How do you play two players in Grand Theft Auto 4?

U can't play GTA IV with 2 players i mean Split - Screen u can play online by registering yourself and then use the phone with the arrow up button on your keyboard then select menu then select multiplayer. If u have a Illegal GTA IV dont do multiplayer then u can be detected with playing multiplayer on a illegal GTA IV. Only use it at your own risk. i am not responsible if u do that. I hope u could use this information i just had nothing to do at the moment. Greetz Indochan14
