Halo 3 isn’t even out, and the ending has been leaked on YouTube thanks to some guy who was able to get a copy off eBay prior to launch. This video contains MAJOR SPOILER for those serious Halo fans, and since you haven’t even played through the game yet, you shouldn’t watch it. I know this shouldn’t even be posted, but I feel like sharing. Don’t blame me for ruining it since I’m not in anyway forcing you to watch this video. It’s all up to you, so any complaints about it is a result of you being a stupid moron.

I urge you not to watch the video that’s embedded after the jump.

Seriously. Don’t click the link below. You won’t be able to take it back.

So, penny for your thoughts?
