Czech game developer Bohemia Interactive Studios' Spiritual Successor to their successful and legendary Operation Flashpoint series. Unlike the original, these installments take place in Present Day and Next Sunday AD time frames, not the Cold War. The basic premise and game design philosophy of making a well-researched, true-to-life and unrelentingly realistic simulation of everyday military life is still there though. As is the practice of using various fairly funny (and Reference Overdosed) Ruritanias as the setting for the games' campaigns and missions.
