What happens in the Halo 2 ending?
Master chief goes back to earth
Halo: Reach is the ending of the Halo games, it shows that the halo games were a story. It started with the first one, and they were all looking for the Halo which you find in the en of the game. There won't be anymore Halo games so that's why your spartan finally died in the ending and the Covenant was pushed off of planet Reach
At the end of Halo, it turns out that the Arbiter and the Chief managed to activate Halo and escape through the frigate. However, while the Arbiter turns up on Earth, Chief and Cortana go flying back into space, into unknown areas. Cortana informs Chief that it might be years until they get found. That's the ending of Halo. PS. The Legendary ending shows an extra cutscene at the end where it shows the battered…
there is no alternate ending like there was in Halo: CE, however, if you beat it on any difficulty other than easy you will see an extended ending where Master Chief and Cortana are floating in space and are not actually dead. If you go to youtube.com you can see the extended ending without having to beat the game again.
Will there be another halo game after Halo 3 not necessarily Halo 4 following the open ending to Halo 3 I already know Halo 3 Recon I'm not talking about that annother one following the storyline?
Yes and no. You do not need Halo 3 to play ODST. And you do not need to have played Halo 3 to play ODST. It is an expansion of the Halo storyline. I happens concurrently. No its not this is not an expansion of the story this is just another part of the story.... so basically whats happening in the game halo 3 is happening at the same time as whats happening in halo…
