Obsidian Conflict Forums

Are they supported by Obisidan, I've seen I think evildead, and tantrum, have them! How to add a map briefing, I've had a play with Map properties, but haven't quite figured it out? I'd like to add the story and maybe just alist of objectives.

thnx.

Obsidian folder -> maps -> cfg

[mymap]_briefing.txt
in maps/cfg

Thank you so kindly!
