“There are a number of ships on Genesis that you could use to leave.”
	“I thought you said there weren’t any?” I asked as a new wave of the robotic Forerunner infantry attacked us. They were bipeds that stood about three meters tall, made out of floating metal bits that seemed to be animated by a glowing energy, and they had this unnerving way of teleporting short distances as they fought with you, leaving luminous streaks in their wakes. Exuberant Witness called them armigers , but to me they were just a colossal and chronic pain.
	...
	“When the Guardians came here to Genesis, they didn’t always come alone,” Exuberant Witness explained as we trotted after it, taking down any Forerunner soldiers who reared their shiny heads.
	...
	“A number of these stowaways came from human-populated planets,” the monitor said. It floated higher then to give us a clear field of fire at a fresh detachment of Forerunner soldiers charging at us from the flank.
	...
	We battled our way through another wave of Forerunner armigers, concentrating on moving forward rather than fighting.
	...
	I shot down a Forerunner soldier that appeared in front of me and then stomped my boot through its silvery face without breaking stride.
	...
	“Anybody else worried that maybe a Forerunner AI just left us here to fight hundreds of Forerunner soldiers?” asked Fred as another wave came from the direction opposite the last one.
	...
	As we neared the dropship, I saw bodies sprawled everywhere. Most of them were the remains of Forerunner soldiers, but I spotted a helmet from a UNSC marine, too.
	“Must have had her cap knocked off before they got her,” Vale said.
	I knew what she meant. The Forerunner weapons didn’t just kill you. They obliterated you. It was like you simply evaporated into glowing energy crystals that faded into nothing faster than your last breath. They were absurdly powerful machines that the brains at ONI were still trying to figure out.
	There wasn’t anyone alive in the Pelican. Not even a remnant of them left behind.
	As we got closer, the Forerunner soldiers seemed to sense that we’d found a means of escape and that their time to stop us from using it was running out. Energy bolts from their hard-light weapons spattered against our armors’ shields from all angles, and I realized they’d managed to completely surround us.
