REDD War

In the year 2029, humanity lives alongside a race of violent alien creatures known as the REDD. The species mainly live together in peace, but for 12 hours a year, 5 randomly selected cities on the planet turn into a war zone between REDD and humans in an event known as a "REDD War". This year, Casey Conrad's town of Springfield has been chosen among the list of cities. Will he and his father survive the night, or will they fall victim to this annual time of bloodshed?
