JUMP FORCE

This is super simple. Preferably do this ASAP seeing as the servers close in August. There are multiple achievements tied to playing matches with online players that this is related to as well.

Make sure you have completed the tutorial as online play will not be opened up to you until you do.

Select your Avatar and choose to play online.

Grab a friend with a copy of the game or make a friend in the pregame lobby. Go over to online battles and select the "Friendly Match" option. Make sure the "Friend Invite" option is turned on. Click confirm.

From here you will select your team. Seeing as you are going to be working with somebody the team shouldn't matter too much. I would however recommend not using your Avatar if you are looking unlock all of the titles in this game as all of the playable characters have titles associated with playing with them.

After you select your team, you select whatever map tickles your fancy. After that your Xbox will pull up your Xbox LIVE friend's list to choose your opponent. Find your friend and send him the invite. From here just figure out who wants to go for the win and TA-DA! You and your friend should have the win in no time. If your friend goes first just make sure you rematch him and then you can take the following win!

If you're looking to get the remaining online achievements, be aware that you only need to win for this achievement and the ranked achievement and all of the other achievements are related to games played, not games won.

Happy fighting!
