Could you explain them in a simple way?

[RedKit]

I need someone to help me understand these statements which are from a game named Max Payne 3. I'm trying to translate them into my native language, so people in my country can play it.
"The force fenced in the felonious friends for a foul feeding frenzy." (don't understand that at all)
"There are updates going live with a CS hashtag, calling for an attack."(what is the exact meaning of hashtag?)
and some phrases like "get coal" and " have one's nest egg".
I know it is kinda hard to explain all of them, esp in different words, but i will be grateful if you at least make them easy to understand for me. Thanks in advance.
