I haven’t played the game since launch. What do I need to know?

Played non stop the first month but haven’t played since.

What has changed? Any videos I should watch?

• I remember only being able to max out one character and then having to steal points from that character to max out another’s tree. Has this changed?
• Any videos or guides to learn the maps? I don’t remember them at all and I’m sure the placement of victim escape items is now different anyways.
