Here is our very first Adventure Map, The Crash, it is a short two player Adventure map so you will need to put it on a server, although it can be played in Singleplayer, it will be a bit weird. This took us a few hours to make, because we had never made one before and it is quite short, but we willl be making a much better, detailed one which will out sometime this week. SO without any further ado, here is the link!
To Install the Map on a Multiplayer server, set it up as usual, then in the server properties text file, rename the server level so that it has the same name as the world file you downloaded.
To Play on Singleplayer mode, simply paste the world file you downloaded into your save file in the minecraft folder which will be in the Application support folder on a Mac, and on Windows it will be in %AppData%/Roaming.
To install the Texture pack make sure you have downloaded the latest version of the patcher and then put your Texture pack in the Minecraft/Texture Packs folder and then patch, it should be ready to use, if you are on mac then you will need to place Minecraft in the folder of the Texture Pack you just downloaded and then patch it using the patcher.
Enjoy, and please post your thoughts on the Map, and leave any suggestions on what our next one can be about, and what challenges you would like to face, as mentioned before, this was purely created just to see whether we liked the idea of creating Adventure Maps and you can expect a bigger, better one sometime this week!
