Kobolds and Catacombs: UK and European Launch Date
Although Blizzard hasn’t outright confirmed that the next release will be staggered, it was revealed in a recent interview with geeksplatform that the tech to enable a simultaneous global release was still being worked on. Previous expansion launches have seen issues with server crashes and card rarity issues, after all, which explains why a partial rollout is preferred
That interview only took place yesterday, so it seems safe to assume that the UK will once again be left trailing behind the US. As a result, you can expect the UK and European launch dates for Kobolds and Catacombs to be more like 3:00am on Friday 8th December.

Kobolds and Catacombs: Overview
Here’s a quick overview of what’s coming with the new expansion if you’re just getting up to speed.
- A new roguelike Dungeon Run mode which sees you battling against eight bosses randomly selected from a pool of 48! You’ll have to craft your deck as you go, and select various upgrades.
- 135 new cards spread across all nine heroes and the Neutral card pool.
- A Legendary Weapon for every hero! (Even those who traditionally can’t wield them.)
- A new Spellstone card for each hero that grows in strength as certain conditions are met.
- A brand new mechanic for the game in the form of Recruit! This allows you to directly drag certain cards from your deck pile and onto the board for free.
- Special Unidentified Items which gain an extra effect as they travel from your deck pile and into your hand.
