The final expansion for the hit PlayStation 3 exclusive The Last of Us drops this week with Reclaimed Territories. Check out the preview above for a look at the new mutliplayer maps.

As well as the new mutiplayer maps and guns featured in the video, the game will also get an upgraded difficulty level for single player called Grounded Mode that the developer describes as “near impossible.”

The Last of Us was a huge hit on the PlayStation 3 and as you might expect will get a port to the PlayStation 4 set to drop sometime this summer.

Developer Naughty Dog will host a Twitch livestream today at 3PM ET (below) featuring an in-depth look at the new weapons and maps. Reclaimed Territories is free to Season Pass holders but will cost $9.99 to those without. Also available are new weapons and skills pack starting at $3.99.
