Admittedly, I DID have the hadouken upgrade which allows you to one-shot-kill the dog and Sigma's first form. That allowed me to fight his final form with full health and all four subtanks full. I needed every bit of it too. By the time I dealt the final blow, all 4 were empty and my health bar...
Still working on Twilight Princess. Taking a bit of a break though. Finally beat Mega Man X last night!! I bought it new about 20 years ago and spent all of that time either rage quitting or losing my codes!!
I bought LoZ: Phantom Hourglass without knowing the gameplay is vastly different but I'm still going to at least try to finish it now that I've started.
