Nope 4 Spartan II, and 3 spartan III are still alive. Greg, Kelly, Vincent, and John spartan 117 are still alive. Kelly, Greg, Linda, and Vincent are stuck in a forerunner structure that was created in order to preserve life once the flood had been released. I shed some tears when Linda, and kyle died they were so close to escaping from the covenant but they had to hold them off in order for the other spartans to survive. It was pretty sad when they got blasted by like 20 hunters and like 100 elites.=(
