10 Hidden Video Game Sequel Clues You Totally Missed

4. Ellie's Mother From The Last Of Us Part II Is On This Uncharted 4 Poster

Uncharted 4: A Thief's End's epilogue sequence briefly casts the player as Nathan Drake's teenage daughter Cassie, and those who take a quick scan around her room will find a poster for "The Last of Us: American Daughters" on the door.

It appears to be a comic set within The Last of Us universe, and features a young woman bearing a remarkable physical resemblance to series protagonist Ellie, except for the fact that she's clearly heavily pregnant.

This was fairly cryptic until Naughty Dog finally announced The Last of Us Part II over six months later, and revealed the presence of a woman who is almost definitely going to be Ellie's mother, Anna.

Between Naughty Dog cheekily confirming that the character has a four-letter name and the game's director Neil Druckmann tweeting about her on Mother's Day, there doesn't seem to be much room for ambiguity here.

Despite the game not being formally announced until December 2016, our first actual look at a piece of art related to the game came many months prior and we didn't even know it.
