This is a six-hour video that shows you most of The Last Of Us, beginning to end. It's achieved by recording linear gameplay (no dawdling or getting stuck or dying) and including all the cutscenes and story elements.
Why would you watch this, when half the fun is playing through the game's combat and exploration?
Let's say you really want to see what all the fuss is about with The Last Of Us, but don't own a PS3. Or you've finished it and want to revisit it. Or you're writing an article on it and want to be able to see vast sections of it without having to go back and replay stuff.
The vid's creator, dansg08, says he hopes " it succeeds in presenting the story in the way it should be experienced".
If you want to watch it, remember, it's six hours long, so get some popcorn.
