So I was thinking of making a game where you can be a rob a place (stealth or loud like entry point or you can be a cop where you can stop the robbery before it happens or while its happening.
The good guys
This team is about stopping the robbery and the robbers. It can be cops, SWAT, spy, or military.
The difficulty will range throughout the story, also you can go stealth or loud. There will be warnings when the public or the robbers notice you are there. Once the public knows that there is a armed robber, the public will escape to safety but if the robbers know you are there they will start the robbery loud.
The bad guys
This team is about robbing different places and avoiding the police. There will be warnings when the public or if you are doing suspicious behavior. Once the public knows that you are in the building the public will escape and try to call the police. If the place you are robbing is a building with guards, the guards will try to shoot you or lock the doors and set traps then they will escape to safety.
Conclusion
You can be a cop or robber. This game is similar to entry point, and jailbreak.
