I am still looking into the PS3 files for this mod. It looks like I may have better luck there than on the 360 where everything is encrypted in a currently unknown format. There a ton of LUA files missing from the PC DLC files. ATM the only way to get the DLC operational seems to be to rebuild these files from scratch. There is a problem however. It looks to me like the LUA files are generated by the editor when it spits the level out after being built. The lua files contains a bunch of scripting that is very level specific. Without the editor and certainly without help from multiple people re-writing these files could take months.
I have noticed that most levels follow a very similar format for specific script sequences. However there is another issue. Since some of the scripts are responsible for model/FX placement and we would likely have to do that manually this means that we will probably have stuff floating in the sky or rotated funky until we figure out the coordinate system and even then this will take weeks of debugging.
I am still hopeful that I can at the very least dump these lua files from PS3/360 to make life much easier, but only time will tell.
