Ellie has been confirmed as a playable character with brand new gameplay via the new The Last of Us Part 2 demo showcased during PlayStation’s E3 press conference. Armed with a bow, a backpack, and a knife, Ellie snuck around a forest environment in the demo.
The demo featured an intense combat scenario bookended by scenes of Ellie dancing with a previously unknown character named Dina. According to an update by game director Neil Druckmann on the PlayStation Blog, “Ellie is now 19 and has found a semblance of peace and normality living in Jackson” at the time of the demo. Ellie has found some peace but it is “disrupted by a violent act.”
