During one of the special operations in Syria a Spetsnaz Soldier discovers a hidden bunker with a lab within it. There he finds a set of time travel machines, using which are used by hired assassins to travel to the past to change the history in favor of the U.S. Traveling back into the time the player will be able to visit the most historical places on earth and be ready for engagements any time. The main difference from most of the shooters is that instead of getting an upgrade of the equipment the player would downgrade as he/she progresses through the game. The game will start as a standard action fps in close future setting an move back in time up until stone age, where the game would shape into more of a action survival. The player would have to come up with various approaches and new weapons to eliminate the assassins and save the history.
