"Necessary changes being made" is the translation I have. It's a legal term, AFAIK, though here it's being used in a biotechnological context.

During WW2, Japan was asked to respect the existing treaties regarding POWs. The answer was something like "ok, but mutatis mutandis." I think we all know what happened next.

OK, I think you need to explain that(mutatis mutandis) and the various other clues you scattered in the sourcebooks. Treat it as supplying game info as opposed to fluff write up.

The story is further developed in both SoLA and System Failure (the latter should be available pretty soon, I believe). Sorry if I can't be more specific at the moment.

That's about as clear as mud.

Mud with bits of glass, jagged metal and biohazardous waste.

Right in the eyes.

Or clear as Swordfish Musterdball
