I thought the ending was executed perfectly. Not too cheesy, not too dramatic, but powerful where it needed to be. When Six was told to get on that Pelican, it didn't take him long to say "you go on ahead sir" and man that gun. But he didn't do it with the 'I'M A PATRIOT ./PROUD' act, he didn't do it with a heavy conscience. He did it as a Spartan and he did it knowing that he was going to die a man. (Or woman, i'm using the term 'he' because that was my Six) This wasn't some Metal Gear bullshit about sacrificing oneself for their country, nation or people, nor was it some Master Chief 'Nothing i do ever fazes me' man of steel stuff either. It was purely acceptance of the situation and what's the come. Manning that MAC gun and firing the orbital round into the gut of that super carrier was the player's final 'fuck you' to the covenant. When they come to put you down like an animal that's gone feral, it's very subdued. They aren't hunting you vindictively and you're not meant to feel like they're killing you out of spite. The solemn atmosphere and minimalist surroundings amplified by the ever increasing but not too busy Covenant forces reinforce this. Six didn't go down kicking and screaming, it's like watching someone gently suffocate a victim to end their suffering. The covenant probably didn't even need to kill Six in the manner they did as the planet was going to be glassed anyway; it was a matter of honour and recognising a worthy and honourable opponent. That's how i like to see it, anyway. When we, the player, look through the visor at Six fighting for his life right up until he's killed, it's like we (the 'soul') have left the body of Six. It's powerful stuff. The very fact Six went down fighting means that his sacrifice of staying behind wasn't cheapened by an overkill laser beam from space. He went down like a soldier, something which has been seen as a strong positive in culture for a long time, that it's 'honourable to die on one's feet than to bend on one's knees'.
