Naughty Dog has released details on The Last of Us' third and final DLC drop, the Grounded Bundle.

The upcoming bundle offers a host of new multiplayer content, including the Reclaimed Territories Map pack featuring four new maps, along with four new weapons and eight new skills.

The Reclaimed Territories Map Pack will also be included with this summer's PS4 re-release, although it isn't yet clear whether the rest of the Grounded Bundle will also make the leap to next-gen.

In addition, the Grounded Bundle also contains a new difficulty mode - the super tough Grounded Mode - which tasks players with playing through the single-player campaign against "relentless, smart and brutal" AI.

And finally, all players, regardless of whether they purchase the content or not, will receive a new weapon - the Full-Auto Rifle - for free.

The Reclaimed Territories Map Pack contains:

Wharf: Set in the rusted-out docks where Joel encountered Robert, the Wharf map features close quarters gameplay, two snipers nests, and a giant boat. It's full of good opportunities for climbing, flanking and stealth.

Capitol: Set in Boston, the Capitol Map features indoor and outdoor gameplay. It encourages the intelligent use of flanking.

Coal Mine: Set in Colorado, Coal Mine is a winter map that is spotted with abandoned buildings. It's a spacious map that has long lines of sight and a bridge that's a perfect perch for snipers. The dynamic snowstorm obscures the view so be on your toes.

Water Tower: Set in Lincoln, PA, the Water Tower map features two primary chokepoints for some deadly face-to-face confrontations. It's mainly an outdoor map with a few indoor areas and some very unique lighting. It might seem open but it's really a tight map that's perfect for close quarters melee.

A release date and price for the DLC has yet to be confirmed. For the full details on the pack, head through to PlayStation Blog.
