Naughty Dog will finish out its planned season pass content for The Last of Us with new weapons, additional multiplayer maps, and a new single-player gameplay mode as part of the upcoming Grounded Bundle.

Grounded Mode puts a new, difficult spin on The Last of Us' single-player campaign, pitting players against "relentless, smart, and brutal" enemy mobs throughout. Naughty Dog notes that survival in the new mode will be "near impossible," and claims that the "Completed Grounded Mode" challenge will be one of the most difficult Trophies players will earn.

The Grounded Bundle additionally features the Reclaimed Territories Map Pack, adding the Wharf, Capitol, Coal Mine, and Water Tower maps to the game's multiplayer component. Players may opt to expand their arsenal with the Survivalist Weapon Bundle, which introduces the multiplayer-only Specter, Double Barrel, Enforcer, and Launcher weapons. Also arriving are the Situational Survival Skills and Professional Survival Skills bundles, which enhance character abilities in online battles.

Grounded Mode will be priced at $4.99 as a standalone download. The Reclaimed Territories Map Pack is priced at $9.99, the Survivalist Weapon Bundle is $5.99, and the Survival Skills Bundles are $3.99 apiece. All upcoming content is included as part of The Last of Us' $19.99 season pass, but interested players may want to hop on the deal soon, as the season pass bundle will be discontinued in mid-May.

A release date for Grounded Bundle content has not been announced.
