1. Killed a big daddy, only there was no little sister to be found. That's bullshit. They should be right there beside them. I looked everywhere and couldn't find her. So I basically wasted a bunch of ammo and time being killed over and over for no payoff whatsoever.
2. When you "die," if you're pulling the trigger, the first thing you do in the revitalization (or whatever) chamber is fire whatever weapon you were using, no matter if you let go of the trigger or not. That's bullshit - you pretty much always waste a shot upon rebirth.
I think Gerstmann might be right about this one. I love the design, music, atmosphere and style, but it's not a perfect game by any means. Wasting that time and ammo killing that Big Daddy and no little sister afterwards nearly made me want to quit playing.
