wrong bsp

The sin episodes game is not a masterpiece, in general, nothing special,
but there are maps
for these maps, I wanted to have an editor
because they asked me
bsp viewers for halva are not suitable
and I have an ideal fix to rip out some items that would be useful to me
otherwise, to create a museum of torn objects from the unreal tournament - it has become a little boring
I would like to have map viewers, the ability to export items, and I will watch and store them on one of the standard maps,
thanks, even though the game had a console, otherwise
some would be generally uninteresting games simply MUST BE FORGOTTEN
and I'm not going to suffer over this - a lot of honor for such a toy
please tell me what to do, maybe who knows?
