In an E3 roundup on his blog, Notch wrote, 'The idea with this update is to flesh out the game a bit, making it reward exploration and combat more.' Although he added, 'We're keeping the details secret so people can get surprises,' Notch wrote back on July 7, 2010 that Adventure Mode would be one of the three game modes in Minecraft (the other two being Survival and Creative), and would include a health bar and an inventory, but would remove the player's ability to place or destroy blocks. He said the value of this is that 'people can design "challenge maps" in creative or survival mode, then share them with people so that they can try to beat them in Adventure mode.' Interestingly, Notch also announced the release of the Minecraft source code to a small group of mod developers, in his latest blog post."
