First of all thanks for all your comments on the demo. :) (go to hell if you found a bug and even dared to post it :P )
Okay, but now lets get to the main content of this post: Like already announced in the forums, we've got another little present for you: A file with lots of tips and a walkthrough for the demo mission that also works on "hard" difficulty (and there are lots of nice screenshots in it ;) ).
You can download it here.
We hope you're still having fun with the demo, maybe even more now you've got this little help file, and want to wish you a happy end of this year and an even happier next year. :D
See you next year,
