In Darkest of Days, the action begins with the player being ripped from his period in time by a mysterious organization moments before his grisly death. In order to ensure the future of mankind, he is then tasked with the mission to travel back and forth through time – to famous, turning-point battle campaigns in world history – acting as the organization’s agent in a larger, seemingly otherworldly, battle between good and evil.

Using a combination of both futuristic and historical weapons, players will be immersed in a world where in one instant they will be fighting against the Huns in World War I and the next find themselves battling at Antietam in the U.S. Civil War. A variety of combat missions, such as stealth, artillery assaults, and sniper attacks will keep players on their toes through dozens of levels spread out over five historical time periods – all while discovering the secrets of the mysterious organization for which they have been working. Fighting on one side of the action, then sometimes coming back to fix mistakes on the opposing side gives the player a chance to experience conflicts from both sides.
