“The Last of Us: Left Behind,” the survival horror game that was originally only available as a single-player downloadable content, will be available as a standalone download on Sony’s PlayStation 3 and PlayStation 4 on May 12 for $9.99. Playstation 3 players will be able to purchase the full game, factions multiplayer mode and treacherous territories map pack bundle for $29.99. Playstation 4 users will have access to the pack for $39.99

“If you haven’t had a chance yet to check out ‘The Last of Us,’ this is a nicely priced gateway to checking out the world and characters so many people (and critics) loved,” Sony said in a blog post on Friday. “While part of the story of ‘Left Behind' takes place during the main narrative arc of ‘The Last of Us,’ I think some of the best and most touching moments of any game in recent memory occur during the prequel segments.”

“The Last of Us” launched for the PlayStation 3 on June 13, 2013 and on June 20 in Japan. The title sold more than 1.3 million units during its first week and as of last summer, has moved more than 7 million copies.

In the game, the player takes on the role of Joel, a single father who must travel across a post-apocalyptic United States in 2033 to protect a young girl named Ellie and deliver her to a resistance group. The group, who call themselves the Fireflies, believe Ellie may be vital to curing the zombie-like infection that has destroyed the planet.

Naughty Dog worked on the title in secret for two years after completing 2009’s “Uncharted 2.” The game was teased before the Spike Video Game Awards in November 2011 and was publicly shown in a gameplay demo at E3 2012. 

After its release, the game received critical praise, earning a 95.04% on GameRankings.
