HOLY Chapter 9 boss was INTENSE. It's like I just had it figured it out, been fighting for almost 20 mins, got him down to 1/4 health, then the Doom counter appears over your head...
Switched from a conservative strategy to a balls to the wall strategy and beat him with about 150 left on my counter (on my first try, too

) Haven't had my heart in my throat like that (while playing a game) for a long time.
