After you have gained all the valuable details, head on over to Metro where a map, squad, and pre-assault tabs lead you through to active combat. This is a map of Los Angeles with the divisions broken down, and all reported incidents appear on the map as colored dots. By selecting a blue dot on the map, you get another screen representing the crime incident. Included in the briefing is a description of the hostages, and the tactical advantages where you select your point of entry, and tactical mode of play. You can choose stealth mode which is more cautious or the dynamic mode which is a more aggressive approach.
Weapons come in primary and secondary classes.
Your primary weapons include the shotgun, machine-gun, etc. Ammunition is available for all weapons. You also have a choice of tactical aids such as light sticks, lockpicks, handcuffs, CS gas, etc. The F-Keys are all preset and cannot be reconfigured. I usually don't like it when someone tells me I can't change something.
