This achievement is unlockable in all game modes except private matches.
To unlock this achievement you must recover from a "stun state" from a strike.(including punches, knees, elbows, kicks, etc.)
A stun state is when your FOV changes, and your character begins to wobble The best way I have found to survive this is to either create distance from your opponents and allow it to wear off or, strike back and hopefully put your opponent in a stun state or even knock them out. Good Luck!
