Adventure maps are adventure-based experiences for the player to complete and explore. These usually follow a set story, although they do not have to.
The main thing that sets these maps apart is that they are rarely survival maps. They are typically meant to be a new game inside Minecraft.
Some adventure maps are complete games! Other adventure maps are collections of mini-games. These are similar to Mario Party and are a lot of fun with friends!
There are also exploration and collection maps. These are maps with amazing scenery that are meant to be explored and items are collected along the way to complete the game.
The adventure map possibilities are endless!
