Possibly the big Crysis demo suprise

From looking through the file system, there is a Power Struggle multiplayer Shore map included with the demo. The editor can run it, with some errors. The problem is getting the game to allow the multiplayer menu to be accessed. I haven't figured that out yet and looking through the config files and the registry entries haven't yeilded anything obvious.

Also, Folders.ini contains the line:
UserFolderMPDemo = "My Games\\Crysis_MP_DEMO"
