Today I need to talk to you about November 17, 2552 and the Battle of Kenya. The official story is that the Covenant glassed the area in a sneak attack, killing thousands before we could stop them.
Trust is... we let them do it.
The glassing was a last ditch attempt to stop an alien infection called the Flood. Had the plan failed... the Earth would have fallen in hours.
Officially the Flood's all gone. Kaput. But if humanity encounters the Flood again, Spartans are our first line of defense.
You need to know what you could be up against, and you need to train to deal with it. I've loaded up a Forerunner themed test location and set it to be infested by Flood. Good luck, Spartan.
