Minecraft: Explorer's Pack for the Xbox One is currently on sale at Amazon for just $22.99, down from the $30 other retailers have it at right now.
You can also grab this deal at Target.
Released last November, it includes the Minecraft base game, along with the Explorer's Pack DLC which contains extras like a Chinese Mythology Mashup, Natural Texture Pack, Biome Settlers Skin Pack and more. New features were added to the game too, like infinite worlds, the recipe book and marketplace.
Minecraft is super expansive. It has cross-platform play so you can connect with players on Windows 10, mobile devices, and even the Nintendo Switch soon enough.
