In 2559 the U.N.S.C and the Banished Brutes are at war on the Planet X-472. While this happens, the A.I (Skynet) sends a T-800 Terminator to the future to continue Skynet in the 26th century. It’s up to an O.D.S.T, a damaged spartan, and a soldier from Judgment day to stop the advanced T-800 (Maximus) before he terminates the earth.
