There will be haters, even if you read all of this. But I will be using facts from games and previews. If you disagree on any of this, let me know below. I love halo. I really do. But after seeing most commercials, I think he will. Here's why. Halo itself is dying. Halo 4 wasn't good, nobody plays it, very few are exited for halo 5. It's just going downhill. I wouldn't be surprised it this was the last halo. In the Spartan lokke trailer (please excuse my spelling), it's obvious that he has accomplished something. Wether that's killing master chief or something else, I'm not completely sure. In Chiefs trailer, it sounds like lokke has done a lot of things to get whatever he was trying to accomplish. But, a the end of the trailer, chief says to him your journey is over. Mine is just beginning. It sounds like whatever lokke has done has required someone else to do something. I think master chief represents someone else. Someone just as powerful a chief. Foreshadowing for halo wars 2 maybe? Also, (not sure which commercial this is from) in one of the trailers, lokke is speaking to an elete (again, please excuse my spelling) about hunting down chief. At the end of it, he says that chief has gone "A-wall" and he has be told to hunt him down. We also see that lokke has a team of Spartans with him. Now the eletes. They have a history of killing Spartans. In halo reach, 5 Spartans out of 6 (I think, can't remember) die. 3 (I think) die from eletes. One got stabbed, one got shot by a gunship (maybe not eletes). If chief has a team of Spartans, and a group of eletes hunting him down, he may not come back. Plus, if he if no longer being supplies by the UNSC with ammo and weapons, he will have to start using alien weapons. And from my halo gameplay experience, most alien guns stink. So these are my reasons for believing chief will die. I probly made a ton of mistakes, like incorrect information, so just tell me what I did wrong. Please let me know what you think.
