Can some one please explain halo 4s ending to me. I know it's late but i haven't the slightest clue what i was watching or what that bad guy was saying. I felt like they did a poor job of explaining what was going on.
I don't even know who the bad guy was (what race) and feel like maybe i would understand more if 343 spent more time fleshing out the story rather than Cortana

It has a lot to do with expanded universe like the books. The main villain is the didact, a forerunner, the race that built the halos and used them to initiate mass genocide when they were overrun by the flood. Pretty sure it says that in the game plenty of times, and the didact was in the Halo 3 terminals.
