BlazBlue: Continuum Shift

To Perform a 'Barrier Crush' you need to attack a defending Opponent until they run out of Guard Primers. Every Character has a set of Primers in between both Player's Health Bars; they are represented as Rectangle Shaped Icons just below the Timer.

Blocking Attacks without using your Barrier will gradually destroy your Primers; once you run out, you will suffer a 'Barrier Crush'. Being Barrier Crushed will reduce you immobilised for a few seconds, and as such gives your Opponent an Advantage.

For this Achievement, we need to be the one to cause our Opponent to Crush. Getting this Achievement against the AI is very difficult and more or less luck based, so we have two options; either find a Partner to boost this Online, or plug in a Second Controller and get this with yourself.

Regardless of what conditions you are using to unlock this, make Player 1 Iron Tager and Player 2 Carl Clover. Have Carl walk backwards into the Corner so that he is constantly blocking; with Tager, walk up to him and continuously input 'Forward + B' until you break your Opponents Guard (Shouldn't take too long), unlocking the Achievement.
