I'm at the section where you have to kill Elizabeths mother in the graveyard, but I just can't do it. I can't get enough bullets into her before I eventually die. Anyone got any tips? I'm playing on hard.

The first time or the second?

I zapped her a few times and shot at her from distance, while using the bronco vigor to keep her troops occupied. Worked in both encounters.

Best technique is to trap her with the crows and keep shooting her till she dies.

Thats my technique

Well been stuck on this fight for 2 hours now and just cant do it on hard, must be because i didn't focus on choosing health or shield upgrades. Never-mind gave it one more go, i found that using that charge vigor then head shotting herwith the hand-cannon was effective, just spammed that. Would not be so bad if i could just restart from the battle instead of at the locked door, thus having to regather what i gathered by backtracking.
