You assume the role of team leader in the tactical response team of a major city police force. Your work is to plan and carry out tactical entry in barricade and hostage situations with least possible loss of life the desired outcome.
I'm playing around with explosives. Doors can now have explosive booby traps.
If there are any on them when you examine them you are notified and then you can disarm them.
Also now the fire alarms get triggered by smoke. You can turn that off in the options if it's annoying.
