It’s 1965 - the height of the Cold War. Spymaster Philby has dropped a list of all double agents in the middle of Checkpoint Charlie, on the Berlin Wall. Both Soviets and Allies know how critical the data is to the war effort and both have mobilized crack strike teams to retrieve the data and pass it to friendly agents deep within enemy territory.
The Allies and the Soviets start from bases on either side of the Berlin Wall. The objective is to storm the wall and capture the flag from the centre of Checkpoint Charlie. Once the flag has been captured it must be taken to the enemy’s base on the far side of the wall in order to win the game.
