For those of you who haven't beat the game yet STOP READING THIS. I was confused. So Master Chief fired the new Halo to kill Gravemind. Got it. But wouldn't that kill all life in the galaxy, or did I miss some really important detail because it sure looked like everyone was alive at the end. Also, if you think it was gay because it looked like Master Chief died at the end then be sure to watch after the credits. It explains how the Arbiter and Master Chief got separated after Halo detonated. Master Chief survived. Part of the ship broke off when they jumped into slipspace. Cortana sent out a distress beacon but said it might be years before anyone come for them. Master Chief climbs into the Cryo Chamber to wait; however, if you beat the game on Legendary you will see their part of the ship crashing into a planet. I liked it. Plus the last level was fun with the final Warthog (Puma) ride like in the first game.
