Adventure

Adventure Mode, formerly Dungeons and Levers, is an upcoming game mode.

Not much is known yet on what Adventure Mode will include. It is likely that Adventure Mode will increase the distinction between the Survival and Classic modes, making Survival more like the beta Minecraft, where the object is only to build and survive.

It is a possibility that Adventure Mode will include permadeath like Hardcore mode, making it rogue-like in nature.

There can be NPC's that will give you quests and shops.

The "Adventure Update" spanned updates 1.8-1.9 and was meant to be an update to "flesh out" the game. Adventure Mode should not be confused with the "Adventure Update". Minecraft Beta 1.8, the first quarter of the update, was released on September 14, 2011. This mode has not been released yet; in the Release Candidate there are no signs of the "Adventure Mode".

Features

 * It will have programmable maps, buttons, pressure plates and levers
 * Blocks cannot be placed or destroyed
 * Numerous randomly generated dungeons using a similar code from the current dungeon generator

Similar mods
The mod for 1.8, AdventureCraft is very similar to this mod. It has some extra tools, a debug mode etc. It also has dual wielding and uses the bin from the current minecraft from your .minecraft to make it's own. Making, editing and creating maps is also available. Multiplayer is not available as it still has some bugs. The main menu also adds a new feature which allows you to download maps manually from the title screen.
