The 2009 first-person shooter originally for the PC and XBox 360, Darkest of Days , has been brought to the Mac by Virtual Programming. The game revolves around a time-travelling soldier who has to revisit some of history's greatest events -- from Pompeii in 79 AD to a World War II prisoner of war camp -- to save key individuals from being killed by rival time-travellers hoping to alter the course of world events.

Gamers portray Alexander Morris, a soldier plucked from General Custer's army during the battle of Little Big Horn and charged with protecting history by reliving key battles and events from the last 200 years and beyond to save humanity. Players have the opportunity to use and experience both the weapons of the time periods they visit, as well the possibility of using (relatively) futuristic weapons out of historical context, like a machine gun to help eliminate an ancient Roman garrison.
