The last DLC for The Last of Us is set to release tomorrow for North America with Europe seeing a release this Wednesday. You can view the launch trailer for Grounded right now and see just what all the DLC includes.
One of the main features for Grounded is the higher difficulty level. Naughty Dog has stated that Grounded will make the game much more challenging making survival almost near impossible. Besides the difficulty increase, there will be four new maps added along with the Survivalist weapon pack containing four new weapons. An additional skill set will also be available within the DLC.
