The Last of Us director Neil Druckmann is keen to make a Half-Life title.

Last week, Druckmann tweeted out a photo Merle Dandridge, the actress who played Marlene in The Last of Us and Alyx in Half-Life 2, among others.

The caption: “Look, Valve, all I’m saying is you give us the Half-Life license and we’ll take care of the rest.”

Druckmann is currently working on Uncharted 4: A Thief's End, which is due out in March.
