At the SAS mod we were going to be making The Iranian Embassy siege, the only problem is that OFP indoor combat as we know is sh*t, with clipping problems, ppl falling through floors and getting stuck between objects etc.
But all these places anyway would look sweet even if you couldn't go into them. But ppl trying to make missions inside should be wary of the problems that will occur,
Great Idea though for use in cutscences ;D
