As it’s proven in the past, Activision Blizzard is doing very well with Hearthstone: Heroes of Warcraft, its hit PC/mobile game where players use cards from decks to battle other players online. And now, with the announcement of a Grand Tournament expansion, business is likely to pick up even more.

Per a report from PC Mag, Blizzard announced the expansion yesterday, with Grand Tournament set to arrive for both the mobile and PC versions next month. It will feature 1332 new cards that can be won through Hearthstone‘s Arena mode, although players will also have the option to purchase them direct, using either real money or in-game currency.

The expansion will enable players to visit the cold confines of Northrend, where the argent Crusade once held a tournament to get together the greatest fighters in Azeroth and prepare them for a forthcoming battle. “The competitive atmosphere’s just a lot more playful (and a bit warmer) than it used to be,” said Blizzard on the official blog page.

Hearthstone has become a global success for the company in a short amount of time, effectively providing a way to impact the global market while keeping its highly popular Warcraft theme in mind. It’s also gained popularity on the Twitch front, with hundreds of gamers, professional and casual, broadcasting their sessions on a daily basis to a growing audience.

With that, Blizzard will more than likely begin a promotional campaign to get the word out about Grand Tournament. The company didn’t go into details, but a new TV trailer – similar to the one it aired earlier this summer for Heroes of the Storm, viewable below – and plenty of online ads are to be expected. It wouldn’t be a surprise if Blizzard teamed up with bigger partners, such as Twitch, to feature a glimpse of what’s to come with the expansion.
