The Minecraft universe is set to expand once again. Today at Minecon, developer Mojang revealed a new dungeon-crawler set in the blocky universe. Called Minecraft: Dungeons, the new experience is described as “an all-new action-adventure game inspired by classic dungeon crawlers, where you’ll constantly discover new weapons and items that will help you defeat a ruthless swarm of new-and-nasty mobs. You’ll fight or flee through canyons, swamps, and — of course — mines!”

Dungeons is, naturally, set in the Minecraft universe, but it looks like it will offer a more structured experience than the sandbox building game. You can explore solo or play with up to four friends. It seems like a pretty natural extension of the best-selling Minecraft, which is no stranger to spinoffs, including the narrative-focused Minecraft: Story Mode. Minecraft: Dungeons is expected to launch next year on PC.
