[b][i]CREDIT GIES TO JOSIAHSPARTAN[/i][/b] [quote]So I don't think the trailers were meant to be taken literally. I also don't think there will really be two endings. That would mean 343 would basically have to develope two different campaigns for the next game. That would divide the cannon, and make the lore split along two different paths. Messy. Yucky. I hope not. I also think that Master Chief will have good intentions. I can't see him turning to a psychopathic killer, even after what he's been through. But what I'm thinking for this campaign is as follows: there are anomalies in deep space. Something bad is coming. A flood/forrunner/precursor threat. Now in the first trailer Chief is seen holding an AI chip, confronting what some have thought to be Mendicant Bias. Maybe that's why and where he went AWOL. Now many people think that the AI chip is Cortana's but I'm pretty sure the terminal that her chip was in got vaporized in Halo 4. What if it's an empty chip, and Chief wants the help of Mendicant Bias? He has more knowledge of the flood, the forerunners, and the precursors than anything else. He was on both sides of the war, and had a 40-something year discussion with the primordial (I think. That super gravemind guy). Moving on. The anomalies are slowly getting closer. ONI's getting nervous and to top it off the only one that saved them from the flood and Didact before ran away. They dispatch Locke's team to bring him back. Team may consist of Buck, Romeo, and Macer. Locke enlists the help of the Arbiter, and Thel tells him the stories of Halo 2-3. Meanwhile, Master Chief is running around with Mendicant Bias in his head. This is where my theory turns into guessing. Chief tries to find Halsey. It was made pretty clear that Chief holds Halsey's intellect in high regard in Halo 4. John doesn't think he can figure out this threat with only the help of Bias. So he rescues Halsey from the storm covenant. This initiates a conflict between the UNSC and the covenant, which explains the damage on Infinity. Chief is now aiding a war criminal. BOOM [ traitor > Now somewhere along this story Mendicant Bias has his own intentions, and [i]betrays them[/i]?..??..... Maybe???? But ONI and Locke see it as Chief's fault. All this time Locke is developing his opinion of chief. He may have had a few skirmishes with him. In the Master Chief trailer, when he asks Locke, "is this what you wanted," I think he's referring to the destruction caused if Locke prevents Chief from trying to save them from the anomaly. Now the "anomaly" hits. Chief and Locke's hostilities take a backseat too the new threat. Tldr: Chief tries to get Mendicant Bias to help with a threat. He betrays him and fuk's shit up. Locke thinks it was Chief's fault. I don't think they will actually kill each other in the end though.[/quote]
