The only other mods I have active are support drones, expanded terror reworked, death splash, and celebrate diversity (though that one seems to not do anything at the moment)
It does it for both regular and terror missions. expanded terror worked on it's own, reaver's doesn't work even without anything else.
Reaver's remix by Lord Kane does the same thing.
and yeah, I'm the kooky manjaro linux guy.
