Marvel vs. Capcom 3: Fate of Two Worlds

Simply play an arcade match and be careful not to touch either of the bumpers at all, or the left trigger if you have more than one hyper combo. Also, be sure not to let your main character die during the match. Set the difficulty to very easy and the time limit to 30 if you must to make the battle go by faster. You only must complete one match this way, not the whole arcade mode.

In either an Arcade or LIVE match you'll need to win a match without calling your support partners or switching out.

To call in your support character you'll need to press the LB or RB button. To switch out to a different character you'll need to press and hold LB or RB until the switch is done. IGNORE THE BUMPERS COMPLETELY!

If you just rely on yourself and play well you'll be able to beat your opponent and earn 10G!

Ok this is how you get the "A Hero Stands Alone" achievement.
1. Go to arcade mode and pick 3 characters that dont suck.
2. Go to settings and put the difficulty to "Very easy"
3. When you start the match DO NOT PRESS ANY OF THE BUMPERS.
4.Win the match
5.Achievement unlock
PS. This achievement is worth 10 Gamerscore, 12 TA Points. Enjoy :]
