Rayhoven Base was and probably still is an ISA military base, which played a crucial part in the ultimate defeat of the Helghast forces on Vekta.

Killzone: Liberation Edit

Rayhoven Base is located on Southern Vekta near Rayhoven City, it was home to scientist Evelyn Batton, Minister of Defense Heff Milcher and General Dwight Stratson during the Helghast invasion of Vekta. The three of them convened to discuss the use of the Red Dust nuke on the Helghast forces. Later, the base would be stormed by Helghast forces, but Jan Templar would come to the three's rescue, although Heff Milcher would die.
