weird how only one person ever responds to me on here and other peoples posts have pages of correspondence.
so i copied all of the headshot data from the dml that you links and put it in a new dml, zipped it, loaded it with priority on mod loader on top of scp3, and it is apparently not working. could it be because it was make for a later version of scp? that doesnt really seem possibly though because any additions or changes that work for scp5 should also work for scp3 assuming that the headshot data only alters original game data not found within scp5? dont know what to do to make it work now. out of ideas.
I don't think this is an issue since AFAIK SCPb5 has nearly the same object hierarchy and IDs as prior versions (and vanilla), with only a few exceptions. With standard weapons, projectiles, enemy vulnerabilities I'm not aware of any important differences.
I will try to get you the DML snippet you need to implement this when I'm able.
