I remember the SWAT Series and Rainbow 6.
Even though they were more like Tactical Shooters.
The market is flooded with military shooters, so why not making a AAA Police Shooter?
Different environments, different gadgets, different weapons.
Obviously you would have different RoE than in military shooters, but still...
My focus lies on the MP btw,
Only can hope for R6 Patriots. Although I think it wilö suck balls. ( its from Ubisoft and the development is a mess as it seems )
