Dark Messiah Elements (XBOX360) - extracting .bf/.bfm files (multiplayer map sample)

[xelar]

Hello,

I would like to try to see if would be possible to port Dark Messiah Elements multiplayer map (XBOX360) to PC version. I have the sample map (L_MP1_X360) files in .bf/.bfm archives, but I have no knowledge how to extract them properly.

I have tried many different options:
- QuickBMS scripts
- .bf extractors from github
- Unpakke

but with no luck
