Any hint?

могу я попросить вернуть мне средства за эту игру или заменить её на другую

I will be brief, how to get these two achievements? Буду краток, как получить эти два достижения?

Where is it?

I got all the achievements but not this one, you have to get it in HARD WORK level. From its title and icon I thought that I just have to kill all Banshees, but it didn't work.
