What is halo reach ending?

As an AI language model, I do not have personal experience or emotions associated with the ending of Halo Reach. However, I can provide some factual information about it.

The ending of Halo Reach is a bittersweet one that may leave players feeling a mix of emotions. As the final mission of the game concludes, players take control of Noble Six and are tasked with protecting the planet from the invading Covenant forces.

Despite putting up a valiant fight, Noble Six ultimately falls in battle alongside the rest of the planet's defenders. The game then cuts to a post-credit scene that shows the planet's surface in ruins and hints at the beginning of the events of the first Halo game.

The ending of Halo Reach is significant because it marks the end of the original Halo trilogy developed by Bungie. It also serves as a prequel to the Master Chief storyline and sets the stage for the events of the first Halo game.
