game doing for instance global thermonuclear war , promod and other things but im not to sure what im really doing. If i download the alterIWnet one when i already have the steam one would both mw2s catch up with each other meaning like something would go wrong with my original one ? please can you get back to me ASAP and thanks for your co-operation and one more thing if i wanted to start doing a little hacking on mw2 what would i need ? and i mean the alteriwnet one .
