Adventure

Adventure Mode, formerly Dungeons and Levers could be an upcoming game mode. Currently, focus on Adventure is an update to the base game, not a separate mode. .

Notch has said that the Adventure update (or similar) will come in Beta 1.7. Note that this is not necessarily Adventure Mode, but instead a way to "flesh out the game a bit, making it reward exploration and combat more".

Features

 * Will have programmable maps, buttons, pressure plates and levers.
 * Possibly not being able to place or destroy blocks
 * Numerous randomly generated dungeons using a similar code from the current dungeon generator.
 * Possibly a map editor similar to the one in Minecraft Classic.
