Summary says most of it. I'm uploading a TK2.ZERO all.spawn patch for the 11-10-10 beta. The patch adds many things into the all.spawn instead of having them in a script. The patch itself is a beta as only the first 4 levels have been edited so far (Cordon, Garbage, Agroprom, Agroprom underground). You will get a much better taste of what TK is supposed to be though. Finally, you will need to start a new game for the changes to take effect with this patch.
