A Mortal Kombat egg is featured in Episode 3 of HBO's The Last of Us TV series. Ellie stumbles upon a Mortal Kombat II arcade cabinet partway through the episode.
Mortal Kombat Easter egg from The Last of Us
The Last of Us Mortal Kombat II Easter egg is difficult to miss as the arcade cabinet is seen from several angles, and Ellie even discusses the game with Joel.
Ellie's "friend" is most likely Riley. If Mortal Kombat is anything like the game, you'll see it repeated during a flashback to when Ellie and Riley were together in an abandoned mall.
"The Turning" has been replaced with a fighting game similar to Mortal Kombat. It featured a character named "Angel Knives," who had her punch a hole through her opponent before decapitating them.
The Last of Us HBO has announced its second season. For those who haven't seen episode 1, it is now available for free on YouTube.
