So with all the games out there, comes a lot of different mulitplayer online games. Who has the best? There's a lot to choose from, but I am going to just stick to talking about Call Of Duty, Halo, and Gears Of War. I have played more mulitplayer games then these three, but they are the main ones I play. I have played some Assassin Creed, Army Of Two, Resistance, Left 4 Dead, Mortal Kombat, BioShock 2, Dead Space 2, Madden, and Grand Thief Auto 4. I am sure I have tried other games also, but those are the ones off the top of my head. Now Madden is Madden, and same goes for Mortal Kombat. You are just playing someone else in football. And as for Mortal Kombat, or say a Street Fighter game, you are going online to fight other player. So there just your basic online multiplayers. So you got your two types of multiplayers in my option, run and gun and duck and cover.
