In Payday: The Heist, how do you change which upgrade tree you're on?
Three friends and me have started playing Payday - The Heist. Unfortunately we have quite a hard time in "understanding" some of the basic mechanics in the game. So my first question is :
Is there any new player guide to this game? Because if so, I have a hard time finding one
If not, then maybe you can answer some of these questions:
What exactly do I gain by destroying video cameras?
Are hostages any more than just Trade objects for my teammates in custody?
Are there different classes? If so , how do I change? If I press Tab and switch with 1,2 or 3 nothing actually happens.
Is there any system to the Police Assaults? -> How do they get triggered? After passing a specific checkpoint or after a specific time? If so, when is the timer resetted?
Do the assaults end due to a timer or a bodycount?
Edit:
I just want to make question 4 about the police assaults a bit more specific:
How do they get triggerted? This means - when will a police assault start? Does this depend on some kind of timer ( for example: a police assault will start every 5 minutes ) or does it depend on mewalking over a specific location (e.g. I pass a crossroad , which means now there will be a police assault incoming)?
