Tekken Tag Tournament 2

To earn this achievement that's called "True Friendship", you must have pulled off at least three Tag Crashes. I wasn't sure how to pull it off, but then I saw a video guide that showed me exactly what to do. This is how I went about getting this achievement.

Start up the game and go to Practice mode. Chose any two characters you wish to play as and select any one or two opponents. Select any stage and once the fight begins, load up the menu by pressing start.

Once you are in the menu, you need to go Advanced Settings and choose that option. Next, select Rage, which is the third option in the Advanced Settings menu and choose that option. Once you did that, turn the rage on for both you and your partner. After you did that, return to the menu and go to Mode Select. On the Mode Select menu, choose Vs CPU Training, followed by Difficulty Level. On that menu, crank up the difficulty to Ultra Hard. Then exit out of the menu and return to the gameplay.

If you have these options right, both you and your partner should have flashing red bars on the top of your screen, plus the enemy AI should be attacking you aggressively from this point on (until you turned off the option, of course!) Each time you land on the ground from one of their strikes, immediately tap RB+Y. Your partner should jump down on your opponent, which should count towards your Tag Crash achievement. Then have the opponent get you on the ground two more times so that you can do a Tag Crash two more times in return. Complete all three successfully and you should earn the achievement in no time.

To see exactly what I am talking about, please refer to the video guide I have attached with my solution below. All credit for creating and publishing this video goes to SirJrGaming. Following this gamer's guide enabled me to earn the achievement no less than a minute.

Have fun and good luck!

Easiest way to do this is in practice

Select tag match
Pause and go to 'Advance settings'
Select 'Rage' and turn on for both main and partner
Then in pause menu select 'Mode Select' then 'VS cpu training'
Now back to the game, the cpu will attack you, when you are on the ground hit + and your partner will tag in and come in with an attack
Do this 3 times and CHEEVO!!!

Tag Crashes are used when your main character is beating beaten on in a tag match and you press the tag button + Y when the partner is flashing red in rage mode and you are on the ground. If you do this correctly your rage mode character will drop in with an attack and swap out.

This is best done with two controllers, if you want to make it land be sure the other controller isn't idle or they will block. You don't have to win the match for these to count or anything of that nature.
