Either Crytek are quietly trying to cause no end of hell for EA, or the wrong Crysis demo got released and there are a whole lot of panicking, screaming, crying German developers right now.
First, the script for the entire game was discovered lurking in the demo files.Then a simple config file edit activated supposedly DirectX 10 and Vista-only graphical effects in DirectX 9 and XP. And now, someone faffing about with the bundled level editor has managed to dump a load of good stuff from later in the game into the demo map and make it playable.
Basically, if you want to know all this stuff, you need to head to “C:\Program Files\Electronic Arts\Crytek\Crysis SP Demo\Game\Localized” where you’ll find the english.pak file. Open it up with winrar or something. Inside the compiled docs bit you’ll find an enormous amount of 27 (Count ‘em!) pages of plot based gubbins - and new screens - which you can absorb at your leisure and be able to tell people that the cake is a lie, or local equivalent thereof.
.. always happens ..
