The night is dark and full of terrors in Hearthstone's next expansion, The Witchwood. Our first look at the next set of new cards coming to the game was in a Blair Witch-style reveal video, but as a pre-cursor to more card reveals happening throughout the coming weeks, Blizzard's Dave Kozack and Dean Ayala dropped by the GameSpot office to discuss Witchwood's development.

And for even more Hearthstone talk, check out the video above, where we play through the Kobolds and Catacombs Dungeon Run along with mission designer Dave Kozack while discussing the upcoming Monster Hunter mode. We learned a very valuable lesson in this (embarrassingly unsuccessful) run: never underestimate your opponent.
