Terrain genarator question

A few years back i found a warhammer 40k battelfeild condition Generator.
It had special rules that were rolled for at the beging of the game on 3D6.
that effected any part/s of the game depending on the result, for example

eg: If you rolled a 354 on 3D6 Chaos maw-all movement thought difficlt terrain became dangurs as the plant trys and eats and your troops.

If you rolled a 364 on 3D6: warp time - everything moves D6", vehicals role 2D6" in the movement phase instead of there standered movement.

I'm wondering if anyone has seen this or knows of something like this?
