My achievement was actually pretty exciting.
I was playing online in Street Fighter IV on my 3DS. I picked Fei Long, to change characters a bit, and got paired with a Sakura player. So, the fight started, and I won the first round.
My opponent won the second. The final round began, and I was getting my ass kicked. I barely managed to land a few hits, and my healthbar was literally non-existent (even if I blocked the weakest attack ever, I would steel die).
My rival decided to finish me off with a kick, but I, reluctant to lose, used the ultra combo of 1 inch punch, which is a counter. I succesfully hit my opponent, but the duel was not over yet. I used a few chicken wings to go over Sakura's hadoukens, some kicks here and there and the rest is history!
I epically won, and with a Bruce Lee character to add to the awesomeness factor. Reminded me of that ocasion in which Daigo Umehara parried the super combo of Gary Wong in that tournament and won.
That is, up to this point, the most badass thing I've done in any game ever.
