Tekken Tag Tournament 2

To earn this achievement, "Tug at My Iron Heart Strings", you'll need to win a player match in Online mode.

Thanks to the help of a friend, I earned this achievement by defeating him in three rounds. After I defeated him, the achievement unlocked. So you can either take your chances against a random, human opponent or you can ask for a buddy to aid you in this achievement by having him or her lose to you. Go with the latter and you'll get the achievement in no time!

Have fun and good luck!

You could arrange to do this with a friend so they can let you win or you can do it legitimately. Go on quick match, when refining your search set the ranks to "2+ only", this will ensure that your opponent will be no more than 2 ranks higher, chances are you will find an opponent who has roughly the same amount of experience as you. It doesn't matter who you use for this but I personally used Forest Law and Paul because Law has his really fast moves and Paul has his really strong strikes, hopefully you'll win and get the achievement. You can repeat this two more times to get the "Iron Heartache" Achievement for playing 3 online matches, the matches do not need to be won for that achievement.

Good Luck xP
