"The Core is way way harder than the Undead Core on a 3HP run IMO, mainly because when you get to the Undead Core you have the Booster and the Spur and you don't have you dodge projectiles with the horribly slow underwater physics. I battled the Core so many times that I actually learned how to influence his pattern so he would do the same thing every time, and then I memorized his movements."
Jeez o_o...I didn't know you could influence his pattern. The core was a hard boss to beat for me but it didn't take me as long as the undead core really..I guess I got lucky.
"I gave up on Hell 2, because I could do the rest of the level without much trouble but 2 was just extremely annoying, and I only ever got past it once when practicing each room with debug saves."
If you're talking about the second room in Hell with the falling blocks and stuff, yeah it is incredibly annoying and it's really hard to get by without some luck so that the blocks don't fall in bad places..I swear there were times where the blocks were literally blocking my path or out to get me with vengence.
"Also, how did you do the eye trick on the final form of Ballos? I always thought it was impossible on a 3HP run, because after I get hurt by the 2 damage spikes and fly up onto his eye I just get killed by the mini-eyes when he becomes damageable. You seemed to be using a turbo controller, but does that really kill him fast enough to avoid damage or is there something I'm missing?"
I wasn't using a turbo controller, just my regular PS2 controller that I have, I was mashing it like no tomorrow though cause after all that trouble to even get to there I was wanting him dead as fast as humanly possible. About dying on his eye though...I dunno, perhaps you were too far out of his eye and one of the floating eyes hit you or maybe the invinciblity from getting hit wore off too soon or something.
