Summit

Summit is a snowy map with a number of defensible positions. One of the most popular and effective positions is the rooftop with the flag on it. A simple yet challenging parkour is required to gain access to the roof, making it very defendable, even in small numbers. People who are bad at parkour should not attempt this, as many have perished from the zombies while trying to get to the roof. When the rooftop is overrun, it is a tipping point in the game, effectively winning the game for the zombies. The defenders, if not killed, should head to the nearest exit and start running for their lives.
