PS3 has wireless internet built into the console. Just read your PS3 manual and find out how to get the internet connection set up.

Once you're in the game menu. Go to "game modes," then, "online play," then, it would ask you to register really quick which asks a yes or no question then BAM! online play! Enjoy the rest of the world in fight night...

This feature is free on the PS3 but if you have the Xbox360 it costs money...Not trying to start a console war, but the monthly fees was a reason I chose the PS3 over the 360
