The tone of this game is somber. The primary goal in most game modes is to cause the greatest loss of life in your opponents as possible. There should be more freedom in unit selection, and a more detailed scoring system that rewards strategy.

More realistic and slower paced than some other shooters. The guns also tend to be less accurate than your normal video game for realism, and shooting while you run is nearly impossible. Still, a reasonably fun multi-player FPS.
