			This is an exploit for the GameSpy secure query in
			the Unreal Engine.

			This exploit only requires one UDP packet, which can
			be both spoofed and sent to a broadcast address.
			Usually, the GameSpy query server listens on port 7787,
			but you can manually specify the port as well.

			The RunServer.sh script will automatically restart the
			server upon a crash, giving us the ability to
			bruteforce the service and exploit it multiple
			times.
