It was about a year after CE had come out, and I went over to a friend's house to spend the night. He told me about this cool new co-op game called Halo, so we decided to play it. Keep in mind, I had never played an FPS before, and the scariest thing I had ever seen was the Pink Elephant scene in Dumbo. So what does he do? He puts it on Legendary and we play through the final level. Actually, let me rephrase that. He gave me a pistol and a shotgun and told me to sit in a corner and shoot anything that moves while HE went through the level. I had nightmares from the Flood for a straight week, then couldn't wait to play it again next weekend.
