14 Mind-Blowing Video Game Fan Theories That Change Everything

4. You Probably Killed Nathan Drake - Uncharted 3/The Last Of Us

An oldie but a goodie (if we class 2011 as old), Uncharted 3 actually shows that Naughty Dog were working on The Last of Us' core idea two years before its release.

As such, inside the opening level which takes place in a British pub, you can find a copy of 'The Overseer' (a riff on The Guardian), that proclaims "Scientists are still struggling to understand deadly fungus". If we go with the assumption that this is less an easter egg and more proof that the worlds of Uncharted and The Last of Us are combined, Nate, Sully, Elena and co. would all most likely have turned into zombies in the near future after the franchise concluded.

Next time you're battling through the fungal-headed hordes, take a moment to look out for one with a half-tucked shirt and a ring around his neck - chances are we've all blown Nate's head off without even realising.
