We’ve done it. We made it past all of the Curse of Naxxramas bosses we’ve encountered so far, and we are finally ready to push through to the end.

Developer Blizzard unleashed the final part of its Curse of Naxxramas downloadable content for Hearthstone. The last of five episodes went live at a minute before midnight Pacific time, and — just like in previous weeks — it adds a series of new boss fights. Gamers can hop into Hearthstone right now to purchase the latest episode for $7 or 700 in-game gold. Players also have the option to pick up the entirety of Curse of Naxxramas in a $20 season pass.

Like with the rest of the adventures, gamers who beat the finale will get a handful of new cards that are impossible to obtain without crafting golden versions. These cards feature new capabilities that could change the way some people play.

With the release of this finale in the Americas, all of Curse of Naxxramas is available worldwide.

Curse of Naxxramas is Blizzard’s first big effort to release extra content for its free-to-play card battler. The company has previously only made money from selling booster packs and entrance to a special Arena mode. Hearthstone is important to Blizzard, as the company looks for ways to bring in cash while it slowly loses monthly subscribers for its popular World of Warcraft MMO.
