Feeling withdrawal symptoms now that you've finished The Last of Us? This new DLC should keep you going. Left Behind tells the story of Riley, set mainly as a prequel to the main events in The Last of Us. Without getting into too much detail and spoiling the first game for those who haven't finished it yet (and why haven't you?), Left Behind flashes between events that have taken place with Ellie and Joel, and those preceding their meeting. Ellie will find herself in tough situations from time to time, without Joel to take the brunt of the Infected's focus. Combat is drastically different from playing as Joel in the main game, as it should be. Without his physical strength, Ellie has to be a little more cautious about who she takes on. More interesting is watching the dynamic unfold between Ellie and Riley, and seeing how their relationship has developed. But Left Behind, most importantly, gives you one last chance to explore the destroyed world before bidding goodbye once more.
