Notes:

Numpad 1: Freeze Timed Assignment Timer - while in the game, when an assignment is created on the map by dispatch, toggle this on to freeze the assignment timers.

Numpad 2: Set 999999999 Money - while at the dispatch map and you can see your money, toggle this on, and when you assign a unit to a call, the money will increase.

Numpad 3: Unlimited Workday Weapons - on the screen where you assign weapons to the force for the workday, assign at least one weapon, then toggle this on, then assign another and you have plenty.

Numpad 4: Assignments Require 0 Professionalism - click on a dispatch assignment, then toggle this on, then leave the assignment, then click on it again and you will see that the assignment requires 0 professionalism.

Numpad 5: Police Will Take All Assignments - assign a unit to a dispatch, and then if you click SEND and they have a reason they won't go, toggle this on, then try again.  Even if they complain again, they will likely go on the assignment.

Numpad 6: Unlimited Level Up Points - for this to work, you need to have had an officer that got a point during the current play session, then toggle this on.  The next officer that you have points with and the rest of the play session duration, you will have unlimited points to assign that officer.

Numpad 7: 200 End of Mission Tabs - you need to complete a workday and spend some tabs.  Toggle this on.  THEN, at the end of the NEXT workday and each workday of the current session, you will have 200 tabs to spend.

Numpad 8: Unlimited Workday Energy - once a unit has been sent to an assignment, the energy of the unit decreases.  If you see this, toggle this on, and then the unit will reset when the next energy is to be spent.

Numpad 9: Police Do Not Tire - during a workday, the units tire and may not be able to work the next day.  Toggle this on at the end of the workday, then when the next workday ends you will see that the units are not tired for the following workday.

F1: Unlimited Combat Moves and Actions - once you are in combat and have selected a unit to move, toggle this on and then that unit can move and perform unlimited actions.

F2: Expose Enemy Locations In Combat - once you have entered the combat and can move units, toggle this on.  Once you move a unit to a point where the game calculates what can be seen, it will likely expose all the AI units.

F3: All Police Combat Skills are Enabled - you need to reach a point in combat where you can engage a skill (for instance when you are near an enemy and you can cuff or shoot them, etc.)  Open the skill panel, then close it, then toggle this on, then re-open it and you will see all the skills are highlighted to be used. Some skills may still fail if the unit is not trained in that skill.  To help in that situation, use the option below.

F4: Cop Is Able To Perform All Skills  - you need to reach a point in combat where you can engage a skill (for instance when you are near an enemy and you can cuff or shoot them, etc.)  Open the skill panel, then close it, then toggle this on, then re-open it. Then certain things (like defusing bomb and etc.) are available to be done by that unit in many cases.

F5: Cops Are Invisible In Combat - Once you have entered a mission where you can move cops around, toggle this on and the enemies cannot see your units.  To ensureit has  taken hold, you might also click RETRY MISSION right at the start while this is active and you will have total invisibility to the enemies.

F6: Unlimited Combat Weapon Ammo - once you have entered the combat and can move units, toggle this on.  When you fire weapons the ammo remains locked.  If the ammo displays 0, you still have plenty.  You can toggle off and select another unit and then select back to see it is changed.

Numpad 0: Easy Complete Crime Sequence - for open investigations where you have sequence photos, even if you only have one clue, drop the photo onto the timeline sequence and then activate the trainer, then redrop the photo onto the timeline and you will be able to indict the criminal and close the case.
