Beating Bosses on Hard with Sting (VITA)

[Jim_bag]

I just got the platinum on this and if you use Sting (the martial arts guy) on your Hard play-through you can constantly spam the attack button (square or triangle) and he becomes invincible as long as you're attacking. On the VITA, with the hard buttons, I recommend alternating back and forth between square and triangle to keep attacking during the boss battles.  My thumb was starting to cramp up. Good luck!
