I forgot to add, the new fight with Radeka is very properly annoying - in a good way that makes you really hate her guts and feel very pleased to beat her and those damn puking bugs and zombies.
Ai is very good there too. I though i was smart to cast pain shackles on her, but she responded by casting pain shackles back onto me. That was a good "what the hell do i do now?" moment.
