The Forge

The Forge is an upcoming Event exclusive for Don't Starve Together, the first of a planned series of such events. It is projected to be released in November 2017. The event will include a 6-player co-op challenge, a Warrior Skin set, a new skin trader, new Mobs and Bosses, new combat perks for all Characters, new Weapons and Armor, and a new arena.

Beta Version
Starting on October 23, 2017 (2:00 pm Pacific time, specifically), a beta server will be up and running. The beta version will include skins, but players will be unable to link Forge drops to their regular skins, and will lose them when the beta ends. There are currently 498 Klei servers across 25 regions, with a total approximate capacity of 3,000 players.

Official Description
''With the Ancient Gateway activated, our survivors now find themselves trapped in a hostile world of fire and battle. They’ll need to team up to defeat the Battlemaster’s army and his champion, the Grand Forge Boarrior, if they have any hopes of returning home.''
