Marvel vs. Capcom 3: Fate of Two Worlds

The way to get this achievement is to just keep holding back on the left thumb stick and just let the computer whoop on you. Or you and a friend can go into a private match and just whoop on each other until you both get the achievement. If you do it against the computer put it on very easy or easy and set the time to infinite. Hope this helps.

For this achievement you'll need to block 100 times across your playing of this game. In order to block you need to move away from your opponent when they go in for an attack.

Either do a private match with a buddy or play through the game normally, with blocking in mind and you'll pop 20G in no time!
