Inspired by SWAT 4 and gritty police TV shows, Police Stories is a fresh take on top-down shooters with an emphasis on tactics that forces you to make split second decisions. Neutralize criminals, rescue civilians and defuse bombs in Single Player mode or Online Co-op. And remember - shooting first is not an option!

Unforgiving and tense, each mission tells a story of two police operatives - John Rimes and Rick Jones, filled with infiltrating gang hideouts, rescuing hostages, making arrests and other life-threatening situations.
