First when you buy a copy of MK you will recieve a kombat code that you will need to enter so you can play online. Now in MK online there is the standered 1v1 matches. But the developers decided to add 2 new features to the series. First there is tag team mode which is 2v2 type game mode. You can play this local or online from 2-4 players. But I saved best for last. This component is called king of the hill. What you do is its 1v1 and obviously you fight your opponent. But the other players watch in the movie theater and show off there mk avatar. When the fight is over everyone rates the match from 0-10. When the opponent loses the next person in line faces the winner and goes on and on and on. The lobby is also great because you can start talking with other people in the world there in with a headset or not. I recomend playing the AI first before playing online. gamertag: fremis1234 (ps3) fremis (xbox360). rating 9.5
