WOW!!! We were originally the bad guys! The Red Race was truly malfunctional after all:

"Years passed and one race of machines on the planet Eden 4 suffered severe damage due to electrical storms. Most of the controller’s memory was damaged but the controller continued to function. The damaged machines continued to build until they exhausted all of the resources on Eden 4. The planet surface is now littered with steel and the controller decides that to further colonize, it must seed another planet. The planet they reach already is home to another race of machines, and a fierce battle for the planet’s resources begins."
